Problem with x1950 pro

[sniffy]

Hey lads

This is a strange problem. I'm only having issues with the crysis demo. Basically after 15/20 minutes, the graphics corrupt. Green squares constructed with nasty pixels appear all over the screen. The PC doesn't crash; the graphics corruption carries over to the desktop. The only way to revert the screen back to normal is to reset the PC. No other game does this, only crysis.

I've tried different driver versions for the graphics. I haven't updated BIOS as I don't have a floppy-drive around so if the flash corrupts, I'm pretty screwed. Is this likely to fix the issue or do you guys think it's something else? I'm unsure; I've searched google and found numerous people having issues with the AGP version of this card (driver related) but they have serious issues effecting ALL games. Maybe the card is overheating? I don't know, hence the thread.

What do you guys think? Thanks for any help

Spec:

AMD64 at 2.3GHz
2GB geil PC3200
Sapphire X1950 pro 512mb AGP (Running at 4x due to incompatibility issues, performance is still sweet though)
Windows XP SP 2
7.10 catalyst

could be temperature. i know playing crysis on my x1950pro the fan speeds up and pretty much stays that way although i dont get any problems. If you search for any #graphics card# and #problems# you will find loads of people with them. try checking the temperatures

I might give the fan a good clean then.

I have searched briefly on OcUK but I can't find someone with my problem. Similar problems yes but not my actual problem.

It's most likely the memory chips don't have heatsinks as per with a lot of these 1950 pro's.

Try running AtiTool or everest in the background and minimise the game to see what the temp is for the core.

I had serious issues with mine overheating in AoE3, was getting to over 85 degrees. Swapped the stock cooler for the Accelero S1 and it sorted the problems, and have managed a small overclock on it. Jus run a 3DMark 06 test and got 5463.

OK I'll give that a try. Thanks

What is a good temperature for a graphics card under load?

 

[schumi84]

Difficult to say really, i like to see it below 70 really, with the new cooler it is at about 50.

Thanks again It seems mine is running way over that; 95+ under full load Surprised the thing hasn't died yet.

Overheating must be the problem. I'll give it a clean and if it doesn't improve, I'll order up a sweet cooler.

Edit

OK I took her out and gave her a clean. The temperature has improved but not by much During the crysis GPU benchmark, I've caught the temp at 85c. I'm going to game on in after I've had to some food to see if it continues.

By the way, CoD4 started crashing the system (graphics card loses synch with the monitor, need to reset) so it isn't just crysis :/ Nice to know I've identified the likely cause of the problem though.

Thanks for all your help!
