Windows 7 Occasional ntoskrnl BSOD

I've been battling this one since I built this system in late October. Since then, the machine suffers a BSOD, approximately once every two days; although it has gone as long as nine days in between.

There is no obvious theme to what the machine is doing when the crash occurs. It has crashed at idle, in graphics intensive games, and while simply browsing the internet.

I've done what I feel I can, and now must seek your assistance.

The machine is running Windows 7 x64 Pro.

I began by using WhoCrashed 2.10 to analyze the minidumps after the first BSOD.

Sadly, all 22 dumps I've collected list ntoskrnl.exe as the cause, although for varying reasons; including 'CRITICAL STRUCTURE CORRUPTION' and 'KMODE EXCEPTION NOT HANDLED'.

I have run Memtest86+ to completion, with my RAM modules in their current positions.
I have NOT run Memtest86+ on the modules individually.

I have reinstalled several drivers, and I believe them all to be current.

I have attached my latest three minidumps.

The single most recent dump was created while 'verifer.exe' was active, monitoring all non-Microsoft drivers on the system; and running all tests except 'Low Resource Simulation'.

Oddly, after activating the driver verifier, it took a full nine days, and several reboots to actually suffer a BSOD; as opposed to the common two day interval.

I have never installed Alcohol 120% or Daemon Tools on the system.
It was running AVG for a time, but I replaced it with MSE a number of weeks ago.

Thank you for your time.

Welcome.

Ram is set wrong. Load Optimized Defaults in bios, save.

Update Realtek lan driver:

Thank you for the quick response.

Updated the Realtek drivers from 7.00 to 7.34 successfully.

Attempted to alter the RAM settings, however it seems that all settings are already in the 'Auto' mode. There is no universal, 'load optimized defaults' that I can find.

When accessing the memory settings, I'm presented with a list of 30 or so timing items, that I can configure manually, or leave in the automatic mode. I've always left them automatic.

It does seem to me that the timings could be a bit tighter than where the defaults have placed them, but I'm more interested in stability at this point.

Perhaps if you could be more specific as to which RAM settings should be altered?

Thanks again.
 
I've suffered another BSOD after updating the Realtek drivers. I've attached the minidump in the event it might be helpful.

I'm imagining that all there is left to try is to adjust the RAM timings, but I'm not exactly sure in what way they should be changed. Should I underclock the RAM and see if the system stabilizes?

I've also noticed, in my BIOS browsing that the CPU idles around 47 C... which seems a bit high to me, but considering that I'm using the stock cooler, I don't know if I can complain.

Thanks again.

After doing a little more research, I have disabled CPU Spread Spectrum on my motherboard.

My Memory tab now shows:
NB Frequency - 2000.1 MHz
DRAM Frequency - 666.7 MHz

Other timings are the same.

I have no idea if this was necessary, as I am not overclocking the system, but I am running out of ideas, and growing frustrated.
 
Lol, that's why I don't rely much on the verifier, disable it by the way ASAP to stop it crashing you non-stop:


BugCheck 1E, {ffffffffc0000005, fffff80000b9a5b0, 0, 0}
X64_0x1E_c0000005_VRF_Rt64win7+1586b

