How do I tell if my cpu is cdo or cco without pulling off the heatsink?

[TUK101]

I was wondering how to tell if my cpu is cco or cdo without pulling off the heatsink. The reason that I dont want to pull off the heatsink is because it was a B*tch to put on, it fits very tightly and I dont want to unnecesarily take it off and put it back on in fear of cracking the core. SiSoft Sandra just reports that my 800 Celeron is just a CO. So that was no help. Thanks for any leads or info. :cool:

Voltage? I think(Edit: I KNOW) that cBO and cCO were different voltages.
My cCO celly is a 1.7v. says so right on the chip.

Intel cores are pretty strong. If I show you what a GOrb did while I was plauying around with it you would be surprised that it still posts klet alone fully boots and runs @945mhz!

Cpu-Z will tell you.

Also the default vcore voltage is 1.75 for cD0 and 1.70 for cC0.
