I just purchased an ATI X850 XT (AGP), and when I got home I set about testing and benchmarking. The first thing I did after installing the newest catalyst 5.13 drivers was install ATITool 0.25 Beta 11. I've had great success using ATITool in the past on my previous card, a 9800 Pro. Anyway, a strange occurance took place when I ran the first 'find max core' test. It went all the way up to 580 Mhz without detecting ANY artifacts, and I started to see some weird yellow fuzzy-like border appear around the cube, so I aborted the test. I checked the log afterwards and confirmed there were no reported artifacts. Also, I had temperature monitor reporting every 3 seconds and it never got above 63C. What's up with that? I've never seen any artifacts in ATITool other than white pixels, and I've never seen ATITool NOT see the artifacts when they're there. Quick system specs- Intel P4 2.4C @ 3.0Ghz on DFI Lanparty PRO875B. 1 Gig of Corsair 3200 DDR mem. Win XP pro Thanks in advance for the help!
