I had to get down with my OC again this time form 600 to 540MHz above that i have artifacts - this cards seems to be "dying" and no matter if you give 1.1-1.3 V on core :slapass: I understand that this is stock cooling and it isn't so good but for god's sake ONLY 40 MHz ??? :slapass: :slapass: As for now my X1800XL SUCKS :mad:
P.S. I should try tomorrow a better thermal paste on the core maybe this will help...
