Artifacts at not so high OC even with watercooling

post #1 of 20
Thread Starter 
I got 2 HD6950 that are watercooled and at 900MHz it works fine and i think its around 45c at full load and at 920MHz its probably only 5c more but im getting artifacts??
Do i need to somehow increase Vcore on the cards?

I find artifacts to be caused mostly by memory and shader errors...have you tried reseating the blocks yet? I'd be curious to see if maybe a thermal pad wasn't properly applied to a memory chip, and it's overheating and causing issues. It could also very well be a defective card, but I would check the block first. Maybe you could also try running them one at a time, and seeing if the problem persists.

Regardless, there is a water block over them, which I assume to be end-user-installed. An error might have occurred while installing it.

What GPU voltage are you using? The stock 1.1v? If so that is almost certainly the problem.

No the memory is from stock not cooled. Even so i have mounted small copper heatsinks on them and the waterblock is only on the GPU

how are vrm temps ?, check thermal pads under backplate, they could be missing or badly done which result on bad memory cooling
post #8 of 20

Again its not the memory. They are not even overclocked and there is no sign of graphical glitches when the core is at 900MHz or lower so this IS a GPU issue and most likely the voltages like Blameless said. I just need to find a guide to increase the voltage

This is the problem then. Most 6950s aren't going to be stable past 900MHz or at stock voltage, no matter how cold they are, unless we are talking about subambient cooling.

You'd need some 3rd party OCing utility to increase voltage. I use MSI Afterburner.
