C_N:
You said that LLC1 was overvolting when you crossflashed:
Did you try reflashing with the non modded B3 BIOS instead?
Just wondering (wanted to make sure), because I remember someone in the UD7 thread saying that when you crossflash the B2 board to B3, PLL Overvoltage doesn't work at all, until you flash it a second time (with a normal B3 bios).

(I mean it is worth a try...I don't want to post in another forum claiming that B2 and B3 have actual VRM changes unless I'm fully sure...)
