Hi,

It look like realbench crash my nvidia video driver when I stop the stress test after more than 10mins. I could run the test for hours without issues but as soon as I try to stop it the screen goes blank and I need to force reset my pc. I can run prime95 and uninige heaven for two hours no problem and it never crashed when I stopped them.

It does the same thing with default oc setting on my gpu. Is this a bug with realbench ? has anyone else have the same problem ?

Could it be an issue with sli ? I did not try it with sli disable.

I'd like to find the answer to this question as well. My hardware includes a Rampage V Extreme board, 5960x and 2x ASUS GTX 980 Ti Strix GPU's in SLI. Im suffering from the exact same issue and am having to avoid realbench for the time being. Came here looking to make a post on this very subject.

I have the same exact issue:

6700k
Maximus VIII Hero
980 Ti SLI

Crashes/screen goes black every time regardless of the duration of the test. I do believe it's related to SLI though as when I disabled it, everything was fine. Hopefully they fix this soon, but I think we can at least rest assured it's not a stability issue with our systems.

That's good to know. Thanks for your answer.

same issue. 6700k and 980 Ti SLI. was stress testing for about 5 hrs yesterday and another 6 or so today. both times i came back to a black screen. have another intermittent issue where luxmark crashes. everything else (desktop, handbrake test) is running fine. i decided that after running ok for a total of 11 hrs that my 4.6 overclock is rock solid. realbench? not so much...

I have the same problem. is this something that I should worry about?
Sometimes the PC reboots itself when the test stops after hours of testing. Is this something that I should investigate?

If your system crashes or reboots during or after then it is a stability issue, whether you should worry is up to you, if your system is stable in your daily use is more important than if its stable running stress test unless you run stress tests and benchmarks most the time.
Black screens are probably driver related, if you are running the benchmark to compare your scores against others you don't need to run your cards in sli, Relbench uses all your graphics cards regardless if there in a sli or crossfire setup or not

Just to be clear, it always crashes when you stop the test and you have SLI enabled and occasionally the crash is a
reboot instead of a black screen? If you haven't already, use other stability tests to test your system. If RealBench
is the only one to have issues with, then whether or not you should investigate more depends on how sure you
want to be that it's not just a glitch in RealBench.

...or then there just might be iffy code in RealBench. The fact that this happens when people are stopping the
stress test and not running the benchmark seems odd. If it was a driver issue, one would not (as a first guess)
expect the test crash when starting instead when the system is supposed to return to its normal desktop state.

Is everyone experiencing SLI issues using the newest NVIDIA drivers? Post your driver version, maybe someone
can narrow the problem down even more.

Looks like this problem hasn't been fixed. I run a SLI setup and I have the exact same problem - everything works fine until I stop or the time runs out for the stress test. Too bad, I really like the program but as of now I will have to use something else.

in my case disabling SLI while testing help.
in any case video rendering will not use SLI but will use the cards separately so SLI is of no use there.
try disabling SLI and retry.

I think i had encountered this issue aswell, im not 100% sure.

I did a stress test for about 15minutes and after the last seconds were ticking away my screen went into a blackscreen and kept that way until i rebooted it.

Think it might be a instability issue with my overclock.

I don't think so.
With some drivers I had this problem without oc also on a rock solid system.
Try to diaable SLI if you have it, on my rig it helped a lot.

I'm having the same issue, as soon as i stop real bench (stress test) it freezes and then black screen. Sometimes if i wait a while it will come back to windows but says nvidia driver has stopped. I can run the stress test for +1hrs with out issues.
I have Maximus viii extreme, 6700k and strix 980 ti SLI.

It is entirely possible to be completely stable at load and then unstable when dropping from load to idle, which is what happens when the stress test stops. I believe that is what vdroop is supposed to help with, which is affected by your Load Line Calibration setting. If I have understood it properly (and I may not have), lower LLC settings may decrease stability at load but would help stability when dropping from load to idle.

I'm having this issue as well tried all three latest versions of Realbench and it seldom if ever gives a blue screen. Just crashes the video driver when I either stop the test or it finishes.

I can pass the stress Aida test without problems when i tell it to stress everything except the hard drives.

I can confirm that this is indeed related to SLI in some way, As I recently posted in my thread here on these forums, my system finishes the test fine without SLI enabled but as soon as I enable it, it crashes realbench AT THE EXACT time the test ends or I manually stop it. To make sure it was an accurate test I performed this on known good Nvidia drivers 362) and on a CLEAN install of Windows 10 x64 pro.

Tonight I am going to try it on a clean install of Windows 10 and I will check the results!

Yeh.. pretty much sure it is some SLI related bug with Realbench.

Have exactly the same issue and have been testing for a month with my new build.

I can run for 12Hrs plus with no issue but as soon as it is stopped manually it will crash. I can even just run it for say 2 mins and it does the same.

It does not seem related to stability as I can downclock my cards and keep the voltage up and it behaves exactly the same. Disable SLI and it does not crash.

...and it only crashes on exit not while actually benching.

Ugh, I think I have this now too. Problem is disabling SLI isn't fixing it. It usually, but not always, crashes on me during the "Gathering System Info" bit at the end of a run. From WhoCrashed, I get this:

On Tue 5/24/2016 2:54:55 AM GMT your computer crashed
crash dump file: C:\Windows\Minidump\052316-15812-01.dmp
This was probably caused by the following module: cpuz138_x64.sys (cpuz138_x64+0x2084)
Bugcheck code: 0xA (0x14DCE8, 0xF, 0x1, 0xFFFFF802BB9F9197)
Error: IRQL_NOT_LESS_OR_EQUAL
Bug check description: This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: cpuz138_x64.sys .
Google query: cpuz138_x64.sys IRQL_NOT_LESS_OR_EQUAL

Did some googling and apparently some version of Speccy were causing crashes, and Speccy uses the same cpuz138_x64.sys.

At any rate, this OC has passed 8 hours Aida, 8 hours OCCT 4.4.2, and 1350% HCI Memtest. No crashing in games either, though I'm not running any very recent ones. Realbench is the only thing finding instability at this point, which makes me wonder if it's not something in the program.

I'm going to try running BIOS at defaults and seeing if I can reproduce the crashes.

EDIT: With all optimized defaults except for disabled CSM (not even XMP memory), and GPU's set to factory settings, it only took about 4 tries to crash my system (black screen except for blinking cursor) by moving the mouse to interrupt the OpenCL test. I did have SLI enabled, for the record. There's definitely *something* wrong.

Now to restore a backup I made earlier today, must've crashed like 20 times via Realbench.

OMG! I have been trying to stablize my system because everytime I ran the test, it would reboot at the END of the test. Glad I googled it.

After reading this, disable my SLI, it doesn't crash anymore.... been at this for hours and hours thinking it was stability issues
Didn't crash for 4hrs on OCCT: CPU or LinPack, or AIDA64. Should have none it was the GPUs, since I didn't use them to stress GPU. I don't have my GPUs OC either all stock.
I running 2x Titan XP + 1 980TI with 372.70 drivers.

On my system clicking stop on Realbench while stress testing will result in a blue screen and system restart (this happens with loaded optimized settings). Turning off SLI seems to have stopped this error from occurring.
