XFX 6870 Overclock

post #1 of 3
Thread Starter 
Well so I got my gpu block and got my video card under water. Wanted to see the max I could get it to oc. I was able to do 1000 core and 1200 ram @ 1.2.v anything over 1200 on the ram even with 1.3v just crashes.

Well anyways I'd figured I test stability. Fire up OCCT gpu test everything on default error checking on. So it goes no errors but its only average like 380fps.

Now my previous oc of 950 core and 1150 ram @ stock voltage and it average about 430 fps.headscratch.gif

Now I dunno if fps in OCCT really mean anything but I would figure higher OC would mean higher fps.I haven't tested any games yet. I was wondering if anyone has had similar experience or if fps in OCCT really mean anything?

And its not temps core usually doesnt even break 45C after hours of gaming. Block is cool to touch as is the board.

There is no point to go higher as you have tested with higher memory clock gives you diminishing result. That's where you know the memory ECC kicks in.

I would stay at the bolded above clocks.

Edit: No point to stress the Core/memory with higher clocks and voltage without the benefit of performance but added heat and power draw.

Yeah okay that's what I thought. Well thank you. I will have to look up some info on this memory ECC thing.
