hello guys,

i have gigabyte 4850 1Gb DDR3, 700/993... just want to know how to edit BIOS using RBE? i download my BIOS using GPU-Z and open using RBE... on the RBE, it shows that the state 3 which is maximum performance using only 1) 500/993 1.084v, 2)500/993 1.084, 3) 700/993 ---.

my question is :-

1) which value do i change for better overclock? my gc is stable on 740/1050 using stock cooler and stock Vgpu?
2) let say that on the clock info i change 700 to 800 and flash to my card, will the new clock is 800 or do i need to overclock again?
3) or just change the vgpu volt from 1.084v to 1.158v, flash to my card, and overclock using rivatuner?

i remember that 3dguru review this card can achieve 811 core clock, 1195 ram without modding... how came mine only can only up to 740/ 1050 stable?

cheers
