How far could I overclock my 6870 without touching voltage?

post #1 of 10
Thread Starter 
Right now I am at 970/1120 and I haven't touched the voltage. I just refuse to touch it.

Anyone been able to get to 1000 core and 1150+ memory without adjusting voltage?

GPU's vary between one another... I suggest just continually upping the clock speed and testing it.

uhh, i think the 6970 has a 1350 stock mem clock....O_o

either way, i have a reference 6950, unlocked to 6970 shaders & clocked to 1003/1380 core/mem.....stock voltage everywhere on the GPU...

so i think you should be ok to get some nice numbers, as long as you cool it well!!

Except he's asking about a 6870.

I always mis-read things while half asleep, well then you should be able to get about 925 core and 1200 mem i would think

Are you using MSI Afterburner?

By leaving the voltage locked, it's set to a certain voltage that it runs at. IMO, I'd just slide it up and find instability and find the sweet point

You've already OC'ed without touching the voltage and you refuse to adjust it.

So you were OC'ing and then decided to STOP OC'ing just to come on here to ask what speeds you'll be able to reach using the methods you've already been doing without trying anything different?

There's no way we can say, just keep doing what you've already been doing til its not stable. I don't see what you were expecting people to say.

My Sapphire 6970s refuse to stabilize on stock volts on anything over 910 Core and anything over 1400 Memory. . . This makes me so sad because its stock clocks are 880/1350 . . As previously stated, each card performs and stabilizes differently due to minuet changes in the Silicon and internal component quality.

MSI's Kombustor works well as said just work it up, Apply in say like 5-10 mhz intervals and run a quick stability test. I don't think you can go much above 950 on stock but worth a shot.
