All, We've all went to town hacking these 4850s. I got mine to run pretty fast, but suffered crashing while playing games. So then I reinstalled the stock BIOS (asus) and they still continue to crash. I've tried base 8.6 Cats, as well as a complete uninstall and cleaning, and fresh install of the Hotfix driver. Still crashing in games reliably, yet no info in event logs. Any ideas?
