4670K & 4770K both need 1.325V+ for 4.4 GHz.

    How is this possible?
    My old 4670K wouldn't break 4.4 without 1.325v. I just popped in a 4770K and it won't do 4.4 without a solid 1.35.

    I'm running uncore at 3.4 GHz 1.25v, vccin 2v.

    This is a rant post.

    Not uncommon for pre-refresh haswell chips. Both of the 4670k's I had were pretty much the same, one could do 4.6 @1.35v if I remember correctly. Then got a 4790k & 4690k that both could do 4.8 @ 1.35v, was the way to go.
