Hi ,
first off i take it you know how to enter your BIOS ?
as soon as PC starts tap "delete" key.
Your looking to raise your FSB from 166 to 200.
and lower the Multiplier from (i think its 12.5) so from 12.5 to 11.
that should give you a overall 11 x 200 @ 2200 MHz 3200+
you should really do this gradually in steps like first drop the multiplier to 11 and up the FSB to say 180
11 x 180 @ 1980 MHz
then
11 x 190 @ 2090 MHz
then
11 x 200 @ 2200 MHz
and make sure you set your RAM to 100% or 1:1 so your at DDR 400 .
if it does 11 x 200 @ 2200 MHz easy and passes benchmark testing then try and up the FSB a little bit at a time until it gets unstable and then drop it .
Baically find your breaking point then touch off the gas a little , and your good to go.
if you have any problems also try adding a little voltage that solves it most of the time
but i wouldnt go above 1.8 ... thats me personally ... it will put your temp up way high.
EDIT :
please let me know what motherboard your on , and what vCore , vDimm and RAM settings your running if you can
