Setting up RAM correctly when oc'ing.

[Michaeljcox24]

If I set up an FSB of 1200 on a quad core Q6600, do I need to set the RAM at 600MHZ? I have two sticks of DDR2 in the machine (800MHZ) but they only run in single channel mode.

1200/4 = 300
300 x 2 = 600

Or is it ok just to leave the ram at 800MhZ as per auto setting?

the machine wont boot when i put them in the dual channel slots. Board must be dodgy but at the moment i dont have the time to do a rebuild with a new board.
ive put the right voltage in, 1.85v. ram is rated at 800mhz. In the bios, there is a box you have to fill in for memory speed which is underneath the fsb you want to use for your overclock. ive got it set as 'unlinked' because when its linked the memory speed goes to over 800 and the machine tdrs in games.
at present its a Q6600 and the max overclock i can get is 2.7. seems low compared to what everyone else gets on this chip and i wasnt sure if i had set memory up correctly
