Im having trouble getting my new X1800XT 512mb to work properly. Whenever i attempt to run the 3dmark05 bench test it fails on the second scene (everytime!). When i say 'fails', basically it appears to get graphical error lines up and down the screen, if i dont exit the test it will eventually crash altogether.
Now my first thoughts were it was a driver problem, i did have version 5.13 + CCC, although after installing the latest drivers 6.1 from the ATi website im still having the same problem. This also occurs while playing all latest games like Battlefield 2 and COD2, titles that i used to play ok on low settings with a 9800XT.
My Spec Is:
AMD 64 X2 3800+ (bios updated to 1009)
Asus A8N-SLi Premium nforce4
ATi Sapphire X1800XT 512mb
250gb Western Digital HDD SATA 7200rpm
500w Antec NEO Power Supply
17" TFT LCD Monitor
First, is your CPU overclocked? I doubt if this is to blame, but it might be inspected. I had problems with Aquamark due to my cpu running 64Mhz higher.
Also, get ATITool (latest version) and check your temps on the card. Heat most often cause graphical errors and a system hanging. The X1800XT uses case air to expel outwards, maybe the temps inside are on the uppish side. But on the other hand, the Radeons can go quite high. I remember my X800XT going to 95C and still no problems.
Lastly, I see I you have a 500W PSU - more than enough, but make sure that it is indeed supplying enough power on the 12V rails, especially the Amps. The X1900XTX requires 30A. Dunno about the X1800's.
