Why not you remove the HSF and re-apply the thermal compound with better ones like TX2, etc? I did mine before even plugging into the PC. Secondly, try to overclock with only increasing the core/shader first. In my case, the memory doesn't like to go beyond 1160 stable (for whatever reason).

Download GPU-Z and backup from it?

As far as I know, GPU-Z should extract things correctly for nVidia cards. I have not tried on an ATI so no ideas. Maybe a better explanation and example of what might be missing should be provided

If you know which point to monitor, maybe using a multi meter would be more accurate. You can try google up for "GTX 260 voltage mod" and most of the time there are guides/info on which point to measure voltage.

I've tried using Nibitor to edit my card's BIOS but there isn't an option to select higher vGPU

Your score is fine and I get roughly like what you're getting too.

Yup, I don't seem to see this option for my card. Any ideas? I'm using XFX GTX 260.

I've done that but I can't seem to see it I followed exactly the guide and got my BIOS from GPU-Z

Ok, I had version 5.0 but maybe that's what matters? I thought newer version would have the same functionality?

Load temp 66C with how many % fan speed running? 100%?

Something has to be done with the cooling before we go for higher voltage. More voltage but terribly hot won't get it anywhere better.

LOL, no money plus I'm an old man and no longer talented. You should demo to me next time

That's pretty good I have 740/1560/1160 during Far Cry2 at 70% fan speed but my load temps are already 71C. Nevertheless I'm still thinking of getting a full WB for this card.

If you want more score then go for 3dMark2001.

After that you'll have to worry about the cooling You don't want to run happily 800Mhz Core and in the middle of your game, the screen hangs

You mean it does not support 1Mhz incremental?

Are you using the latest 185.85? If so, please set the correct Forceware version in "Power User" settings. I'm using Vista 64 and manage to do simple functions in Rivatuner 2.24 despite the latest forceware not detected automatically.

I'm glad you've found it and is working now Happy overclocking. I actually prefer Rivatuner over any other tools since it's simple and easy to use.

The Palit GTX 275 seems to be pretty cheap @ RM899

That's true If we're an existing GTX 260 user then might as well go for GTX 285/295 instead if there is a need to upgrade.
