Follow this guide to the "T". I got my XFX 5770 ZNFC model to 1000/1375 on 1.2v and I run 65% fan while I game, and never get over 65C. Also I'm using CCC 10.10e hotfix drivers on Win 7 64bit if that helps any.

Any idea which version of the ZNFC your card is?

Model number is HD-577A-ZNFC. It's a reference design which means it has voltage tweaking but it's not a reference model so it doesn't have 2 CF fingers.

It's this one.

I have the egg shaped ZNFC which Newegg sells and mine does not have voltage control so far. The voltage regulator on the card is not supported yet by any software except for RBE which can undervolt the card, but that's pretty much it.

Thanks for taking the time. +1 Rep!

I tried it and sadly enough, it did not enable voltage control.

Mine is the 577X-ZNFC VE.2 and the voltage regulator is the APW7088.

Other people running the ZNFC VC.3 variant of the card were able to unlock voltage control. Check my thread here: http://www.overclock.net/ati-drivers-overclocking-software/935275-xfx-5770-non-ref-locked-voltage.html

I do not like to hard volt mod it. I am getting 970/1350 at 1.1V so I am really happy and my FPS are very satisfactory.

Maybe the voltage regulator will be supported in the future.
