6950 Overclock Settings - What are you running?

post #1 of 52
Thread Starter 
I see TONNES of 6950 overclocking threads on here but i can't find anything with a list of everyones clocks and voltages for this card.

I am curious as i'm running 900 / 1400 @ 1.16v but i have seen others claiming they have 950 / 1450 on stock voltage!

I know it varies card to card but if you could post your clocks / voltages in this thread it would be interesting to compare them to see if the same brand have different results?

I would ideally like 950 / 1450 but I yet to finsd a stable overclock that will let me achieve this target drunken.gif

So to start:

My System: PowerColor HD6950 900 / 1400 @ 1.16v UNLOCKED SHADERS

Fairly certain it was meant to be 1.16v tongue.gif

I can get my card to 1GHz/1400 on 1.25v; folding, furmark, ati tool and gaming stable.
However I usually just leave it stock unless I'm gaming or benching, in which case I set it to 980/1350 @ 1.2v.

Eh just stock 6970 clocks with the flashed BIOS.
Haven't messed with voltage excessively since the card already breaks 90C in Furmark as it is..

I'm at 1.165v, 950/1425 atm, I could Increase the memory by a lot more without getting artifacts but I'm too scared to damage something

Didn't unlock shaders yet because I want to make sure it's a stable card first to not have problems with RMA if something is broken


I need at least 1.19v to break 960 without artifacts so i decided to not oc further than 950

edit:
what is the best real stability test besides GPU tool?
Burn in test with extreme burn in preset?

I have just ran 925 / 1450 @ 1.2v 100% stable in Just Cause 2 and DIRT 3 benchmarks

Max temp 65 degrees smile.gif

Tried 950 / 1450 @ 1.2v and it crashed in Heaven. Maybe i should stop at 925 / 1450

How on earth can you get a stable 1ghz / 1400 on 1.25v!! That#s crazy

I don't run my overclocks 24/7 i only apply them when gaming or benching too.

WHAT THE HELL! They are crazy overclocks....strange though because i run Just Cause 2, maxed out and get 68fps average framerate which is 25pfs more than you and your only running x8 anisotropic filtering and medium shadow details
