Hi guys, I've just recently got a pair of sapphire 5850 xtreme in cf and I've seen peoPle pushing to 840/1200 at stock voltage. Doesnt seem to be working for me as it sometimes crashes on games like BFBC2 and furmark. I tried Sapphire Trixx to bump it 1.1volts but no avail. Ccc 11.8 and load temps at 80'C seems pretty high.
Used to have a xfx 5850 xxx and it displays on my 42" Tv no problems. But on my cf sapphires, it goes black screen on my tv. Any ideas?
