I7 920 overclocking BSOD's thoughts?

I am looking for some thoughts/tips on why I am getting random BSOD's with my current setup. If someone has done overclocking on a setup like this I would like to see what your settings are. I have done a lot of reading on overclocking these processors and put at least 100 hours into this to no avail. Now to really complicate things I have 2 of the exact same systems 1 is running Linux 24/7 and doing Seti with no issues at the same settings. I have run Prime 95 for over 24 hrs on the Windows based system with no errors/warnings. The drivers on the windows based system are all the latest and I keep them up to date.

System Components:
Full tower case (many air mods for better flow and sound deadening) (cables zip tied down)
Thermalright Ultra 120 extreme (2 fans in push/pull) (max temps 72C under full load)
Asus P6T Deluxe V2
Intel i7 920 D stepping
Asus 8800 GTX at factory settings (waiting for a Nvidia 3XX upgrade)
Cooler Master UCP 1100 Watt Power supply
6 X Noiseblocker S series 120mm fans (2 on front of case, 2 on back of case, 2 on CPU)

With all due respect unless I'm missing something it appears that you are overlooking a very fundamental aspect of OC'ing which is that all hardware is not created equal.

I do something very similar to folding in so far as system stress goes and also have identical component i7 systems but they will not operate successfully at the exact same OC settings simply because of manufacturing differences.

You're trying to run a machine at 4Ghz steady and are surprised that you get BSOD's?

Chances are that chip just doesn't want to go that far or some other component of that PC is unhappy with pushing the limits.

Trying backing down a bit and I'll bet you cure your problem.

Thanks for the response but that's not the problem.

And you are certain of this because?

Not being argumentative I just honestly want to know how you arrived at that conclusion since there's no way of you knowing how two different motherboards are going to react to the hardware you stick into them.

Ok, 20 yrs of working with computers, building over 100 and well over 250hrs of testing on this system at anywhere from 2.66G - 4.4G and Prime 95, for one, runs rock stable for 24 hr tests. I have done massive testing on this system with different computer parts. I am not new at this game. I also am not expecting both systems to run at the exact same parameters just because they have the same parts in them. It just so happens that they are at the exact same and run great in Prime 95, memtest86, 3DMark06, ATITool, GPU-Z, CPU-Z.

I'll be curious to see how things play out.

Sounds like you have lots of ability but no matter how many years you put PC's together all it takes is one wonky part in the motherboard that acts up for unknown reasons and with all the components on there it could be quite the challenge to find if it ever gets found.

In any case good luck.

I would have to agree with LoneWolf on this one.

Reply to christop

ahnilated if the systems are truly identical then I know it's a pain but for all the hours you have into it what about swapping the cantankerous motherboard into the linux based system and seeing if it still does the BSOD's?

That might nail it down as a windows issue.

Dunno just tossing ideas out there.

It would be easier to toss another HD in the Windows system and install Linux then move the 2 motherboards. The systems are all zip tied down and a pain to move around.

Im a little confused and have some questions if you wouldnt mind:

1. What other settings have you tried that worked?

2. Is your memory at 1600mhz before the overclock?

3. I would advise you to step down to 1.64 w/ memory voltage to reduce the risk of damage. [:thegreatgrapeape:3]

2. Is your memory at 1600mhz before the overclock? (Yes, it is designed for 1600Mhz 7-7-7-20 at 1.65v but changed to be 1603 when doing the 200 BCLK with timings at 7-7-7-20)

3. I would advise you to step down to 1.64 w/ memory voltage to reduce the risk of damage. [:thegreatgrapeape:3]

( Yeah, I have tried it anywhere from 1.55 - 1.65 (which the MB changes to 1.66))

Well that's what the issue is. At the settings listed above it works great doing Prime 95 for 24hrs + with it using Blend. Now when you run multitasking stuff like Seti/Folding/multiple games it will BSOD at a random time. I have tried changing every setting that I can think of to make it stable.

I tried these settings just as something different and the system won't even boot. I also tried adjusting voltages and no go.

Jumping tp 4.00 GHz is way too much for the 920. I have heard many people say they can do it and probably they can at less than full load but there is no way the 920 can run at max load at 4.00 GHZ without some insane water or extreme cooling... I have found a modest overclock at 3.2 the best.

The C's don't overclock very well, the D's overclock to 4.0 pretty easy. I also am not having a heat problem with the CPU just stability at 4.0 with memory timings at the rated 7-7-7-20.

I had a similar problem with my AMD, I nailed it down to the memory or the HTT link.
I am not sure if the intel stuff has something similar to the HTT link, but I just set my memory and link down to the next lowest frequency.

This is what my pc was doing:

I ran orthos blend for about 8 hours no errors, I then left my pc on for the day only downloading some files. When I returned home from work this pc had rebooted due to a BSOD.
I suspect that the BSOD occurred while decoding some of the files I downloaded.

Later that evening I tested with Prime95 and for some reason it revealed errors on blend, however I did set the priority in the task manager.

Assuming your memory is 1600MHz I don't see that being a problem

After setting the memory and link down my problem was solved.

Perhaps this helps, but I know from experience that computer hardware is like a lucky draw when it comes to overclocking.

Totally wrong.

Well, try this...

Change the IOH and ICH voltage to 1.2

And what voltage is your VTT at? What OS ar you running?

Have you checked your video drivers? Any overclock on video card?

