How do you overclock shaders with nivatuner?

[Trusty]

Nice work!

 

[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?

You dont add them it's already there you may have to do the same to the nvapishaderclockcontrol above it in that pic for the 8800gts 320mb.

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

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.

which drivers are you using ? have you used rivatuner before ? you know how to clock the card right ? you know where to find the shader clock slider?
Reset everything on rivatuner or uninstall and reinstall start it up click on power user
then rivatuner/system and tick nvidiausagebehaviour and put in a 1 on the right then click ok now start rivatuner again and voila you should have the shader clocks in the overclocking section if not i suggest changing drivers.

 

[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?

This is an interesting article on shader clocking / rivatuner

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
