Hello I have this question somewhere in the fourm, but with no luck noone responded :[

I'm writing this again, because I just feel if i paid for the product, I should at least get the service that i paid.

Anyhow this is my current set up ( ALL new item that was bought at FRYS electronic's)

Case: NZXT Phantom (white)
CPU : Intel i5-2500K
PSU : Thermtlake 600W
Motherboard : P8Z68-V ( I was just gonna get regular mobo, but this guy that worked there pushed me to get it .... and right now i regret it so much)
GPU : eVGA Geforce 460gtx
RAM :Corsair CMZ8GX3M2A1600C9B 8GB Kit 2X4GB 1600MHz DDR3
CPU-Cooler : Coolermaster


Building the computer took a little more than I thought ( didnt plug the ram tightly into the mobo ) after figuering that out in 2 days T___T. I installed windows 7 64bit.

Installed the drivers from Asus mobo cd, ( had to downloading and install some of the new ones from the internet)
Turned my computer off and fell a sleep, after waking up and trying to turn it back on it WOULDNT T__T;
I was about to cry again but i just took the power cord from the back for while and plugged it back in. After doing that the computer reboots into AMI (pre bios) menu where it keep saying overclocked failed ( when i didnt try to oc).
Also the ram said 1333mhz instead of 16000mhz. Thinking it had something to do with the ram, called asus support and the first guy helped me set up the 9-9-9-24 thingy. After he helped me the computer said 1600mhz in ram so i thought the problem was fixed.... but it wasnt next day same problem computer turns on ONLY after i unplug the powersupply. 2nd guy in ASus said did u screw in the safety screwthingy before setting down the mobo. I relize i forgot to do that, and he said well all the power from the psu is going to ur mobo and ur mobo is touching the case. And assured me by adding the screw will solve the problem. NOT.

The problem is still on going, I'm reading more and more about simiar problem, and i only see the asus bios update as a solution. However right now i don't trust asuss mobo no offence, but the bios does not save my stuff.

I changed the ram to XMP profile and next reboot i see it went to manual and stuff and etc.
I'm pretty sure someone said wait for BiOS update, but i just want to know if anyone was able to fix it without the bios update ty.

For the set up you have, I'd question that a 600W power supply has quite enough juice to keep things from being flaky... You're at the lower end of the recommended wattage for the board + gfx card.

A 600 watt PSU is more than adequate.

One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card with similar power requirements to yours, a Gigabyte EP45-UD3P motherboard, 3 hard drives (2.6 TB total) and an optical, and a Soundblaster card all powered by a Corsair 750TX.

Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.

What "safety screw thingy"? I have built a lot of machines, and none of mine have a safety screw thingy as far as I know.

I have used ASUS motherboards for almost 20 years, and had next to no problems. I've had to return just one out of maybe 30, and that one was due to a fault in the Intel chipset.

It sounds like your machine's CMOS battery might be faulty - I don't know if that particular motherboard has a coin battery on it. You could try resetting the CMOS, setting all the parameters again, then switch the machine off and leave it overnight. If the same problem recurs, I'd return the motherboard. A BIOS update won't fix a faulty battery.

BTW: I'm using a 650W power supply (Seasonic X650) to power an ASUS P8Z68V Pro motherboard, i7 2600, 8 GB 1600MHz DDR3, and a GTX 580 - similar to your configuration, but with a much more power-hungry video card, and I'm having zero problems, so I would not expect your power supply to be the source of the trouble.

Hey thank you for responding to my post. the safety screw thingy was standoff. I've been playing wiht computer all my life and never knew about that T__T;. Also he said before doing anything put the mobo on top box and see if that works. but im scared to take it out now.

My dear friend as you can see in manual that your motherboard is having many small LED in motherboard which tells you that if any of your hardware is malfunctioning. please check LED of motherboard. there are different LED in your motherboard show status of different hardware like RAM, Processor etc.

June 14, 2011 5:16:55 PM

Yea I know that my mobo has different lights that come on. However all the red lights are off when my computer turns on. The only light that stays on all the time is POWER red light, and the green light by ram side

When you press power button on your cpu ( cabinet ) does fan of your SMPS ( Power supply ) starts??????

what is the status of other fans in your computer like processor fan cabinet fan etc.

