How to Unlock Overclocking in Vista 64 Bit?

[JosephBAdams]

Guys, I have an nVidia GeForce 7800 GTX that I would like to overclock. I'm running Windows Vista 64-bit, and I have found no results searching the Internet for instructions on how to overclock in Vista 64-bit. It certainly doesn't work the way that it did in XP, where I added a value to the registry and overclocking was immediately possible.

I'd prefer something straight-up instead of having to use some sort of registry-hacking utility.

Any suggestions?

Your options are ntune from nvidia, Rivatuner (most popular here), or EXPERTool from gainward.com (what i use personally).

That being said, none of these are totally 'straight up'. nTune just kinda sucks, rivatuner is more complicated that it needs to be, and EXPERTool is from Gainward - athough it works fine with my XFX card.

The only problem I've run into with EXPERTool is that is doesn't work when I've tried it with dual monitors.

Nitromullet, how well does your Gainward utility work?

Very easily... You just install it, set the clocks, and set it to autostart with windows. It doesn't have any tools to help you determine your max clocks, so it's trial and error. I've used it in conjunction with ATItool to test for artifacts.

I see that you have a P35 motherboard also, I would suggest staying away from nTune. I tried nTune recently, and it tried to overclock my cpu. This resulted in me having to reset my bios and redo all of clock settings. I don't see why nvidia doesn't disable that for non-nforce chipsets.

Rivatuner works extremely well. Very powerful if you need it to be.

Rivatuner is usually the application of choice in Vista 64- the latest version comes with signed drivers now aswell.

Thanks. So far I'm using EXPERTool and somewhat satisfied with the results.
