Donno. Or cpu is this sucker. factory default 4th core is weak as f...ck. maybe thats the only limit. I tried with psc and micron gtr but eff was shit both times.
I think its a bios bug. When I use factory default 4 cores it is eff 1.0 when I use 3 factory cores and 1 unlocked to get 4 cores total,performance drops to like 10-20%. everything is the same.
