Video Card problem!! Snow effect

[ffactoryxx]

So in some games I get a snow effect which is noticible in darker area's of games. What is this caused by???

I have a EVGA 6800nu which i unlocked the pipe and vertex

The clock settings are 325/700 at the moment which i think is stock.

Temps are 56c

Can somebody help me out?

Most likely it is a bad unlock. Artifacting can be a side effect after unlocking a card that should not have been unlocked. Unfortunately, there usually is not a way to "lock" the card back to the original settings. Its worth looking into though.

Your temp is fine, and stock speeds shouldn't cause any problems.

You could also try a driver update.

I thought you could lock the card back up with rivatuner

Ok, then that is the first step I would take.

My only experience with unlocking comes from a few years ago when modding Radeon 9500s into 9700s was popular. Back then unlocks were usually permanent, even if they went bad.

Whenever you have ANY problem like that, the FIRST thing you do to troubleshoot is remove any overclocking and return the device to stock speeds and timings.
