How do you overclock shaders with nivatuner?

You can overclock shaders separately

How do you get to that with nivatuner?

I run a 3d mark 06 test and got 10991

Whats that like?

640 core and 1000 mem - 70 degrees using atitool
 
make sure it's ticked too and restart rivatuner are you xp or vista ?
i think vista is
NVAPIUsageBehaviour to 1
NVAPIShaderClockControl to 1

I am using XP. Do i need to add that line as well? As I am using a 8800 GTS, everything else seems to work except the seperate shaders thing.

I put a light bulb next to it. Never ticked as well, that could be the problem, ill try that when i get home. Thanks

Thats exactly what i did! Do I save it or something after that?

Thanks, found out what is going wrong, the APPLY button is greyed out.

I guess that is my next question

Its got to be a drivers issue then as I have tried all your said. I understand how you clock it but it doesnt want to play nicely.

How to i check which nvidia drivers ive got installed?
 
Ok I installed the latest nvidia drivers and the shaders option came on straight away.

My current settings are:
640/1489/1000

What should I push the shaders up to?

My current temps are 61 idle and 86 maxed out.

Is there a temp gauge that i can use with this as at the moment i am using atitool?

Thanks
