I have a sorta noob question regarding a Gigabyte ex58 ud3r non a series motherboard.

I have a xeon hexa-core cpu and am trying to get a decent overclock but i can't seem to get the bclk past 220.

Is there something I need to tweek in the bios to get it running past 220, or do i need to upgrade my mobo?

And if so any recommendations on what motherboard i should pick up?

I was considering either the classified or the rampage 3.
