the best way to do it is to drop your multi to 10, up to fsb to 200 and run it tin sunch(1:1) mode. and if you want to oc the proc further than that you can up the fsb some but you will be limited and if that still isn't fast enough on th proc side then you can up the multi to 10.5 or 11 or whatever your chip and mobo can handle. you sould easily be able to get ddr400, 2.0-2.3ghz out of it. once again the biggest factors are the chip which si really unpredictable, the rram which seems like it should be ok to get ddr400 out of it, and you cooling. your cooling must be adequate to get his out of it.