Is there any beep when you switch on the PC. because beeps also gives information about error occured during POST ( when computer starts )

try to hear that beep and then as per number of beeps and duration of beeps like long beeps OR short beeps you can check the meaning of that beeps in internet, then you can easily troubleshoot your problem and

IMPORTANT

There is one more question for your when you purchased your motherboard, how many locks were there for RAM

i means when you insert RAM into motherboard there are 2 locks which hold the ram within the ram socket........... so check and reply

Are there 2 locks holding ram from left and right tightly or just one lock holding ram either from left or right...........

Hi All,

I am experiencing very similar problems with my new build that's only 2 days old using similar gear and same motherboard... first sign of problems is when I put it into sleep mode in windows 7, that caused the PC to shut down completely to the point it did nothing at all, after going back to the shop and getting some advice I pulled out the CMOS battery and used the onboard jumper to clear and that seems to have gotten it back up and running...

Since then I have updated the BIOS, graphics card drivers and I am still having random problems, sometimes on bootup I get the overclocking error like you, I have also had the PC crash out to a dos screen with some error about rebooting with a bootdisk (cant remember the exact message now)

Its really dissapointing because I was so excited with this new PC and its soo unstable I don't know what to do... I have left most settings in auto, which I assume is letting it overclock and drive the gear harder, I am wondering if I try and manually fix it all at the recommended speeds??? :( 

Also to answer the last question the slots for the RAM has one side that opens/closes and the other side is fixed....

Cheers

you are right as i personally contacted ASUS SUPPORT because i was seeing lots of threads here stating this problem, that unable to repull after put it into sleep mode. that is a bios error and asus will soon correct that error by providing an bios update. and about your overclocking issues just install your all asus utilities and by using overclocking utility put your processor to stock frequency.... i bleave it will work fine. let me know if this hellp.

Because i am going to buy same configuration without addon graphic card on this saturday. :-)

If you found any othersolution to overcome this problem kindly reply to me also.

Thanks.

Yes recent bios update has been upload by ASUS, you better download latest bios for more stability


Enjoy.

Im trying to update bios anyone have any idea how to do it easy ?

My head is about to explode :X
July 12, 2011 4:26:42 AM

get a usb flash drive, goto asus.com
July 12, 2011 7:43:50 AM

does this new beta bios resolves the problem? didn't got time to test it on my system yet..
July 12, 2011 8:05:45 AM

You can try to update the bois. I do not know if it really works, you can try it.
July 13, 2011 7:51:37 AM

finally figured it out, the CMOS clear jumper was missing..after setting one in it works perfectly so far
July 20, 2011 12:08:10 AM

how do you do that ?
July 29, 2011 3:46:39 PM

I had the same board, with the same CPU, but opted to use onboard video to save some heat. And after leaving the PC running for 6 hours or so, I come back to a non responsive PC. Pretty similar to what koc was experiencing. I am using Win 7 64bits.

I finally solved my problem, but I want to point out that all the people who given you advise previous seems like old school tech. And no offense, just because you been in the field for 20 years, doesnt make you an expert and doesnt mean the way you troubleshoot works anymore. If anyone is still suspecting HW, then follow first rule of troubleshoot. Unplug everything, Leave just 1 memory module, CPU, and onboard video (if none a discrete video card). And start your machine, repeat the process one component at a time, (in your case a few hours between because thats when u experienced the problem). Until everything is plugged in, or identified the hardware that is causing the issue. Moving on.

If hardware is not the issue, and you think it the PS, just do the math:
hard drive 5 - 20Watt each
Video card, 95 - 160Watt each
Sound (discrete card) 5 - 10Watt
CPU 65 - 135 depending on CPU
MB (for all the onboard devices) 20 - 40Watt
Fan 5Watt each.
Memory not a lot, but dont know the figures.

Finally software, this is where my problem is. and if you read a lot of forum, you'll find that many motherboard has trouble with the new Sandy Beach speed step and sleeping problem. Where the MB sees no activity, it throttle down the CPU, and many time, when you try to wake it. I just doesnt know what to do. and become unresponsive. Best solution. In windows, set all your power setting to not go to sleep or hibernate.

Seriously, with all respect to the techs, motherboard now don't have 2 locking on memory, just 1 per slot. The bottom bracket has a grove where the memory sits on, and rely on just the top lock to secure it in place. And finally to koc. If your MB snap in half because you put too much pressure on the board. You did not seat the MB correctly. All ATX has screws near the memory modules, that means there are copper backing to those screws. Should not snap. I have try standing on one before didn't snap (was a dead MB). Also, don't bother with the CMOS jump, cuz, missing means you are not clearing it. having one there means you going to kill your CMOS.

