I have a lightning. if you unlock the non-LN2 bios its 1.2125v max the only way anyone's getting more is using AB 2.2.3 which works in an odd way giving you only one chance to accurately adjust a voltage offset (only after a clean boot). This is fine if you want to run benchies but for normal use it's insufferable. I don't want to push much harder than ~1.24v anyway, when my full cover block arrives, I think I'll be ~1293 and +750 mem BF3 & everything else stable which is plenty for my needs (currently at 1280/+750 stable on air).
