I unlocked my X3 720 to 4 cores and its running stable @ 3.6GHz (1 hour of Prime95)

Right now my CPU is essentially an X4 940 as I'm running on an AM2+ board. So...

Now I'd like to get the clocks up higher but 18x seems to be my limit. So I set my bus speed to 212 and I'm currently @ 3.8GHz but that's crashing and unstable. I'd like to eek out a couple more MHz before I call it quits and I'd especially like to get 3.8GHz stable so has anyone got any ideas.

Bump up the voltage if you have good cooling. Monitor temps and if they hit higher than 55 on any core, drop voltage so it won't get as hot.

you cant monitor temps as the sensors go once you unlock the 4 core
@ OP try 1.52vcore bump the NB volts up slightly and try for 3.8GHz

I have NB at +.1V should I try +.2V?

CPU Voltage is at 1.55V in Bios, That's keeping me stable @ 3.6GHz

Try not to OC the 720 using your fsb, they seem to want less power if you use the multiplier. I got mine booting to 3.8ghz on all four cores this morning with 1.55vcore, +0.2 on the northbridge and my cpu-nb set to 1.3.

Upping your southbridge by say +0.1v may help out a little with stability as well.
