Hey guys, just installed the new 7.8 catalyst today. OCing now works very stable for my card. CCC seems much better regading stability. Went up to 850/1700 (800/1400 stock) with the following results 3DMark2006 - 3809 3DMark2005 - 8026 Still not great, but I won't complain. Got that figures without bothering to turn off any running apps or optimizing anything and with a system that is now running for more than 4 years without reinstall. Anyway - my card is now running 63° on idle and 75° on load. Before it was 58 and 72, so no big increase. (Interesting that idle increased, 2D clocks are unchanged....) But what I am really curious about: What are the recommended/tolerance temps for the 2600 XT GDDR3?
