Hi. I got really weird problem with flashing my card. I tried to flash it with ASUS TOP bios which have stock clocks 815/925 - My card performs with no problem at those speed. So when i flashed it under DOS (pendrive) it told me to restart my PC - After restart no post... black screen. Then i took my ATI MACH64 and put in PCI slot. Reflashed again with ASUS TOP bios - no luck again. I took my original SAPPHIRE bios and everything works as it should. Why i cant flash this bios properly ? PS: I used : "atiflash -p -f 0 asus.rom" command... HELP PLZ.
