latest for play will be updated here
have to remind you not to turnoff power/AC/Clear cmos when you see debug port ‘62’ or ‘71’ or ‘81’ during the updating of various firmware after bios update and let them update properly

Here is a tip for maximizing bclk:



First set Skew driving voltage to 1.04v, set bclk skew to 0 , rest of skew to auto and start pushing bclk to find limit.
next set Skew driving voltage to 1.04v, set bclk skew to -8 , rest of skew to auto and start pushing bclk to find limit.
next set Skew driving voltage to 1.04v, set bclk skew to -12 , rest of skew to auto and start pushing bclk to find limit.
if bclk is increasing going to -12 then slowly lower skew driving voltage from 1.04v to try to max bclk again.

for reducing bclk First set bclk skew to 0 , set Skew driving voltage to 1.04v,rest of skew to auto and start rewducing bclk to find limit.
next set bclk skew to +12 , set Skew driving voltage to 1.04v,rest of skew to auto and start rewducing bclk to find limit.
if bclk is redusing going to +12 then slowly increase skew driving voltage from 1.04v to try to reduce bclk again.

You have to install intel ME

The ME driver initializes the Management Engine for operation.

Boot Issues of 0675 fixed in 0077 ?

@ Pt1t

which boot issues? i have no problems with 0675

Btw is it possible that Sandy Bridge have problems with Elpida Hyper based memory? Or is it the MIVE (bios)?

my Corsair Dominator GT Kit run good with 1866 divider (up to DDR3-1980 7-7-7-21 @ 106.2MHz BCLK) but if i use the 2133 divider it can´t pass SPi32M (timings tested from 8-8-8-24 to 9-9-9-27), it freezed after a few Seconds.

My old HyperX Kit with Elpida BBSE run 2200+ CL8 w/o problems.
