vdimm at 1.75v is much more safer then cpu nb volt at 1.5v. even 1.35v is consider high for some.
so better pump up vdimm and tune down vIMC.
Will do it...trying to lower cpu-nb and raise vdimm thx
Added on February 4, 2012, 4:34 pmI have instability issue (BSOD) when i change cpu nb volt from auto to 0.5(1.17v)
So i started oc from scratch:
1. CPU-NB + RAM oc (STABLE)CPU 3400Mhz auto
fsb 255
RAM 1700Mhz 1.6V 9-9-9-24-1T
CPU-NB 2550Mhz 0.15(1.277V)
NB 1.275V
HTL 2040Mhz auto
2. CPU + CPU-NB + RAM oc (STABLE)CPU 4032Mhz 1.46V
fsb 252
RAM 1680Mhz 1.6V 9-9-9-24-1T
CPU-NB 2550Mhz 0.15(1.277V)
NB 1.275V
HTL 2016Mhz auto
Will try to play with timings when i have time soon...
