you want a good combination of oc'ing the fsb and multiplier, but tbh i think you'd be better off spending 60 bucks on a 2800 amd and oc'ing that up to 3200if thats what you wanted to do, and your ram is holding you back loads, 2100 is probly worth more in scrap metal!
what i'm basically trying to say is your flogging a nearly dead horse, but a nearly dead horse that could be back up to show condition for not a lot of dough.
And what cooling have you got in your case and on your cpu, i do hope your not doing it with stock stuff :\
