Unable to overclock in Nvidia Control Panel

I'm using a brand new Gateway 6860 and I just installed the 175.70 drivers off Guru3d and the install went fine.

In Advanced mode, I only have access to 3D Settings, Display and Video/TV, no GPU access. I tried RivaTuner and it gave me some bogus settings that were way below the 8800GTS's range (performance3d started at 380 clock speed and I couldn't move shader speed past 1150.) It's pretty late right now so I'll try using different drivers tomorrow, but does anyone else have an idea what's going wrong?

 

1) Drivers arent OC'able on Ntune

2) Did you let RivaTuner detect your GPU stock clocks?

 

Use Rivatuner.

 

What's the difference between this and all the other Nvidia drivers I've used that have enabled it? Do those come with a different utility from Ntune?

Yep. It's bugging me now so I tried it with Powerstrip and got the same thing. 383 clock/300 memory. I can't even increase the speeds past 509/400. And both Riva and Powerstrip have recognized the card properly.

 

Ugh this is wierd. After messing around with different versions from Guru3d and laptopvideo2go, I finally got the clock speed back to normal, but I still can't overclock. The diagnostic in Riva says it's running at 540/1350/864 which is great, but when I try to touch the overclock settings, it still only gives me max settings which are way below the default numbers. At this point I'm just going to leave it because those numbers seem good.

 

If your using rivatuner's build in clock speed detector, know that they arent very reliable, use GPU-z's build. And also your graphics card uses different clock speeds for different applications based on graphic intensity. So lets say you OC to 650/950, and you try to detect your clock speed in windows, its gonna most likely show you 325/700 or something, open up a game and start playing and you'll see detected 650/950 clocks.

 

Even so, why is it that overclocking is so limited in RivaTuner and Powerstrip? I searched and saw people were having this underclocking issue with 8800s and Riva back in January but I didn't find a solution.

 

I use ATITool for my 8600m GT GDDR3. It's not easy to install, but it lets you create your own clock range.

 

Alright, well I guess it's just an issue with Riva, not with any of the drivers at guru3d. The default overclock settings are still wierd, but I just went past their settings by going into Power Users -> Riva Tuner\Overclocking\Global and changing MaxClockLimit to 1000 (or anything high really.)

Hope this helps if anyone else has a problem with this.
