Fermi BIOS editor + GPU-Z BIOS export; Need OC help

[runit3]

So I've finally gotten around to using Afterburner to start benching/OCing my GTX 580's (SLI) and I'm running into some issues. I can hit stable clocks on most benches, but they vary quite a bit between Valley and Cinebench. Pushing 1.15v through Afterburner but that's the max

 

Looked up some BIOS tweaks and got my hands on FermiBIOS editor 1.55 and NiBiTor v6.03, GPU-Z exports my BIOS just fine but whenever I try to open the BIOS's within both applications it has all the fields as blank.

 

Anyone have a suggestion for how to get them to load properly? or is it just because I'm working with relatively ancient software for equally old cards while running 344.11 WHQL release (the only release that enables SLI for me, or at least that I've found after testing 3-4 old driver releases).

I would be interest in this as well. I'm gonna be getting my hands on some more 580 in the near future and would like to get some more clocks out of them.

Afterburner works great up to the 1.15v mark, but I've got them under water and max temp is 53C after 20min of extreme Valley HD, could easily throw another .05v at them to get over the 1000MHz clock hurdle
