GTX 650 safe voltage?

[AquaDash]

I'd like to overclock my GTX 650 to get a bit more performance (enough to match a 7770 in games) and I want to know the maximum safe voltage that can be used for this GPU.

Hi and welcome to Tom's forum.

What software are you using? Any way, all the current applications that give you the possibility to overclock the GPU are limited to some secure voltage level, so, you can go until the max voltage that your application give you and your GPU will be safe.

But keep in mind that with more voltage, you get more heat...

Yeah, I understand that. Currently, I'm using MSI Afterburner and Unigine Heaven 4.0 for some tests. I plan to run this GPU at 80C under full load (unless the GPU has a higher max temp than that).

What exactly model do you have? While 80°C could not be high, I would prefer keep the temps as low as possible, more if the performance that you gain with the overclock isn't good enough.

I'm actually unsure about the GPU, but it is an OEM desktop, if that helps at all...

Ok, not problem. You can start to rise the settings by 10-15MHz on Memory only and testing for stability.

Regard the exact question: "maximum safe voltage that can be used for this GPU" you are safe to go with the range that give you MSI Afterburner.

Wow, thanks for the help. If I'm lucky, I might get a few more frames from my PC.
