How do you overclock shaders with nivatuner?

[bloodline76]

I have overclocked my core and mem but dont know how to overclock the shaders?

I am using nivatuner 2.06

Thanks

You can't do it separately in rivatuner but the shaders overclock with the core.

If you use gpuz it will show you your current core, shader and memory clocks.

Someone said that there is an option to seperate them. So that the core and shaders werent linked. Is that not not true then?

 

[bloodline76]

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

If your on xp you must go to power user system rivatuner and make nvidiausagebehaviour set to 1 that unlocks the shader slider

I cant see that settings in power user?

Can you show me a picture?

 

[bloodline76]

Go to the power user tab, in there should be loads of drop down menu's, go to system and within system should be nvidiausagebehaviour. Click to the right and set at 1. Hope that helps!

When i change it to 1 it doesnt do anything?

 

[bloodline76]

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

 

[bloodline76]

Well i have tried adding those option and putting ticks next to them but it still does not work. Any other ideas?

 

[bloodline76]

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

 

[bloodline76]

press ok

Ive been doing that and it doesnt do anything. I am going to uninstall and reinstall it. Running out of ideas

 

[bloodline76]

Uninstalled and reinstalled and this still isnt letting me change it.

Thats exactly what i have tried.

I cant see what else I could try. I have done exactly what you have said.

 

[bloodline76]

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?

 

[bloodline76]

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
