I use memtest, 3dmark, and prime. Memtest and 3dmark tell me if my overclock is "desktop" stable, and prime tells me if it's actually stable. I run prime for 8 hours, which sucks if I am trying to fine tune things. That's why I use the others first.

Before overclocking or unlocking cores, I ran two passes of memtest with both sticks installed, then ran 8 hours of Prime95 with no glitches. The core temp was running between 53*C and 55*C during the 8 hours of Prime95, according to HWmonitor.
I unlocked the 4 cores. the CPU won't give temps with the cores unlocked. The motherboard sensor indicated 36*C. I then started Prime95. Within 60 seconds, the temp increased to 62*C and climbing, so I shut down the test.
It looks like I need a better cooling solution before torture testing the quad cores.
Alternately, look into the voltages. A small drop might make a big difference in heat output.
Are you using the stock cooler? If you are, you could check out frostytech.com for info on coolers.
I'm a noob, so of course I'm using the stock cooler! I've been looking at the Sunbeam Core Contact plus a couple 120mm fans. I have pretty lame case cooling with just one small (80mm or 90mm) exhaust fan in the back.
So you are saying that if I drop the CPU voltage a little, that will substantially lower the heat output?
I would get the Sunbeam Core Contact (or another good HSF) before I would try and unlock the 4th core. The stock cooler isn't going to keep your temps down good enough through the overclocking process to unlock the 4th core... temperatures will start to be an issue.
