Overclocking AMD Phenom II X4 955 Black Edition. Help needed.

post #1 of 8
Thread Starter 
Want to oc to 33.6GHz from 3.2GHz only I've not much of an idea of the best way to go about this as I've never manually OC'd before. Specs are:

CPU: AMD Phenom II x4 955 Black Edition 3.2GHz

GPU: Palit nVidia GTX460 1GB

Memory: 3x Kingston HyperX 2GB 1600MHz

Motherboard: Gigabyte GA-MA78LMT-US2H, 780G chipset

PSU: 500W (forgot brand)

Cooling: Corsair Hydro series H50 or H55 (not actually sure as got from a friend)
4x 120mm case fans

Core voltage is currently 1.456 volts.

Not sure what else I need to include so any pointers would be appreciated.

You actually prolly wont need to do anything for 3.6GHz just raise your multiplier till it hits it and run prime for bit and see what happens. But like i said you shouldn't need to touch voltage till 3.8ish (and is it c2 or c3 stepping)
Anybody is free to correct me if needed.
Hope this helped thumb.gif

pretty sure that's the same board that pioneer blew up..I wouldn't OC on that...

The pinoy goat would not approve of overclocking on that board.
edit..maybe you can lower vcore a tad and OC as much as that setting will allow.

I have had my x4 C2 Deneb at 1.375 (1.360 during load) volts via its B.I.O.S. for its cores at 3.222GHz and 1.275 volts via its B.I.O.S. for its uncore/C.P.U.-N.B. at 2.215GHz with my old MA78LM-S2H that has but 3+1 phases and no V.R.M. heatsink(s) since 2009.

@ Schmuckley: That was the MA78LM-S2H, this is the LMT. So, that "high fail rate" may be a mislabel. On the other hand, these aren't high quality VRMs for a 4+1 phase.

I neglected to state that my motherboard was the MA78LM-S2H, so thank you! I edited my post.
