Heres where I am now....

Core voltage is at 1.258v

there you go nb vcore that talked about is called as qpi ppl vcore raising that to about 1.35v would be good enough for about 3.8hzh- 4.2ghz until you need to raise it again. btw it little bit sounds like your ram is holding you back while ocing your cpu.
