OK i started back at 333X9 all at stock levels.

Let's say i were to increase the FSB to say 340 and it fails, most likely i will be increasing the vcore. Let's say that it fails as well, will i be increasing the vFSB or vMCH ?

How do you know which one to increase? vFSB, Vcore or VMCH? You have to juggle with 3 probabilities here.

Left my memory at 266:533 (1:1) and vdimm at 2.0V to underclock it and to focus more on the CPU first. Is this correct?
