Firstly, here's my system specs: Intel D865GBFL Board P4HT 3.0GHz 512KB L2 Northwood Kingston ValueRAM 2x512MB Single Channel DDR400 ATI Radeon X850 Pro (R481) (500/500MHz) AGP 8X VIVO (I think) w/ Catalyst 5.8 Creative SB Audigy 2 ZS OEM Windows XP Pro SP2 I want to flash the BIOS to the XT or the XT PE to unlock the 4 pipes. I used ATITool and I get artifacts at 520/540 (X850 XT stock) with my stock fan/heatsink. I'm not sure how to remove the artifacts. I ran the fan at 100% but no luck. Do I have to buy a seperate cooling solutions to remove artifacts? Or is it that the card can't go any higher no matter what? I still want to try and do the softmod to the XT. But I can't figure out which BIOS is a PCI-E and which is an AGP, and which one's are R420, R480, or R481. Can someone suggest a BIOS I can use. And I also want to know how to revert to my original BIOS if I do a bad flash. The best score I got in 3DMark05 with stock was 4888. That seems way too low considering I had a softmodded Sapphire Radeon 9550 Pro (9600 Pro) that had ~1500.
