CPUs don't store the history of what speeds and voltages they've been run at. Try overclocking it without raising the voltage. If you can get quite a few more mhz out of it (say, at least 2.9-3Ghz) without adjusting the core voltage, it's still in good shape.

It's not strictly fair to assume engineering sample CPUs will have been trashed, my engineering sample 4870X2 has been well looked after. Don't, however, expect that little test to be comprehensive. It only tells you what state the chip is in now, heavy voltages exercised on the chip in its previous life could potentially cause problems later. Usually though, if it hasn't already gone bad, as long as you keep the voltage safe, it should remain as it is now.