Hello KoC and tomshardware peepz,

First time post figured since I had the same setup I could shed some light on the subject

CPU - i5 2500k
Mobo - Asus P8Z68 Deluxe
SSD - 180GB Corsair GT
RAM - 16GB G.Skill PC3 - 1600

developeraslam was on the right track. You would of found your answer on page 2-19 of your motherboard user guide. I'll quote from the book...."The POST State LEDs of CPU, DRAM, VGA card, and HDD indicate key components status during POST. If an error is found, the LED next to the error device will continue lighting until the problem is solved. This user-friendly design provides an intuitional way to locate the root problem within a second." Btw Asus Intuition-al is not a word lol. But anyway there you go KoC if your green LED next to the DRAM is still lit I would check to make sure they are all seated correctly first before doing anything else. If that doesn't work try reading the part in the user guide about the MemOK! feature.

Also in your CPU User Guide it explains that due to the chip architecture RAM clocked at 1600 will be rated at 1333. It goes on to say more of the same about the 1800 and above RAM chips, so that is normal at least.

Hope this Helps and your Welcome

- Old School Tech.

P.S. Hey churkl ease up off the old school peepz. With out them were would you and your rig be? show some R.E.S.P.E.C.T please.

I've had no end of issues with my new setup.
Asus P8Z68-V with i5 2500K (Bios is latest as of this week)
Artic Freezer 7 CPU Cooler
6gb Corsair XMS3 DDR3 1600,
Asus Radeon HD6850 1gb,
2x WD Caviar Black 640gb RAID 1,
1 x Samsung F3 1tb,
2 x samsung 250gb HD,
Creative Audigy PCI Sound card, Corsair TX650w PSU,
Plextor SATA DVD/RW.
Win 7 x64

System would randomly lockup. Unable to overclock using AI Suite - would reboot 5-6 times and then lockup. All components are seated correctly.
It seems RAID 1 is not really supported on this board, certainly not with WD Blacks (which are not great for RAID according to some other forums). I have now removed the RAID array and also rebuilt the system. Seems to be relatively stable, although the CPU FAN RPM is not correctly reported by the BIOS (though this is a common theme with Freezer 7 and Asus boards supposedly). Am still not fully conviced and think its more than likely down to a new chipset and an immature BIOS which needs a LOT of work to become a decent and stable good board.

I wish I'd stuck with my Core2Duo Gigabyte board which was rock solid and had no issues with my RAID array or overclocking.

AND - I don't care what people say, the new BIOS is not all that. Yes you can use a mouse on it, great. its still not very good for trouble shooting - just my opinion

All in all, quite disappointed with the whole experience and if I get any more issues, might just send the POS back and get another manufacturers board.
November 19, 2011 7:49:48 PM

600w should be enough to run your system, unless it is faulty.

I recently built a system with the Asus P8Z68-V Pro/Gen3, which came with the latest bios on the disc. So far, I have had no issues with the board, the software, or hardware incompatibility.

Here are my specs:
Intel i7 2600K @ 4.2
Asus So. 1155 P8Z68-v pro/Gen3
16GB(4x4GB)Corsair Vengeance blue 1600Mhz DDR3 RAM 1600Mhz @1.5v
HAF X RC-942 black full sized tower with window
Corsair HX1050 1050w PSU
1x 240GB OCZ Vertex 3 Sata 600
1x 1TB WD CaviarBlack WD1002FAEX
LG SuperMulti Blue BH10LS30
Corsair H80 liquid cooler
Scythe Kaze Master Pro fan control KM03-BK
1x MSI n580GTX Lightning(soon to be sli)
Windows 7 Ultimate 64 Bit

