I resently got my brand new Sapphire x800 GTO^2 and over clocked it to 542.24 core and 621 mem and then flashed the BIOS to unlock the extra 4 piplines. What I would like to know first of all is how do I ATIT tool to over clock my card automatickly at system start up? Second, is my card modable so that it balieves it's a x850 XT PE? Also, after I preformed the mod my system became rather unstable. Every thing ran slower and I could lonch NO games OR scan for artafacts, not evin Half Life 1. After unistalling its "updated" drivers that windows atomaticly installed and catalisk and reinstald catalisk every thing worked pefictly. Smooth as butter. The intresting thing is that when i serched for my max core to see if it was still good to go at the high clock, the core climed clear up to 553.53, generating no errors. It kept climbing up to about 560 MHz with befour my system randomly restarted; I balieve this instability is do to 300 watt power saply pushing 4 IDE drives (2 hard drives and 2 dvd berners). The card is compleatly stock, havnt done anything to it other then flasht he bios. Is it safe to continue pushing the card to thies newly achivable core clocks with my system? Also the memory has clocked up to 660 MHz with no artifacts jenerated but then my system spontaniusly restarted at 663 MHz.
