RivaTuner 2.24 Not Running on x64

I was trying last night to get RivaTuner to run on my Ultimate x64 machine, but I'm stuck on one particular issue... Hopefully somebody else would be able to shed some light on this.

It seemed to install without a problem, but when I try to run it I get an error with loading the 'rivatuner64.dll' driver. Looking at the file name it seems to be picking up that I have a 64-bit OS, and is trying to load the appropriate driver, but I suspect that it's not loading because this driver is not digitally signed...

I found a post on the BitBenderTech Forums (link) where the check for whether a driver is signed or not can be disabled; but I'm wondering if this will cause problems with other installs? To be safe, should I maybe disable it, get RivaTuner running and then enable it again?

I think a good alternative maybe to try either evga precision or the nvidia overclocking tools ntunes.

I did not try Riva Tuner on x64 and I think I will not... :)

I've been using eVGA Precision 1.9.1, I like it because of the overlay in full screen apps where I can see both GPU temps and FPS, but the overclocking side doesn't work too well... I've never been a big fan of nTune, but for some odd reason it doesn't let me do much at all on Win7.

Since I flashed the BIOS on both 8800GTS's to the same version it's better, but Precision doesn't always apply the same overclock settings to both cards. I end up with one card running 600MHz GPU as I set it and the second dropping to a random number like 586MHz.

My next stop (if RivaTuner doesn't work) is ATITool; I've heard it also works on NVidia cards, but I'm not sure yet what it will do with an SLI setup...

Edit: On second thoughts, I'll just skip the ATITool idea, it doesn't work with SLI, only single NVidia cards or Cross-Fired ATIs.

Have been using RivaTuner v2.24 on Win 7 x64 Ultimate for quite a while now...works flawlessly. I also had some trouble initially. Here's what I did to get it working...

Just get a copy from RivaTuner (if you got it from somewhere else). The file is called 'RivaTuner224c-[Guru3D.com].exe' - it's a zip containing TWO files 'RivaTuner224MSIMOA2009Edition.exe' and 'RivaTuner224MSIMOA2009EditionDrv.rtu'. From what I understand it's the .rtu file that makes it work on x64. Anyway, just ensure they are in the same folder and install - then select 'Yes' when prompted to install available updates. That's it...should work without any problems.

You realize that Precision is nothing more than RivaTuner with a few less options and a fancy GUI (same goes for the one from MSI), as it is written by the same person that wrote RT.

Also best place for help with RT,

when installing rivatuner it will ask if you if you wish to update, click yes. it is loading the rtu file at that point enabling it to run on x64 system

Yup, I kinda figured that when I got an error from the installer while Precision was still running.

Here's where I went wrong though, I didn't do the update... I just extracted the exe and ran it. Now that I know what the rtu file is for, I should get it working tonight then.

Thanks you guys, really appreciate the help.

Ok good to know thanks. I had found them to work very much alike but did not know they had the same origin.

I use Ntunes now when I need to overclock...but even at stock speed my gtx 260 black edition (216cores) can handle almost anything...so I usually end up just raising the fan speed so ntunes is enough for me.
