Graphics Freezing... HELP!

[kensai13]

I just built a new system and am having a problem. Hope someone can help. This is the build...

Gigabyte GA-P35-DS3P Rev 2.0
Intel Core 2 Duo E6750
4x Crucial Ballistix 1gb BL12864AA804
BFG 8800GT OC2 512MB
Silverstone Strider ST60F 600W PSU

+3.3v / +5v / +12v1 / +12v2 / +12v3 / +12v4
33A / 24A / 18A / 18A / 18A / 18A

Drivers are all updated.


Everything seems to run fine except after playing Crysis for around 20-30 minutes the screen freezes and gets all pixelated and red. I get the same problem when I run the Ntune stability test.

The videocard fan is running fine. The case isn't hot inside. I'm not getting any heat alarms. Not sure what to do.



,Thanks in advance for the advice.

Have you tried underclocking your video card to the stock speeds and trying to run the same tests again?

I've heard of cases where the factory overclock is simply too aggressive causing the card to be unstable.

Hmm... I'll try that tommorow. Do you know what the stock speed is? Any other ideas to try?

The stock speeds are GPU: 600 MHz/Memory: 900 MHz.
You can set the clock speeds using nVidia's nTune utility.

Another good tool for stability testing is ATITool.

Sounds like your video card is overheating, use nTune to check the temperatures.

^ @ MetaDFF: I don't think that works with nVidia cards.

You mean ATITool doesn't work with nVidia cards?

Used Rivatuner to crank up the fan speed and now it's runnin like a champ. Guess the stock cooling is JUST BARELY enough for these factory OCd cards. Seems solid now, if a tad bit loud. Thanks for all the help.

Welp, I've actually just checked that out and apparently it does indeed. My bad.
