dear all,
i'm trying to get my sapphire 5850 toxic OC'ed.
i have seen OC's of 950/1250 and even 1000+ (on watercooling), so my goal of 900/1200 should be easy.
stock speeds are 765/1125, and CCC is capped at 775.
i have tried MSI afterburner, but as soon as i go over 825mhz i get artifacts while running 3dmark (voltage too low?).
unfortunately the voltage is locked in MSI afterburner (sapphire bios overrules?), so i would need to flash the bios to get any higher.
could someone help me with a good bios?
maybe the one from volkswagen? After Bios Flash 5850 Stuck in 2D Clocks
also in the download section i find the ATIFlash 3.79, would this be ok?
i have also seen someone with the stock 5870 bios, is this a good option?
please tell me which bios to use and how to do it properly.
another option would be to voltmod, but is this necessary and doable on the 5850?
in short my goals:
quiet while browsing (low fan)
900/1200 in games
edit: just thought of posting the rest of my system also.
e6750, 8x475mhz
ocz reaper 4gb 1066 memory, 2x475mhz.
gigabyte p35c dsr3 rev 1.x
if you need more info, please let me know.
