Overclocking my HIS HD6950?

post #1 of 4
Thread Starter 
Hi, the fan in my 6950 broke so I brought a thermalright shaman as a replacement, now since I spent a butt tone if cash on this cooler ($90, 3 times my CPU cooler) I want to overclock my card, now I know I can unlock the shader or flash the bios but for just a normal overclock what have you been able to achieve? What temps, what fan and what memory, voltage and What speed your running at. Now hears a hypothetical, let's say I oc the memory to 1375 (I think that's max) and the core to 920, how much of a performance increase from stock (800) would I get?, and do you think I could hit 1ghz on it without blowing it up?

Thanks

Ahhh all cards are different homie. If i were you id just start from scratch. Use Msi afterburner Or Amd overdrive. I prefer Msi afterburner because It has voltage controll (if your videocard supports it) And yea Check it out. Just dont burn your card up

well yeah, I guess you can overclock it some.

if it was on stock 800, and you increase it to 900+, it will perform better then 6970, as they are more or less the same cards (if you have reference designed one). Start with core clocking, and when you reach what you feel is ur limit; Clock up memory

most performance boost is gained from core clocking, Memory is but a small part of it.

you will fast earn 5-25% performance boost on your clock between stock settings on 800mhz to 1 ghz.

personaly I just ordered 6970 LCS series, with watercooling. stock clock on that is 950 mhz core.
and 6950 is the most performance pr watt and money card at the market atm

But please, I dont want to see you returning to overclock with pictures of the card burned up :<

you're gona make me cry XD
