Great Post hammermdGreat post hammermd, with the links and explanation, though i flashed in the past it had been a while, googled found this post all in all took maybe 15 minutes. I did the auto overclock it recomended 575by754, flashed straight to 600by700 did auto overclock again it recomends 625 by 754.
Just running ATI Tool arifact tester, i know its not infallable having used it befoore being told no artifacts found but getting lock ups in games. But its still a good first test and am watching temps with precision fan control. peaked at 74 with dells bios controlling the fans. So far no artifacts.
Ran 3dmark05 all default and set at quality with Nvidia 84.63 Drivers, abit spookely, scored exactly 9400 no artifacts.
Ran it again set @ High performance scored 9308 :P
Then again i have run 3dmark in the past a few times over and got that kind of difference without changing any settings.
Will update with further tests.
I would guess that this card might be like my PCIe 7800gtx which has three clocks the core clock and others you could adjust the core clock up say 30mhz without it changing the other clocks and also showing no performance increase, so you set core at 500mhz it was ok but at 501 the other lcoks jumped up about 40mhz then artifacts, just a thought to ponder.
This whole flash thing vs overclock tab is probably a good thing, i remeber a few years back when i was new to it i told a friend about coolbits, when i saw him again he was abit sheepish saying his card was broken he later admitted because the tab offered somthing like 1ghz he wapped it straight up :P he had somthing like ti4200.
Side note, does anybody know if it is possible to OC with clockgen, i guess you might have disable speed step thingy in bios ?
