Tweak a GPU

post #1 of 2
Thread Starter 
I am being shipped for free a geforce 560se from amazon for my troubles, with 2 dead motherboards with 2 broken voltage regulators (I used 2 seperate PSU, one for each build, just to be sure) that fried 2 CPUs (They had a bad batch of the ga-b75m-d3h), since after I put my old geforce 260 on it, now the geforce 260 has a permanent capacitor whine.

Regardless.

On my old geforce 260, I used riva tuner to lower the idle clock from 300mhz to 150mhz, and I cut the memory to 120mhz
The voltage was locked at 1.05v

I want to save some power this time. I'm making the assumption that the EVGA model has a voltage that can be changed.

What are the best GPU voltage tools?

Is GPU undervolt similar to CPU undervolt in methodology? I've done a -1.875v offset undervolt on my CPU, so I'm used to that concept.

What are the differences?

I use MSI Afterburner, I like the interface a lot better than both EVGA Precision and RIVA Tuner.
The 5xx series are voltage unlocked. I haven't bothered downclocking my 570 since it comes with an idle function of 50mhz and 0.9v. It may be the case with your 560se as well, I'm just not sure smile.gif But fully customizable voltage using Afterburner anyways...

The concept is similar, yes. The methodology is similar in many ways as well. You underclock it too much, your'e gonna have a bad time! In terms of instability, driver crashes, occasional BSOD's and that sort of thing. Make sure you test for ever 10-20MHz you go down (or up).

A difference might be that you won't notice the underclock as much on your gpu versus your cpu. This is a hypothesis, I haven't done any testing or read any tests on this subject.
