If you remember my post regarding 4600MHz LinX stable on air a few pages back, I got this in a case of despair by undervolting CPU PLL to 1.4v and QPI PLL to 1.0v.

Now and just for fun, I undervolted almost every single voltage on this board and went for a run at 4500MHz



I guess I can try and lower them some more, this was just the first try!
