Well damn, that saves me a bunch of trouble! tongue.gif

I'm confused though, does 2.3.1 not let me do it?

no, not out of the box , 2.2.3 does .

you can get newer versions to work but you have to search for the lines needed for your card to add to the profile config file . I only know off hand ones to 660ti PE .but they have been posted over at guru3d forum

Well I downgraded, and bumped my voltage. Not really seeing much of an increase

The max you will see is like 36mhz , don't go by voltage displayed in any app like GPU-Z or even AB (AB I have it disabled with mine) as that is not really the voltage .

how I check if version is working, is to note the power % with a repeatable type BM , Heven, furmark , valley etc . if voltage works you should see the power% go up if say you raised it to 70mv .

For me I use the voltage to cheap it from lowering at times . On my card (660ti PE/OC ) it will lower from 1.175 to 1.162 at around 53c it seems in Valley for example . so I just raise slider 10-20mv to try and keep it in the 1.175- 1.18xv range . Again you can measure it so just add what you add in slider to what is show with it at 0 and should be close .

should allow you to bump up clock stable a few multiplier (13+ each) .

Don't expect big jump with this or even bios unlock it can only go/do so much for each GPU chip/card .
