GPU Overclocking

[glennaxl]

For CPU, overclocking is done through the BIOS. How about the GPU? Where would you do it?

I was unaware you could over clock a GPU in the BIOS. How ido you get to the BIOS on a GPU?

I prefer the safe way to overclock my gpu, or should I say underclock it, through msi afterburner.
It's more easier for me, and don't want to push my luck too much

I use the EVGA Precision Tool on all of my GPUs.
All of my GPUs are EVGA....the tool may work on other brands with nvidia chipsets, but I have not tested that of course.

I use EVGA Precision too Mark and yes it does work on other brands with Nvidea chipsets. My little 9500 is an off brand and it works fine.

The last time I tried, EVGA Precision didn't work with Fermi. I take it that it does now? I will try using it again, as I would like to unlock my voltages. I may not be able to to it, as every tool I have tried won't let me. The 480's are from a company called Zotac.

I updated to the latest Precision version before trying it with my 465s.  I had not tried to use my slightly older version, but it's quite possible that it would not have worked before support for the Fermi cards was added.
And I have never tried to do anything with voltage modification.....as my cards are all using the stock cooling, they run hot enough the way it is.  With your water cooling setup you might get away with boosting things a little bit.....dunno.

I use this little tool.

With that you can make a shortcut in which you can put in your autostart which sets your: gpu clock, shader clock, mem clock, fan speed and core voltage.
It's so small and light and you get some statistics.

Didn't know how i could cope living without it if it disappeared.

Kind regards Vyper

Cool tool thanks.

+1 for eVGA Precision S/W overclocking... and SpeedFan just in case something goes wrong (like an AC failure) and I need to stop BOINC or shutdown the computer altogether

Well, for advanced skill the best would be the BIOS upgrade, but could not be done so much if is there no applications available for doing it, the best could be a mix of them.

Thank you msattler and Vyper for the information. I will try both products and see how they do. The question I still have is how do you get to the bios on a GPU (GTX 480)? I didn't know you could do that.

I tested both tools, and found that they both allow individual control of frequencies, but the Nvidia Inspector did let me adjust voltages. I had been trying to do that for months. I should be able to get 850 MHz or better. Temps are still cool, and voltage is kicked up a bit to see how it remains stable.

Try searching for nVidia BIOS, seems to turn up much pertinent info.

I posted it here. Its very straight forward - you save, modify then write .   Let me know if you need further assistance.
