RAM or Mobo faulty?

This is my first build and when I turn my comp on all fans turn on but it never finishes. First I got beeps indicating no RAM, so I reseated it and that went away. However, then it beeped that there was faulty hardware and Boot Device LED stayed on. I decided to go through the "PREFORM THESE STEPS" sticky and got all the way to number 6. While cycling through the RAM I put them in slot A2. For stick 1-3 MemOK LED light stays red and I get 1 continuous beep and two short beeps indicating memory not detected. For stick 4 the MemOK LED light stays red but there is no beeps. I am a noob and have no clue what this means. Why will it move on with 4 sticks in but not 1?

Here are my specs:

CPU Intel Core i7-2600K Sandy Bridge
Optical Drive LITE-ON Black SATA DVD-ROM Drive
HDD Seagate Barracuda ST1000DM003 1TB 7200 RPM SATA 6.0Gb/s 3.5"
GPU XFX Double D Black Edition FX-795A-TDBC Radeon HD 7950
CPU Cooler CORSAIR H100
SSD OCZ Agility 3 AGT3-25SAT3-120G 2.5" 120GB SATA III
PSU OCZ ZX Series 850W Fully-Modular 80PLUS Gold
RAM CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
Mobo ASUS P8Z68-V/GEN3 LGA 1155 Intel Z68
Case COOLER MASTER HAF 932

Sounds to me like you have at least 1 bad stick of RAM or at least 1 bad RAM slot.

There is no easy way to tell which is which. You would just have to try different sticks and different slots until you found a combination that will boot with no errors.

Then you could try other sticks in that slot and that same stick in other slots to figure out which slots and sticks were good or bad.

Ok I have tried each stick in each slot:

Stick 1 No beep in A1, Beeps in A2, B1, B2
Stick 2 Beeps in A1, A2, B1, B2
Stick 3 Beeps in A1, A2, B1, B2
Stick 4No beep in A1 and A2, Beeps in B1 and B2

MemOK LED stayed on for all trials.
Beeps are the 1 constant followed by 2 short beeps.

So your saying it works fine with all 4 sticks installed, but not with just 1 installed?

Before I posted, when all 4 were in it got past checking the RAM and gave me a short beep, and after about 5 seconds 1 long beep followed by 4 short beeps and the Boot Device LED stayed on. It has never finished setting up. But now with the 4 sticks in it doesn't beep but the MemOK LED stays on, and doesn't proceed.

I haven't used a case speaker in 10yrs so the beeps mean nothing to me, as far as I'm concerned, it either boots or it doesn't.

I think your having a issue with your boot drive or it's hooked up wrong. You have power AND sata cable hooked to the ssd?

Install all 4 sticks and only have the ssd hooked up to SATA 1(see manual), do not hook up the other hdd. Then put your windows dvd in the drive, reboot and go in bios. Select the dvd drive as the 1st boot device and boot to your windows disk.

I did that and MemOK LED still stayed on and I got one long beep followed by 2 short beeps (repeated). The mobo manual says that means no memory is detected.

Are you sure the ram is pushed all the way in and the tabs are locked?

I'd try different memory.

I find 8 different sets of DDR3-1600 4x4GB Vengeance listed on Newegg. Which model do you have? Is it on the mobo qvl?

Model CMZ16GX3M4A1600C9

I just rechecked and all RAM is pushed in and tabs down. And no that model for CORSAIR is not on the mobo qvl.

What happens when Stick 1 is in A1 and Stick 4 is in A2, with nothing in the other 2?

1 constant beep and 2 short beeps repeated. I don't know why it is being so inconsistent with its beeps but the MemOK LED always stays lit when I try whether there are beeps or not.

Take out the battery for 30 min and put it back in and just leave the 1 in slot A1 in there and take the other one back out. Push hard on the one in A1. Put the battery back in after 30 min and try to turn it on and see what happens.

By battery you mean the power supply right? I'll post results

No, I don't mean the power supply, I mean the battery.

- Edit - Looks like this http://www.infobarrel.com/media/image/5051.jpg

It is a regular CR 2032 watch battery. Small round thing between the processor and the first PCIE slot on most motherboards.

It allows the computer to retain its configuration master list that enables faster booting.

If you take out the battery for 30 minutes it will forget the contents of the configuration master list.

When you turn the computer on, it will be forced to rebuild the contents from scratch.

If there is an error in the configuration master list, it would be erased by this rebuilding process.

There is a little plate on the side of the slot, if you push on that with something like a screw driver the battery will be ejected.

You will want to try to push it towards the circular wall as much as possible rather than using downward force to make sure you don't damage the plate.

5 min should be more than enough.

Removed battery for 30 minutes and left only the one stick in slot A1. Same beeps and MemOK LED on. Tried slot A2 also since mobo prefers that configuration and got same results.

The Corsair RAM with Part number CMZ16GX3M4A1600C9 should be quite similar to one that is on the QVL CMZ8GX3M2A1600C9. I am guessing the 8 vs the 16 are total megs of RAM and the 4 vs the 2 are total number of sticks in the package. Those values line up conveniently well.

Is there any way you could upload some photos of what the inside of the computer looks like just so I can give things a quick glance over?

Or at least just tell me in detail what is plugged in to what?

I am about ready to guess bad board, but it would be nice if some other stuff could be verified first.

Also, as mentioned before is it possible you could borrow a stick of RAM from somebody else?

Please excuse the messy wires; I have been messing with this darn thing all day!

I am looking at the pictures, is there any reason the OCZ intake fan faces upwards instead of down?

- Edit - BTW, do you have the CD drive in the lowest possible slot?

Because of the fan grill the screws for the PSU don't match up with the screw holes on the case :/  I would like to put it upside down and I was afraid to take the fan grill off. The CD drive is actually in the highest available slot lol, should I change that?

It just looked to me like a bunch of wires were going into the bottom 5.25 slot and I was wondering if I was just seeing things or if it really was up there.

That being said, I would suggest it be in the 2nd slot from the top ideally. The top of the case is where the greatest amount of heat is and if you don't need something there its best not to have it there.

I would be a lot more worried about the fan being pointed up on the PSU more than the CD drive stuff though. That potentially messes up airflow inside the case to say nothing of the risk of something physically falling into the PSU.

Ok I'll make those fixes. But for the PSU should I remove the fan grill and mount it, or just let it sit (there is a vent on the bottom of the case) unmounted and be careful when moving? Thanks for all your help! I'm having some friends come over to take a look at my comp and root out the problem. I'll post in the thread the fix for anyone who may have the same symptoms.

If it can't be secured any other way just leave it I guess, but I think you might want to look for a different sort of PSU next time you need to buy one.