So far, the best answers, I see, are from AGuru and developeraslam

Anyway, what most of you are experiencing is a deep hibernation, which is an energy saving feature of the board. It is similar to a regular hibernation, but saves more power. It seems like the system is shut down, but it isn't. I, initially, thought my system was off, because when I tapped the keyboard keys or (only)moved the mouse nothing happened, but when I pressed the mouse button or pressed the power switch, the system turned on and was exactly how I left it(midway through a film in the internet), and did not need to boot up. So, the new bios is waking my board up correctly. Unfortunately, some boards with the older Bios version don't wake up. The new bios should correct some of those issues. There is one more thing that you should know. This isn't purely a mainboard problem, Windows 64bit systems are seeing a lot of this, regardless of mainboard. The Problem is that Windows Vista and 7 64bit are not optimized for hibernation/deep hibernation, and some of windows default settings allow your computer to sleep even though you are using it. One common example is within the multimedia settings. You could be watching a film in the internet or on DVD, but because you aren't touching keys, the computer will go into sleep mode. That can be changed along with other advanced power settings, if necessary. Anyway, Microsoft claimed that they improved on this issue before releasing Windows 7, but it turns out that they didn't.
The 1600Mhz RAM is set by default at 1333Mhz, because Sandy Bridge processors were originally tested to run with RAM up to and including that speed. Other speeds were added/tested later. If you go to the specifications on the Intel website, you still see 1333Mhz as the highest speed tested, or at least that's what was posted, when I last looked. If you go to Corsair, you'll see a way too brief warning of the RAM speeds. Plus, they tell you which kits they have tested to run with SB. Your kit is on the list of compatible RAM. So, unless it's damaged/faulty, or with some boards in the wrong slots, it should work. According to this manual, you should be placing the RAM(from left to right) in the 2nd and 4th slots. Asus has a few helpful hints and explanations geared towards choosing the right components and troubleshooting on their website and in the manual.
Also, you should press firmly and evenly, but not roughly, on the RAM to lock it into place, and take care not to push it in on an angle. Once properly in place the lock should close.

Also, as the person above correctly mentioned, the LED lights and the beeps do let you know what is failing. Check your manual, double check all connections, look at the lights again when you boot up, listen to the beeps, and make sure that you didn't accidentally enable/disable one of the switches on the board.

As far as raid goes, western digital made a raid version of it's harddrives, which is more expensive, but supposedly, functions better in a raid set up.

I used AI Tweaker for my OC. I didn't experience any problems. It basically does everything for you.

Next.This may not actually be the problem, but since you asked. The cmos clear jumper is a little cap that goes over 2 out of three pins. Depending on which two pins you are covering, you will either be in normal(default) or in clear rtc. That cover is important. If you look in the contents in your manual under "motherboard overview" where it says "jumper", you'll find the page that will show you where it is and how it works. My v pro manual says page 2-20.

*** UPDATE *** - After getting a new board and still getting the same issues, i deemed it as either a CPU (doubtful), Memory (Possible), or another hardware issue. I did a memcheckx86 test on my RAM and found 1 of the sticks to be bad. I used the remaining sticks and set to XMP and it was stable as... so lesson learned... CHECK YOUR MEMORY!
January 16, 2012 7:15:44 PM

I got a new ASUS P8Z68-V Pro/gen 3 motherboard, I7-2600K and 16GB Corsair vengeance 1600mhz and had BIG problems.

Could get Windows 7 64 installed, but post install it would crash repeatedly. To add insult to injury it would "take out" all the driver i installed.

Eventually i found out i made a mistake. I did not know what TPU and EPU switches were and reading the (poorly translated) manual, had turned them BOTH on before installing the OS.

Once i realised that both being on was asking for trouble by trying to get the motherboard to both sprint and use less power at the same time, i switched them BOTH off.

Since then, no problems with installing anything and the system (so far) remains stable. Now i have it stable i can start trying things out such as the TPU and EPU and all the other things on the BIOS..

HOWEVER, one issue - where can i get a case that will support motherboard, 6 SATA leads (I have 4 hard drives and 2 DVD drives) without all of the cabled being crushed into the internal hard drive caddies? I have to leave the case "half open" to be able to use the motherboard.
February 4, 2012 1:06:20 AM

I just bough a ASUS P8Z68-V gen 3 motherboard with an Intel I5 2500, Hyper X 2x4048 megs 1600mhz DDR3, 700 W Power supply, ect... Set it all up, carefully following all the instructions, then, finally plug it in, turn on the power supply,,, the light turns on, the fans starts,,,, and then stops. turn on, and stops, turns on, and stops, again and again and again. Brought it back at the store so they tested it with different processors, power supply, memory and nothing, have to send it back to Asus to the States and I have to wait a couple of weeks at lease for my brend new machine god them it. Hope I wont have any more problems afterward.
February 10, 2012 1:16:58 AM

Just wanted to add my two cents here. I had similar issues to the initial poster. Put together my machine and plugged it in and it worked without an issue. Did a little overclocking, installed Win7, updated to latest drivers and finally did a few hours of stability testing. Upon shutdown, the system wouldn't reboot without removing the PSU plug, allowing for discharge of the MB and then plugging it back it. The system would then restart, but got the F1 screen upon reboot and then the BIOS was back to default settings. After searching the web and noticing that multiple people were having similar issues, but no concrete answers, I thought I'd make a post with my solution.

