Question on oc'ing my e6600

[gizbug]

Have an ASUS P5N32-Sli-Se-Deluxe MB.
Have an intel dual core e6600 2.40 processor.
Right now I am oc'ed to 2.70. Would like to go up to around 2.9 or so.

Not sure what I need to change in the bios.
Currently I have :

System clock mode: manual
FSB: 1200
Memory clock: 667 (as I need to run my memory at 667 for compatibility reasons).
I see no muliplier. Do I need to increase the FSB to some other value?

Also, I have enhanced C1 control set off. That should be left at off, not on, correct?

just ran cpu-z and it says:

core speed 2700
mult: 9
bus speed 300
rated fsb 1200

In my bios it shows a manual entry of 1200
I didn not see "300" listed anywhere in the bios.

i would run the fsb @ 1333mhz to get 3ghz even, while this will allow your ram to stay 1:1 @ 667mhz. nvidia's boards make you input the effective bus speed when you are overclocking, so just divide that number by 4 to get your bus speed.
