This must be why no voltage over 1.49 seems to get it stable. Do you think its spiking without seeing it? Because once on phase it handled even lower voltage.

On another note...

A buddy of mine and I are both trying to hit the 166 Blck. He has actually been able to get through post on his UD5 and freezes going into windows. I have the R4E and I tried it once and got 00 code no post at all.
So, I went looking through the Bios to see what auto sets and notices that it sets the CPU I/O to -63 and the CPU I/O Drive strength to -63 as well. Could this be hindering me?

I say this because when I first set the preset Normal OC profile it had the PLL all the way down to 1.35 and it would not boot. So I reset and went back into the Bios looking around and put that setting back to 1.80 and booted with that being the only change from the OC normal Profile.

Any reason for Asus making these Auto changes in Skews when a 166 strap is used? I cant seem to find anything related to what these settings actually Skew!

Doubt those settings are hindering you, we auto-set for you to make it easy as possible. Some CPUs will not POST at 166 BCLK and there's not much you can do about that. You can try setting 155 BCLK and starting from there.
