Hey guys.

I have 2 x GTX 780s under water, and overclocked to 1198mhz on the cores and 3460 on the VRAM.

REcently I have noticed that when I game for a while then come out of a game, occasionally I get glitches in Chrome.

It looks like a VRAM issue, but running heaven and skyrim heavily modded so both cards are running full chatt. There is never any problem in the game.

I thought maybe that the VRAM speed is dropping too much after a game closes, thus causing the GFX to become unstable.

If so, how can I stop this from happening. I don't think my cards are faulty as in games, and benchmarks I'm not seeing any problems.

Here is an example of what I get afterwards.



I only get this after my cards have been running in a game I think (not noticed it other wise) any ideas if their is any way to reduce amount my VRAM is dropping after I close any 3D apps. (games and benchies).

If I reboot then the problem goes away and I've not seen it again until I have gamed again, then closed the game down.....
 
I doubt very much that its a issue with VRAM mate, I think its more of a driver/chrome issue then anything else...

Well I thought that too Stelly, but I upgraded to latest NVidia BETA driver tonight, seeing if that would fix it but it hasn't. The BETA driver came out yesterday.

I did get this also earlier tonight before I upgraded to new BETA drivers.



That is not in chrome.
 
Okay, well I had an issue with SLi under Windows 7 mate, I tried an amazing amount of drivers, different SLi bridge and everything. What sorted it out was going to Windows 8.1 mate, that sorted the issue, if it was corruption with VRAM I though it would have been more random mate :)

Stelly
 
Well I have Windows 8.1 already.

I ahve installed nv inspector and set the P8 state to increase the mins VRAM speed from the default of 325mhz to 508mhz.

I will try that and see how I get on... the glitches dont happen all the time, so it maybe tomorrow before I see any glitches, plus CBA gaming for any more tonight.
 
hmmmmm

I unplugged my second GPU ran skyrim for an hour, came out. Windows functioning 100% fine for 3 hrs.

So put the 2nd card back in, and even tried a new SLI bridge connector. Anyway played skyrim for a couple of hours. Worked flawlessly. Closed skyrim. Within 2mins this....



I'm 99% sure my 2nd card is faulty.

I'm going to remove my primary card, and try running my PC with just my secondary card in now.

BRB!
 
Well its booted up fine now with my secondary card only plugged in, gunna try a bit of gaming and see if I get the glitches afterwards
 
If the second card is found to be fine, I would use Display Driver Uninstaller in safe mode, completely remove the drivers and restart. Install the latest Beta drivers and see if it still does it.

I was having a nightmare last night/today where any game would BSOD after 5/10 mins and I couldn't figure it out but a complete clean install of the drivers has cured it for me. A possible corruption of older drivers is most likely the cause and DDU cleared them out.
 
Well interestingly no problems running only my secondary card as well now.

So I think you maybe rigth that driver problem may have caused this, but only issues after SLI has been used in games.

I just ran DDU and found a mixture of driver versions and strangely 3 GPU's found - at the time only 1 was plugged in.



Anyway I've removed the drivers now, reinstalled both cards and downloaded and installed the lastest drivers again (was the ones I was on anyway) Hoepfully this will resolve my issues.
 
Fingers crossed :) and it was the latest drivers causing me grief but after clean re-installing, they have been superb. BF4 is fantastically smooth and seems to have a few more fps.
 
hmmm, well I have had an hour on Skyrim, come out and noticed no glitches. they would have happened by now.

However I think I know 1 other thing that may have been causing it...
The END mod for skyrim the author suggests keeping v-snyc disabled for some reason, I had it enabled in the Nvidia control panel, overwriting the mod disabling it.

That could have caused the glitch issues. TBH the only game I tried was skyrim.
 
OH really?




Anyway, seems that my problem is fixed now, so thank god it wasnt a hardware problem. Damn drivers.!
