I never measured it when i soft volt-modded, after testing that BIOS i just hard volt-modded then flashed the 878 speed one i made for myself after making sure it's stable at that speed, used 1.4v for it.

But if it's stable at that voltage then it might be just a v-droop, or so they call it, though, i only heard about it related to Motherboards, don't know about VGA, it's not necessarily and bad thing, but anyway, to get more voltage you have to hard volt-mod.

Download the BIOS i made for you again please Chuk, i editted it, i made a tiny harmless mistake before, but corrected it, if the first one is working then nevermind .