Not sure if this will be everyones problem, but I went over my MB and realized that the Clear RTM RAM jumper was missing. (Page 2-20 of the manual). Looks like the MB just came without it for some reason (hooray for ASUS inspectors). What was happening was that without the jumper, the system wouldn't reboot. So I went to one of my old HD's just laying around, removed the jumper and added to my MB (covering the first two pins left to right). Boom, system works without a hitch. Required no BIOS update or BIOS tweeks. Hope this helps.

I was also having problems with the system refusing to post. I have an ASUS P8Z-68-V LX with an Intel core 5 2500K. All the problems described in this thread I also experienced. Finally it posted with one 4GB memory module (Kingston KHX 1333C9D3B1K). I finished loading Windows 7 64 bit and updated everything-drivers BIOS etc. I noted in the BIOS the memory was running at 867 MHz though the DDR3 is rated at 1333 MHz. I changed the BIOS setting to 1333 MHz saved it and restarted the computer. It would not post again. I restarted again and it did post. I went in and changed the setting back to 867 MHz and the system booted again with no problem.

I shut down again and plugged in the other memory module running at 867 MHz and the system booted with no problem. I am currently running with both the modules as 867GHz and everything is working fine-the system is recognizing 8 GB. It's not where it is supposed to be but I am leaving it alone for now because I am sick of ****ing around with it.

I would like to add 2 cents to expand on thepedro777's ideas.

It seems (i.e., check it out yourself) that with these ASUS mobo and UEFI and overclocking/turbo mode, each level must be the same.

What I mean is: I had the system on "Green, power saving mode" in the Simple UEFI/BIOS. I accidentally hit the ASUS overclocking system (in Win7) and it went to 4.4 GHz but it was unstable after a while. It seems that you can't [?] have power-saving and overclocking at the same time. Of course. But you have to remember. Similarly, you can't have the TPU and EPU switches ON in the motherboard at the same time. I imagine that you can't have the EPU switch ON and then try to OC in the BIOS. Or TPU switch ON and then set "energy saving in UEFI. And if you have the system OC for you, that takes the Advanced BIOS out of XMP mode if you decide to reset to normal (that middle option in the Basic UEFI initial screen).

So hardware, UEFI, and software all have to match or you will have problems.

Just wanted to document this for other newbies like myself.


Also, I have found that you may have to repeat the reset CMOS with the CLRTC a couple of times, as well as re-seat the memory (esp new). FYI.

I just purchased two P8-68-V/GEN3's and two Intel core i5's. One for my wife and one for myself. I can not get either one to load up windows. Am I wrong in assuming that it should have been a simple plug and play then install drivers like all my past Motherboard/cpu changes? Or should/will I have to put my old hardware back in. Back up my files on the external. And then install the new stuff with a reformatted drive/fresh copy of windows 7 64bit?

Any help would be greatly appreciated because ASUStek was unable to provide any insight. Having just spent near $900 up here in Alaska. I would love for them to work :) 

Thank you in advance.

Reinstall Windows from afresh on both machines. If you encounter any issues doing that, then list all parts used and the configuration and we can take a look.

Following up from my Last post regarding my setup -

Asus P8Z68-V
Kingston HyperX 8gb RAM (1600)
Corsair TX-650w PSU
OCS Agility 3 120gb SSD
Asus Radeon 6850 1gb
DVD-RW
2 x WD BLACK 1tb HD
1 x Samsung F3 1tb HD

This was running sweet for over 3 months with no overclock, latest bios etc. Powered the machine off after using it, came back home the next day hit the power button - no output on the screen. Thought it was odd, so powered down tried it again - same result.
Opened up the case, and checked the LEDs onboard to see which one lit when booting - it was the BOOT_DEVICE_LED. I unplugged all drives, tried it again - same result. Unplugged GPU - same result. Took 1 stick of RAM out - same result. Reset BIOS using jumper and removed Battery - got the ASUS splash screen when booted, but then hung (and BOOT_DEVICE_LED) was lit - and there were NO SATA devices plugged in!!!!

