My board likes a little bit less then 67% x Vtt let's trade some feedback to see how it plays on the P45.

Anyway thanks for the info and have a good night.
I haven't got it nailed completely yet & its only about an hour stable but my chip has roughly run 4GHz 1.216~1.232, 4.1 @ 1.248, 4.2 @ 1.28~1.296 & I'm currently good at 4.3 with 1.328~1.344 loaded according to CPU-Z so its scaling nice.

Haven't touched PLL yet & don't intend to, call me chicken but I've wrecked good chips with PLL & despite what anybody says here on XS about killer voltages IMHO PLL hurts & I'll stay away from it.

My CPU likes 0.67 & so did my NB to a degree but I found I can dramatically reduce the VTT needed by raising NB GTL to 0.69

@ Thule welcome to XS

I would try all GTL's to 0.67 & give it 1.25v vtt then see what happens.
