i;ve had this x800xtpe for almsot a year (late sept of 04) its not been thruohg too muhc, i put an amd heat sink on it but on all overclocking it was bencehd and brought back, and still ahsnt been pused to its limits. when i use hte ati overclokcing, it works great, never comes down form the 526 clock, when i use atitool "find max core" it climbs pretty high no errors 575 was the last clock i saw. HOWEVER. when i pick a clock and click SET CLOCK boom, artifacst all over the place. wtf mates. been doing this since 5.6 drivers. i can take it from 519 to 521 and it artifacts. wtf is up, why can it over clokc with the find max, but not the set clock function.
