Best E5200 overclockers - M0 or R0?

[VirtualLarry]

I've got two M0 and two R0 E5200s. One of the R0s is in the old style box, one is in the new style box. Both M0s are in the old style box, of course.

Which ones are likely to be better overclockers? I've got two rigs with E2140s, that I'm thinking about upgrading.

Try googling the batch of each and see if you get any results. Honestly though, the R0 chips will be just as good as the M0, if not better.

From results I've seen, I thought R0 was a better overclocker, then looked further back and they're about the same. I had an M0 and it wasn't that great, wouldn't break about 350fsb and had R0 envy, but looks like it was unfounded.

If you've got all three and they're already out of retail packaging, just test them?
