Been doing this in secret. I flashed my Palit gtx280 to EVGA bios rev.5 over a week ago. It's right now running games at full oc, and even folding a bit. The last Palit bios I could find was rev.3. These are all reference bioses for reference cards. Only need to update, is for fixes. Palit gave up at rev 3. This may still go badly for me, it has for 2 consecutive gtx280s from Palit, but it seems more stable than I've ever seen it, and the last time I used it, I couldn't boot windows. Cross fingers!
