***ASUS Rampage IV Extreme Owners Thread***

At those frequencies you will be pulling a shed-load of current, I'd make a crude guess at peaks in excess of 25amps from EPS 12V under full load (maybe more as processor temps increase). It's not surprising you can't quite find full stability.

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!
