U've unlocked multi, just keep ur rams settings at stock, then push the multi higher and increase vcore to get stability. WHen u've found ur proc's highest speed, then only u tune the ram speed and balance it with the HT link.

By the way, if ur proc is the brisbane G2 version, dun expect high oc, if u were the 1st few buyers of the BE, u mayb owning the F3 version which will allow u to go much higher.
