6850 Overclocking Problems

post #1 of 6
Thread Starter 
Okay so I bought my 6850 a few weeks ago. I've installed the latest drivers and it runs games no problem with expected performance.

However when it comes to overclocking I've run into problems. Using Sapphire TriXX I'm able to adjust the voltage, however whenever I do so I see artifacting everywhere, be it 2D or 3D. This is happening with stock clocks so I'm a bit confused as to why its occuring.

Help will be much appreciated guys.

It's doing this without overclocking. I can overclock it fine but if I play with the voltage I get artifacts.

How much voltage did you increase? I can increase vol to 1.3V all the way but it will freeze games, without artifacts.
You should be able to increase vol to 1.2v without problem.
And hey, 1ghz is a pretty high overclock already, back down a bit. At 1Ghz I doubt you can pass 15min of Furmark.

Even the slightest voltage change will cause the problem. Like anything over 1.17 and I will start getting little squares everywhere.
