Help me to OC this 3.2

[popcorn]

MY system;
IC7-g mobo
PIV 3.2 bus 800
Corsair PC4000
with WC

I can run it @ 235 with vcore DF, temp about 43*, stable, full load 24/24

It cannot run stable @245 even vcore @ max 1.7

Any suggestion???

I need it to run at least @250

235 fsb is over 3.7gig...I don't think you'll get it any higher with super-cooling....that's a damn good overclock....