I'll be honest, i'm fed up with ASUS. I've had so many problems with the Z68 boards and so have sent it back to the supplier (Ebuyer) who have been extremely good (so far) and said to me i can get a different manufacturers board IF mine does turn out to be faulty.

I'm currently waiting for them to confirm its faulty and send me a Gigabyte board - have had them in the past with NO issues.

Whats odd is that ALL the review sites rate these boards highly - I think they maybe are good, but i'm seeing more and more posts on different forums stating a significant amount of component failures on these recent ASUS motherboards and i'm beginning to think that maybe ASUS need to look at the QS potentially.

It would be good to have these review sites revisit their reviews after say 3-6 months and say which boards are still running and which have died a death!

anyways... i'll post a reply if it turns out to be something other than the board (according to ebuyer).....

My ASUS P8P67 EVO with SB i7-2600K will corrupt my BIOS any time I o/c above 3.9GHz, sleep, and try to wake it up. I have tried different hard drives, reloading the op sys, damn near everything. Since I have an issue with another computer using my Hitachi hard drive(s), I am assuming that they are not spinning up fast enough on wake-up and causing the issue. My other board is an MSI P55-GD65 with an i5-750 and will not wake up above 3GHz but will not corrupt the BIOS.
Make sure to run stock speeds while building the system and make sure it is stable before starting to o/c.
February 28, 2012 8:33:09 AM

UPDATE!: Got a reply back stating that my Asus Z68 board is fine with no issues, so i now think it must be either my memory or CPU. I am waiting for the board to be returned and then i'll rebuild using the same components and see if I still have the issue. To their credit, Ebuyer have said If I do have further issues for me to return all the components (CPU, Memory and Board) and they will see which bit is faulty...

Still a right pain in the ass as I have no working PC!!! ARGHH!!

I am have the same issue with the ASUS P8Z-68-V LX. I am trying to install Hyper X 4x4048 megs 1600mhz DDR3.

I have successfully installed Windows 7 with 8 gigs in slot B1, B2. System runs great, but It seems that when putting anything in slots A1, A2 I don't even get the POST. I sure would love to utilize all four slots and the 16GB of RAM. But for the life of me i cannot figure out the issue.

This seems to be a very common problem with this MB, and somebody by now has to have found a fix for this?

I have seen that problem posted before on this site. I believe it had something to do with using the default XMP settings. Yes?

FYI , and good luck with the search. Hey. Paste a link here when you find the answer.

I just changed the BIOS settings to run X.M.P default. This did change the RAM in slots B1, and B2 to run at the correct speed 1600mhz over the 1300mhz it was running. But still nothing when filling slots A1 or A2.

Can't get the POST to even enter the BIOS settings when these two slots are filled. I hope I don't have to go through the hassle of getting this board replaced. Seems to be a pretty common issue and I'm sure there is a simple solution, just have not found it yet...

It was my impression that you CAN'T use XMP mode with all 4 slots.

A guess? Don't use XMP in bios but set those values; e.g., volts at 1.500 et cetera.

Sorry for the idle speculation. I'll look, too, for that post.
March 4, 2012 12:07:52 PM

Ah, well either way I first tried occupying all four slots when it was on Auto and not XMP mode and ran into the same exact issue. Soon as I took the RAM out of slots A1, A2 Windows 7 64bit booted up fine with 8gb in slots B1, B2. Suppose I could go set those value's myself once I finish waking up here.


Quote:

Try different combinations of each one of those DIMM in a single slot to see if it is a memory stick or a slot.

Its odd that you say your memory is in slots B1 and B2. On my Pro/Gen3, you are supposed to fill the first two slots in A2 and B2, otherwise it won;t work in dual channel mode. I'd double check your manual.

BTW, to the OP, the BIOS will say "Overclock failed" whenever power is cut when the BIOS is starting up. The BIOS has no way of telling whether a power failure occurred or the system reset because of a failed overclock.


And yes, I know Geno. This was my original issue when I recently setup this build. It just wouldn't work in the original slots A2, B2, like the Manual said. The only way I could get the system to work was in B1, and B2.

I have tried many different combination's and all sticks of RAM run perfectly find If I do not stick them in slots A1, A2 as if those slots are just bad.

