ok here is the trick
first get the vcore stable first of course with lower qpi and lower ram bandwith
once thats the confirm stable

then confirm ure ram setting with lower uncore

for 4000 uncore
the trick is balancing the ioh voltage /ich voltage to the qpi
so far found ioh must be always set higher than ich roughly 0.4v difference
and setting 1.28v in bios will result in 1.24v

if voltages is in sufficient for ioh/ich say i set at 1.139/1.1v will result in 1.11/1.11 which is stock..
during 4x memtest hci around 400% or so two of them will result in errors.
and the ioh voltages will suddenly increase automatically to 1.24v in probe read and according to turboV 1.28set.

also u can tell from the bsod and error..
usually bsod is when qpi voltage is way inssuficient
and error is because of some off setting.



well ive so far gone right up to 221 bclk.. anything higher not possible as the bios doesnt allow me to do so.. setting 222 will result in 221 only..
no idea y..
also after 200 bclk every increament of 1 is 0.8 bclk read.. no idea why thats happening also.. so so far 210x20 will result in 4195.8 approximately..
