570 sli bios editing

[Guest]

Here's the situation, I have two zotac synergy edition 570's (the ones that are slapped on to a 480 pcb/cooler) and I have already modded the bios with NiBiTor allowing for a max of 1.213v, with this I can achieve 960mhz stable on 3dmark Fire Strike, but i've been left craving for more!!

 

I cannot get the Nibitor regular voltage editing open (greyed out) only the tool's that allow max of 1.2v, and Fermi BIOS editor says the device is unsupported. 

So far I've tested to save the bios as .bin instead of .rom but no difference there. 

 

I'm not ready for stepping on the world of hardmods since i'm lacking the tools for such things.