I am really hoping that is not the issue and there's a fix for it, before I drive 1 hour to the Microcenter to return the MB.

Hello, did you ever find a resolution to this problem? I have the exact same issue (same exact hardware). I can't get my machine to POST with one DIMM in either A1 or A2. It only will POST with a DIMM in B1 and B2.

I got this motherboard as open box from Micro Center this past weekend. I thought perhaps that this was why it was returned.

Interesting that we both have purchased are's from Micro Center. But no, I have not yet resolved this issue. There is one more thing I am going to try tonight. But as far as I am concerned A1, A2 slots are commonly faulty on this board. .

I will let you know tonight when I tinker with it a bit more. Honestly, I have my doubts. Considering Micro Center has pretty good return policies and shouldn't have a problem, even though it will be a hassle for me. Also I don't want to loose any of the features this MB has for anther one.

Also don't really have the time to contact Asus about this, I have scanned search engines, forums, and Asus support forum for a solution without any luck.
March 5, 2012 1:15:26 PM

Thanks for the reply.

Yes it is interesting. I thought in a strange way, that I picked up the motherboard you returned. :D  Then I noticed the date of your post.

Looks like I have to plan another hour commute to Micro Center this week in VA. I want to keep the MB for the same reasons. I especially like their UEFI implementation, so it's a keeper.

The problem that you described has happened to me also, and I found an easy fix. First of all you have to be sure that all your hardware is mounted and connected as it should be. So motherbord mounted on all 9 stand-off, with a washer between the screw and the motherboard. RAM is seated correctly and all the powercables from the PSU are fitted to the motherboard correctly. If all that is fine, then maybe you have one of the two the following issues:

1.
If all the settings in the BIOS are at default, the processor is slightly overclocked by default. Sometimes a processor can't handle the overclock and fails the POST at boot. That's why you get the message: Overclocking failed. To resolve this problem go into the bios and adjust all the relevant settings to standard, or manual with the correct setting for your processor. Do not use the auto settings. ASUS support can help you with this.

2.
Maybe the processor is not seated correctly on the motherboard, or a aftermarket cooler is placed in the system without a proper (or properly mounted) backplate. In this case the processor does not make a good enough contact with the socket, resulting in either a 'Overclocking failed' or 'new cpu installed'message on reboot.

I hope this helps to solve your problem. I'm using the same motherboard myself (on bios 3201 at this moment) and it has been rock-stable and without any issues op till now. And by the way, I use a 600Watt PSU myself, and that is more then enough for your setup, cause my setup has more power-hungry hardware installed and is running fine. (assuming you use a decent PSU).

I have the Kingston Hyper X installed (KHX1600C9D3P1K2/8G) its the Plug N Play version (that supposedly mirrors whatever the board is running). This memory is on the QVL for the ASUS board.
I have 4 x 4gb populated across all 4 slots obviously with no issues.

This board is very sensitive to memory... so make sure the RAM you're buying is on the latest QVL from their website.
March 11, 2012 10:20:13 AM

UPDATE on my own "issues"

So Board was returned as "No Fault Found". Installed it again in the PC and it booted fine with "new processor found".
Strangely the BOOT_DEVICE_LED is still lit, but it posts and boots through to windows.
I found that as soon as I plugged in the Powered USB2 hub i have, it stopped the board from posting or even working. If I plug in the USB Hub without its own power, the PC boots fine. So conclusion is that it won't take Powered USB hubs.
I am slightly confused in that before i sent it back, i pulled EVERYTHING out of the back of the machine and internall and it still wouldn't boot, so I can only assume they did a full BIOS reset and this fixed it.

Anyways, am still not 100% convinced with the board, but its running sweet at the mo, so am relatively happy!

They probably pulled out the CPU and checkec the LANs.

Maybe there is something wrong with your specific USB Hub.



You're potentially right... its a bit old now.. so might invest in a new one. Just odd about the BOOT_DEVICE_LED being on all the time...

Anyways, its working at the moment (long may it continue), but buying an ASUS board has left a bit of a sour taste in my mouth - just a shame I can't afford to buy another board :(

Glad it's working for you. We have the same motherboard and memory. I didn't try a full BIOS reset, but I did update the BIOS and it still didn't boot with memory in those two slots.

I was able to return the open box item for a new motherboard of the same model.

This worked right out of box as I powered it up using the two memory slots. So, I'm happy now.
