on my 7970 I have 298H/s with 1100/1575, and it works without crash
but i can't improve my Sapphire 280x Tri-X OC to this results, I have only 286H/s in stable. What clocks are you used?
p.s. timings are 1250MHz

Strange

I tried to mod bios, but i did not achieve any increase in performance. Maybe you could share your bios domp of 280x? atm i get 245-260h/s

For save you card alive you must edit your stock bios file. Bios from another model of card can make a problem, or even brick card. There is a automatic patch to Tahiti.rom files, but it don't help me, because card pump to +500H/s and almost all shares was rejected)) May be it help you))

I wanted to open your bios dump in Hex Editor, to check memory timings and compare with my moded bios. thank you.
