core2quad Q9550 need some help

[terramir]

on my ex board I could run the thing @4ghz no problem, but now with my new board I'm having some issues, however witha core2duo this board should be capible of 530 fsb, so I'm thinking I have to tweak the other voltage valuesso there are the following values on this board:
CPU VCore
CPU termination
CPU PLL
CPU Refererence
MCH Core
MCh Refererence
MCH/DRam Reference
ICh Core
&
DRam Voltage
So what are the caustions and what do these values do?
Need some hints Up till now I was OC'ing at the most core2duo's and whith those I never had a problem

what was the old board?
What is the new board?

what was the old board? EP45T-UD3LR
What is the new board?EP45T-USB3P
I dunno but this board seems to have voltage regulators that undervolt a bit more than the UD3LR for some reason it's a bit more picky, maybe it's also that it has three items on the pci-e bus (the usb3) pcie 8x X2
I dunno but I do know I need to fine tune the settings and I dun wanna fry my Q9550 in the process
