My Sapphire X1900XTX arrived yesterday (woohoo!). I had RMA'd an MSI X1900XTX and now glad I did... I haven't re-installed ATITool yet, as I wanted to test overclocking in CCC. I ran the "Automated" utility in CCC, and the core got up to the max of 700 (698), with a temp reaching 81c as the highest. Idles in the low 40's. Good results for the core. But... interestingly, the memory did not budge frm the requested stock. Question... does CCC attempt to overclock the memory as well as the core? Also noticed the fan never kicked in, even at 81c - what's up with that?
