Ok, first let me start by saying I bought the 5850 about 2.5 months ago for the configuration as follows
i5-750
P7P55D-E Pro
4GB Geil 1333 DDR3 7-7-7-24
intel x25 80 GB Gen2
Cooler Master HAF case
Windows 7 Professional OEM
ASUS VW246H
the graphics driver and the monitor driver are both up to date. when i first got this card i overclocked it to 850cclk and 1200memclk using CCC, and it worked fine and ran stable in any game graphically up to fallout 3. just yesterday i was playing Civilization 4 and massive artifacts started appearing, also the game suddenly froze and went black for about 15 seconds. after this the game resumed, with the artifacts still there. now one thing i must note is my girlfriend did turn up the room temperature to 90 degrees F. whenever i looked at catalyst it always showed the temp at about 56C on the card same thing in speedfan. now i turned the clk's back to stock and was playing crysis at full settings 1440x900 and it ran just fine... is it possible that my card just cannot overclock that high with CCC? might i have to use the BIOS to perform such an overclock? is the card faulty at such settings? or is it another component or driver of mine?
if you need anymore information just ask, i thank you kindly in return.
