I know this is an old'ish thread, but i couldnt find any others regarding this Board (Gigabyte GA-N680SLI) and Quad Cores at least.

I have this board running with a Q6600 and like others around have hit a BIG FAT wall at around 320fsb. From what i can gather from info on teh net and other people it's due to the GTL Ref Voltage, that is not allowing the Quads to use higher FSB's.

I have all teh gear needed to push this sucker higher (see sig), hopefully there will be a fix and in a future revision (bios fix unlikely) or some Guru can work out a good volt mod and details for it on this board.

The Q6600 sits @2835@315 on 1.2(1.16-7 real)@60-65c (CoolerMaster GeminII) and will Prime all day. Just dissapointing they hyped the Quad Core Optimised 1333fsb, NOT!!.

Sry for bringing up an old thread though hopefully more people have this board now and using quads and possibly work something out.

Cheers
