Having to run in yellow dimms being as ornage refuse to run dual channel and the board also makes a whine noise when under load. Done all this from the very start. Maybe time to RMA.

Edit: I can get 3.2 with no voltage increase, after that then it seems voltage has to be used.
not all e6600 of any stepping will hit 3600..and I find going from 3420(1.4625) to 3507 needs 1.52v..about .06...big jump

you will need to boost vcore and as you increase the chip may need a fair bit more vcore to hit that speed

also as you increase fsb the NB will need more volts

I would suggest setting vcore to at least 1.5v and see what you get ..but increase NB to at 1.42v to help reduce the chance the chipset is a factor

the bolded values will help alot in most cases...give extra voltages at first and then you can tweak them
