Is it possible to flash a factory overclocked bios to the same factory's card but not the overclocked version. Will it help with overclocking even if you cant get the card stable to the factory overclock. I know most factory's test their cards and keep the better ones for their overclocked models (eventually the same chip but was manufactured better) I am running a Powercolor 7770 and i can max out the mem clock on the current bios NP no voltage change or anything the core clock though i cant get to the factory overclocked speed. So in this situation Will the overclocked bios change the voltage for me to a factory tested range hopefully letting me get the core higher safely or should i just do it the old fasioned way and play with voltage and just keep my mem clock the same? The stock clocks on this card is core 1000 mem 1125 My current clock core 1010 mem 1300 Factory clock settings Core 1150 Mem 1250 I have seen other 7770s (online of course so grain of salt) with voltage changes and some without (depends on lucky cards etc i suppose) i have seen easily in the range of core 1100 mem 1500 both on the low end of the scale. So will the bios change be detrimental or beneficial to this? ESP since the mem clock is bios locked to 1300 on this card (possibly on the overclocked bios too) SO really i am only interested in the overclocked bios if it possibly ups the voltage (SAFELY) and lets my clock my memory higher and possibly core too i can only get 10 on the core but the memory seams to be no problem every time i pushed it and benchmarked it just kept going. I am already planning on upgrading soon I'm running 2 right now and want to upgrade back to a single. At least with crossfire yearly GPU upgrades are not that bad as you get more bang for the buck (most of the time) just waiting for the right price.
