I would suggest
Aidia32 for a monitoring program.
What motherboard do you have?
What core are u r running?
I took my 2600+(tb B) with the same hs/f as you and could get it to 2.3 stable at about 95 idel.
For OCing try lowering your mulitplier to 11.5 and put ur FSB to 200 crank ur voltange to 1.725 that should make a stable setup. Thats what my friend and I are running right now.[
