SLI 460 Blackouts

post #1 of 3
Thread Starter 
First things first, happy new OCN everyone! tongue.gif

Im having some problems with my good ole SLI 460 setup. I've got the latest drivers.

In pretty much any game (BF3, L4D2, Portal2, BFBC2) my screen goes black for about two seconds, my monitors 'no signal' sign comes up for two seconds, then another black screen for two seconds, and if im lucky, it recovers.

I've never seen it recover in BF3 yet.

Could this be an OC failure? I've been using the same OC since some months, but this black screening problem is pretty new.

I bought a SSD and formatted the whole computer, fresh install, still the same issue.

Thanks to some crazy fan profile I made, my temps are never more than 60. (75c in Furmark)

Any ideas?

These are Video TDR Errors, the blackouts are due to the way Windows Vista and Windows 7 check up on your graphics card (to see if its responding) If its "not responding" it attempts to reload the drivers to make it respond. If it fails, an exception is thrown and a bluescreen with memory dump occurs. I've noticed that they are much more common and frequent now (I also have 460's) with the newer drivers. There are a few things you an do to help alleviate them (and in one case, completely remove the issue):

1.) Roll back drivers to an earlier release (google around a bit, there is a known working driver for the 460s that doesn't seem to suffer from the issue)

285.62 seems to be somewhat popular for not causing issues

2.) Adjust the Video TDR timeout delay in the Windows registry as per this Microsoft documentation:
http://msdn.microsoft.com/en-us/windows/hardware/gg487368#E3B

3.) Sacrifice DirectX 11, current support, and a little security and roll back to Windows XP. This will completely absolve the issue, as it is directly a result of the periodic polling of the GPU hardware implemented in Windows Vista (and carried into Windows 7) There are hacked DirectX 10 packages available for Windows XP, so you won't be losing too much graphical quality.

EDIT:
A fourth option/possible fix has come to my attention. Completely wiping all nvidia drivers from the target system, and then performing a custom installation OMITTING THE HD AUDIO DRIVERS has been reported to stop the issue from occurring by several people. This seems VERY plausible to me; as if I switch my audio output device between my DAC and my GPU twice, my GPU TDRs and then my system becomes unresponsive.

I know nvidia is working on the issue because every beta driver release the symptoms, causes and frequency change drastically (I went from only crashing after several hours of gaming straight and then quick switching with Alt-Tab 3 times between the game and Chromium, to crashing when browsing the net, and then to seemingly no crashes at all)

Since then, I've adjusted the Video TDR timeout to 10 seconds for response and 15 seconds for Bluescreen and haven't had any issues since. You may have better luck with higher values.

Im already using the drivers without the HD audio drivers, since my fresh Windows install.

I've been using 285.62 since the day it was released, so I dont think its a very stable driver lol. Just today they released a new beta driver, using that now.

I decreased the OC by 40mhz, and I didnt have any issues for around 4h of gameplay, promising.
