I just orderd a Sapphire 4890 vapor-x. It will hopefully arrive tomorrow or tuesday.
Ive been reading some today and ive read somwhere at xs that the vapor-x doesnt use the volterra chip so it cant increase voltages through software. Is that right? It never got confirmed so im hoping its not true.. What voltage is stock for the 4890 cards? The vapor-x is running 870mhz so its not a heavily overclocked card.
I read that instead of increasing voltage through software it is still possible to increase voltage through a bios flash? Is that right? If, how high can i set through bios mod? How does the vapor-x usually do when it comes to overcklocking since it use other pwm than most of the 4890?
I found a bios to the card now. But when i load it up into RBE the highest voltage that i can set is 1.313. How do i increase it ?