The network driver is good and latest:
Rt64win7.sys Tue Nov 30 01:01:28 2010

The only driver I'd ask you to update is VIA audio:
viahduaa.sys Thu Sep 17 07:04:15 2009




~~~~~~~~~~~~~~


RAM - it's not set right in the bios, and moreover CPU-Z doesn't detect it right. So I ask you to give link to your memory sticks specs. You can see them on the RAM package if you have it. Then set them right. Loading bios with the optimized defaults can help.

I have upgraded my VIA HD Audio driver.
From: 6.01.7500 Dated: 9/17/2009
To: 6.01.8700 Dated: 8/4/2010


I have altered some of my RAM timings using the information from this datasheet:
Link Removed due to 404 Error

It shows my proper memory timings to be 9-9-9-24.


This is my motherboard:
Link Removed - Invalid URL

My BIOS doesn't have a "Load Optimized Defaults".
I can "Load Defaults", but that simply returns it to the factory settings, which is "Auto" for everything. Obviously, the "Auto" mode is not setting my RAM timings correctly, so I have set them manually.


My New Memory Settings Are:

Memory Clock: 667 MHz DDR3_1333
Memory Controller Mode: Unganged
Power Down Enable: Disabled
Bank Interleaving: Auto
Channel Interleaving: HASH 2

CL: 9
tRCD: 9
tRP: 9
tRAS: 24
tRTP: 5 (Auto)
tRRD: 4 (Auto)
tWTR: 5 (Auto)
tWR: 10 (Auto)
tRC: 33 (Auto) <---{This seems correct, as tRP+tRAS = 33}
tRWTWB: 9 (Auto)
tRWTTO: 8 (Auto)
tWRRD: 2 (Auto)
tWRWR: 3 (Auto)
tRDRD: 4 (Auto)
tRFC0: 110 (Auto)
tRFC1: 110 (Auto)

CHA ADDR/CMD Delay: 22/64 (Auto)
CHA ADDR/CMD Setup: 1 (Auto)
CHA CS/ODT Delay: 0 (Auto)
CHA CS/ODT Setup: 1/2 (Auto)
CHB ADDR/CMD Delay: 22/64 (Auto)
CHB ADDR/CMD Setup: 1 (Auto)
CHB CS/ODT Delay: 0 (Auto)
CHB CS/ODT Setup: 1/2 (Auto)

CHA CKE Drive: 1.50x (Auto)
CHA CS/ODT Drive: 1.50x (Auto)
CHA ADDR/CMD Driver: 1.50x (Auto)
CHA CLK Drive: 1.50x (Auto)
CHA DATA Drive: 1.00x (Auto)
CHA DQS Drive: 1.00x (Auto)
CHA Processor ODT: 60 ohms (Auto)
CHB CKE Drive: 1.50x (Auto)
CHB CS/ODT Drive: 1.50x (Auto)
CHB ADDR/CMD Driver: 1.50x (Auto)
CHB CLK Drive: 1.50x (Auto)
CHB DATA Drive: 1.00x (Auto)
CHB DQS Drive: 1.00x (Auto)
CHB Processor ODT: 60 ohms (Auto)


While I don't know much/anything about the settings I left in the "Auto" state, one thing I wonder about is how the system functioned while tRP was 12 and tRAS was 30. When that was the case, tRC should have been 42... not 33. It was my understanding that having tRC be less than tRP+tRAS was a sure-fire way of preventing a clean boot. Odd.

Nonetheless, I completed another sweep of Memtest86+ last night (before changing the settings). It completed 10 passes in 9.5 hours. Though, with how occasional my problem is, I still can't rule out my RAM. I will run it again tonight.


Also, I have left Driver Verifier running for the time being. It hasn't caused any additional instability. The crashes still average about once per day, usually at very annoying times.


Thank you for the continued support.
 
Your screenshot above shows you have it 665Mhz 9-12-12-30.


The pdf shows it's meant to be DDR3-1333 9-9-9-24 at 1.5V. If this is your RAM set it this way as shown.
 
Sorry, I suppose I should have updated my screenshot after making the timing adjustments. It has been corrected.

Ran Memtest86+ last night with the 9-9-9-24 timings. No problems found in 11 passes.

Yes, your updated screenshots indeed show you have it the right way now 9-9-9-24, and there's your reward - 11 passes without errors. Well done, enjoy the holidays now. : )
 
I wish I had your optimism. The system managed to get through 10 passes with the incorrect RAM timings. Eleven passes with the correct timings doesn't leave me sated.

I just can't trust the system at this point... it ate two months worth of accounting when it crashed during a save operation... (should have had a more recent backup, I know) It also corrupted LibreOffice by crashing during the install operation.

I sincerely hope that either the RAM timings or the updated audio drivers solved the problem.
I'm disabling the driver verifier until the next crash, so that data won't be in the next minidump.

I'll post back when/if it crashes again...

Thank you again for your assistance. You lead me down some avenues I wouldn't have considered otherwise.

Oh yes, it's a well known fact memtest does not necessarily find errors when RAM is set wrong. Sometimes it finds sometimes it doesn't.


Eleven passes with the correct timings doesn't leave me sated.

Still the news is good if the memtest detects no errors, means you have a chance to do without replacing the RAM. So there's probably some grounds for the optimism. Let's hope. : )

I didn't know that Memtest wouldn't necessarily detect off-timing errors.

Thank you. :)
 
Lol, memtest does not always right away detect defective RAM either, even if it's set right and is indeed defective. It takes sometimes to test sticks separately and in different slots.

Thank you. :)

to quote since windows 95 Microsoft have stated about memory testing programs
Defective memory chips may not be detected by memory checking tools. Some memory checking programs are not adequate tests because they do not test RAM in the same way that Windows uses RAM. Most memory checkers use read/write cycles when scanning memory. Since Windows is executing code from memory, it uses execute cycles. Execute cycles are different from read/write cycles and are more vulnerable to parity errors. It is possible for memory checking programs to find parity errors if the memory is extremely faulty.
 
Well, after a week of delightful, crash-free stability, I got up this morning to see something a little odd.

In the past, when the system BSOD'd while I was gone/asleep, I'd usually wake it from sleep, and see the "Windows has recovered from..." message; meaning it had crashed and rebooted itself. Not this time.

This time, I walked into the room and my monitor was in the 'active' state. Essentially, the system was frozen at a black screen. It wouldn't respond to the power button, so a reset was in order. Upon reboot, I found a brand-new minidump waiting for me.

Fine, whatever... off to work.

I come home for lunch, the situation was repeated. Another black screen, another minidump.

Okay... that's enough of this BS. Time for the big guns. People overclock their systems, and verify their stability all the time, right?

So I loaded Prime95. The machine has never run that hot before.

Prime95 runs for 3 hours, 6 minutes. (The usual stability runs are 16+ hours aren't they?)
Thread #3 kicks out the following:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.

So... I'm guessing we can rule out software, and say that I definitely have a hardware problem.

Now what? Am I correct in assuming that it now has to be either motherboard or memory? Could it still be the timings?

Should I take one stick out, run Prime? Then, if it passes, try the other stick? If it fails, try a different slot? Essentially, am I at the point where I need to determine the hardware failure point by process of elimination, or is there another avenue I should attempt first?

Thank you all again.

Yes, this means hardware.

If you've set them right (loaded bios defaults), it's not the timings.

This is the most difficult part, yes you can try that but watch the temps don't let them go past the critical. Stop the test if the CPU reaches or exceeds 70 Celcius Degrees. Cause that way the errors may pop up due to overheating and the testing becomes senseless.


Prime95 - if you do FFT this puts stress primarily on the CPU. Blend tests memory too. You may wanna do both to see if you get different results, hopefully to find out if this is likely your RAM faulty.
