Abit NF7-Sv2 D26 CPC-OFF mantarays-xt is the exact name of the BIOS we have which can be found here:
Has quite a few BIOS's so it could be worth it to read up on the one that might offer you the best stability. The one we have is the most up to date and features a lot of the previous features of the modded BIOS he made so basically with thist latest one you're hoping for a nice collection of all the things you want in the BIOS such as ROMSIP tables for higher FSB's, Soft L12 mod for Tbreds and mobiles that attempts to unlock the processors that aren't 'super locked' but really the only way of getting one of these is to just get a mobile now-a-days
Also this particular BIOS has a much nicer layout and all the options you need to overclock are in the same menu.
Just make sure you're comfortable with flashing your BIOS because it won't be like a magical end all problems BIOS or anything like that. It adds a small amount of stability and functionality so don't feel you HAVE to flash it to that.
But if you've flashed before a million times and had no problems then you should be aright