Expecting two computers assembled with the same hardware/settings to operate correctly at stock settings is a given.
To expect that with a almost 50% overclock is silly.
At the very least the two cpu's might not scale clock speed /voltage the same.
Also the ram is being o/c with tight timings.
the 1336 platform, beyond 1066 memory speed is o/c

Nothing abnormal going on here IMO, just have to work and probably increase vcore a little or back off to 3.8 ghz.
Maybe/and or the same with the memory.

1. I changed the IOH and ICH voltage to 1.2 and tests are running on it.

2. The voltages I am running at are in the first post. The OS is Windows 7 professional with all updates.

3. I have the Nvidia 195.62 driver and there is no overclock on the video card and it runs 55C max with the aftermarket cooler on it.

As stated above, I don't expect them to be exactly the same. It just so happens that they both run at the same voltages and settings just one not 100% stable. This is the reason that I have been doing so much testing and adjusting on it. The ram is NOT being overclocked from it's stock settings of 7-7-7-20 at 1600Mhz 1.65 volts. The Corsair kit TR3X6G1600C7 is designed for that speed. The motherboard will take ram speeds up to 2000Mhz and I know this is considered an overclock because they haven't finished the 1600Mhz memory specification. And as I have stated the settings I have for Vcore work fine in Prime95 for 24+ hrs of testing so I don't see where you think this is a problem. I have also tried voltage adjustments as I have stated for the Vcore. Your post doesn't seem very helpful only argumentative.

I agree 100% here. But, when I first built my I7/x58 Combo, I copied one persons bios settings and just started taking down my Vcore, and BOOM it is stable...

So worth a try, I'd say so.

I think thats twice you've said that to advice. Your resisting answers that question your logic, which is flawed.
How do you troubleshoot a problem any other way but to consider possibilities.
The x58 platform chipset is rated to run at memory speeds of 800/1066 above that is considered overclocking. Your ram is rated to run at those speeds.

I can see this is becoming an exercise in futility. If you would know the motherboard you would know what you are saying is based on a flaw.

# Intel LGA1366 Platform
# Intel®X58 chipset
# Triple-channel DDR3 2000(O.C.)/1866(O.C.)/1800(O.C.)/1600(O.C.)/1333/1066 Memory

Now if you look, your statement is wrong about the chipset to begin with. If you would like to continue down this avenue fine, it is not solving the problem in the least. If you would have read what I said, I said I KNOW that the motherboard has no "rated" speed of 1600, it is overclocked. The memory is RATED by Corsair to run stable at 1600 7-7-7-20 1.65volts. You are barking up the wrong tree. I am considering all possibilities, I have tried memory speeds from 1066 - 1900 with this ram and tested it for many hours in memtest86 to have no errors at 1600 which is what it is RATED for.

Ok, so let me get this strait so you dont have to repeat yourself anymore... (lol, i know,sorry) [:jaydeejohn:4]

So your computer is stable when you run prime 95 at the voltages and speeds in the first post, correct?

But then your PC crashes when you run a game or something of the likes, correct?

And could you please post your VTT? Its missing in the first post.

Also can you give the error code received when you get a bsod?

And please, when you overclock, drop the ram ratio to the lowest settings to prevent that as a possibility. (i think thats what everyone is talking about)

Ok trying to stay out of a fight here, so before we travel the same path you have the other posters... Ahnilated, what BSoD hexidecimal code are you getting? This could help us trace down where the failure is. You probably already know this, however you didn't give the information to us so please enlighten us. I'll try and formulate a solution once we have that code. Thank you and sorry for your stress.

Just an update, the system is still running at the 1203Mhz memory clock but this is nothing new. I will keep you all updated.

Nope, didn't work, still locked up on me but no BSOD. I am now going to try shutting off hyperthreading to see if it changes anything.

I dont think this is a cpu problem. Sounds like a video card or HDD problem.

Reply to overshocked

The video card tests fine for 8 hrs no artifacts or errors. The HDD's also test fine. If this was an easy one I wouldn't have bothered you guys here

When its at stock speeds does it crash aswell?

Reply to overshocked

I haven't tried stock speed in a while. Once it finishes 24 hrs with no HT on I will try stock with HT and see if it runs for 24 hrs there.

Reply to ahnilated

Nope, it just locked with HT off. Now for the stock speeds I guess. You want me to put all the voltages at auto overshocked? BTW, if you would like I can give you my email to make this go a bit quicker. I just rebooted that system and I am getting an error on drive 1 of the 3 drive raid array. I am checking this now.

The drive checks good with chkdsk and scandisk. The onboard controller is still showing an error so I am moving all data off of it and will get the drive replaced. Intel's storage manager says some date request errors were received from the first drive. Today is the first time I have seen any errors from the raid but before going on with all the testing I will get this fixed.

Reply to ahnilated

I removed the bad drive and reinstalled the OS. It has been up running tests for the last 24hrs with no errors. We shall see if this keeps going.

Reply to ahnilated

Well that would explain it man....

Reply to overshocked

It didn't fix the problem. I woke up this morning to another BSOD over night.

Reply to ahnilated

have you tried running it off of one drive with a fresh OS install?

Reply to overshocked

Yes, same issue.

Reply to ahnilated

the BSOD error was a bunch of 0's and then 124.

Reply to ahnilated

Just finished memtest86 for 5.5 hrs at 1603Mhz memory speed with no errors at 7-7-7-20 and the processor at 4.0G. Changed video cards to the 8800GTX from the Linux system and I still get the crash. I am starting to think this might be either a motherboard problem or a power supply.
