have a barton 2500 with AGXEA stepping

i successfully OC'd to 200x11 at 38c, my fsb/dram ratio is on auto-synch so my ddr433 rated ram is running ddr400

im feeling confident enough to step it up a bit so how should i do this?
216x11= 2376Mhz/ddr432 is what i was going to do but wanted verification if this is best...

also can someone point me to some good benchmark/stability/cpu temp programs?

thanks
