Not a very quiet system I take it?
Are there any advantages / disadvantages to changing the multiplier not the FSB?
356x9 is about the same as 400x8 - but at 1:1 Ram - that would give me a much better clock (although apparantly at 1:1 I am on 1333 Strap not the 1066 Strap - whatever that means).
your CPU will throttle if it gets to hot which for your Q6600 is @ 95c.. really up to 65c is no problem.. again do not worry to much about the vcore is heat that damages the CPU not volts..
