7850 OC ratio

[Gav_881]

Hi just started playing with my 7850 and wondering about the ratio between the gpu clock and memory clock.

At the mo i have it set to 1050 and 1450 but i have seen people quoating 1250 and 6000 so i was wondering if theres any relationship and if theres a best practice way of OCing the gpu. also is there a do not exceed temp, running in a sff case so dont want to cook it.

Cheers

I think i have worked it out, the 1450 mem clock shows as 5800 in gpu tweek which is a factor of 4 so i'm guessing its like DDR speeds but a quad rather than double.

now to get some unofficial drivers and OC the pants off it

1150 and 5800 at 1.25v not the best OCing card in the world looking at other peoples posts but from a stock run of haven at 900ish it now hits 1450 with temps peaking 73 but the SFF case doesnt help there i dont think
