yup...
i had a fluke
i had put some silly ioh/ich voltage and then was booting 220 bclk

then later i thought lets to do the basics from 200 to 220.. and started undervolting the ioh/ich ( thought it wasnt important)
couldnt reach 220..
so retrace back and found it was the ioh/ich ..of course the vtt is correlated.
try it..
222 no post
max on this board is 221 for my proc.
also here is where it ends up being 220 = 219.8 , 221 = 220.8, 222=220.8
