Upgraded to an X800XT AIW (agp) just before New Years, ran perfect for a month until I got tired of the fan. Luckily the GPU location was close enough to where it was on my old 9800Pro, so my waterblock lined right up. Ran great for a month watercooled. Decided to open up ATITool one night (first time OC'ing this card), found max memory just fine (can't remember how high). But while trying to find the max core speed, it kept going until 603MHz, then tossed up an error message saying that I had to restart to get the stock settings back again. Temps were fine the whole time, according to the diode snuggled up next to the core. Since then (maybe not directly after), I've noticed errors and slight artifacting even while at the desktop, horizontal lines and horizontal chunks/bars mostly. Running the ATITool artifact scanner at stock speeds didn't go very well, it would find small errors right away and then start artifacting.
Tonight I took the waterblock off to check contact, and everything looked good. Cleaned the block and core with the trusty 99% isopropanol, spread a thin layer of AS5 on the core, and tightened the block down. Uninstalled what was probably 6.12 Cat's, and installed the new 7.2's. Still showing horizontal bars and causing errors in ATITool while scanning at stock speeds.
Anything else I should be trying? I seem to be having bad luck with video cards these days (9800Pro artifacting in HL2 became so bad it was unplayable). Anybody ever damage a card while using ATITool?
