Which VBIOS is best for HD4870?

[Rodrigo Garcia]

I have a HD4870/512mb XFX, and I'm experiencing the famous white screen. The temps is low (63ºC) my 2 pents of 2gb RAM each is fine (ran memtest on boot, 6hours no errors), HD is fine, CPU is fine. Here's a SS from my GPU. Tried many CCC drivers and none solved my problem. When I put a low clock on it on AMD Overdrive, like 600/450, it plays fine but FPS is too low on many games, when I raise to 670/800, sometimes white screen comes, sometimes not, but on default clock (750/900) it freezes in less than 1min of play, regardless the temp on memory.

Can someone point me a good VBIOS for this graphic card, presuming that i can't change the board right now? Thanks.
