Help With Overclocking

[Aquai]

Hey all,

Been looking around the forums and today have attempted to oc my card. The main game i play is CoD 4 and was running at about 35-45fps which wasn't bad. . . but i was experienceing problems with WoW so decided to change my driver settings so looked around and decided to go for 169.04 with oc'ing.

So i downloaded it and installed and downloaded riva tuner and changed the settings to;

Core clock: 640

Shader clock: 1280

Memory clock: 475

I then ran CoD and got a fps of 10 max, on lowest settings... Any suggestions or ideas as to what i could be doing wrong?

Additionally you can try some GPU power hungry games (Eg:FEAR /SCDA/COD2)

# 3DMark06 tests are very important!!! please do it.
