ATI Radeon 9800 Pro: Trouble... Please help... =(

[CHiM721]

I had just built a new comp... everything rnus great...

Corsair DDR400 PC3200 512MBs RAM
ASUS P4S800
P4 3.2Ghz w/HyperThreading
ATI Radeon 9800 Pro 128MBs
80 Gig Maxtor Harddrive 7200RPM

The problem is: When I run the demo of Unreal Tournament 2004, I can play for a little bit (10-15 minutes) then the screen goes black and the monitor power button starts flashing. I try CTRL+ALT+DELETE and I still get no response. I have to reboot and everything is fine again. In Windows and everything else it runs extremely smooth with no problems. I have all of the right drivers for my hardware. I have no idea what's going on here. I have the graphics aperature size set to 128MBs. Please someone help. Thanks... Matt

*slap* calm down woman

me thinks ur cpu might be overheating. mine did the same till i discovered that my hsf was making proper contact with the cpu and the temp was shooting to 70c + causing thermal throttling, which freaks out UT2K4 for some reason.

also try re-installing the game and/or lowering some of the options esp. any filtering.

whats cats/omegas u using?

Well that definately wasnt my problem, my CPU runs around 30-35c under load. So go to sleep! lol

Are there any known ATi issues with the UT2004 demo? I know NVIDIA has a performance problem thats going to be fixed in the next driver revision.

Try lowering your aperature size to 64meg in your bios. I believe you should only set it to half of your actual video memory.

I am pretty sure Aperture size should be set to half of your system memory. They wouldn't off such high values for it if it was half of Video card memory as 256mb has only been out a relatively short while compared to whats avail in ios setting for Ap size.

I'm running a 450Watt power supply, Windows XP, and the Catalyst 4.2 drivers. I tried using the 3.1s as well, but there was no difference. Also... what is VPU recovery. I don't know where that option is. Thanks...

This is sort of a widespread issue. You can find a lot more people with problems like this over at rage3d.com. I had this for a few days, and now it seems to have stopped. I was even getting random lock ups in internet explorer. When I'd restart, Windows would tell me that a device driver for my 9800 Pro had failed while attemping to draw something...

At least now I know what everyone talks about when they say "ATI drivers suck."
