Happens.
A friend has several of these. He picked up a 2.3DC with a bad psu, which sat until he picked up a 2.0DC that was fine.
Of course, he wanted to fix the 2.3, so he swapped PSU's and parts.
The result? The 2.3 CPU only works with the board that was in the 2.0. It won't work with the board that it originally came with. And right now you're thinking bad LB, right? Except the 2.3 board works fine with the 2.0 CPU.
Explain that, lol. These things are just finicky beasts in general.
In short, I'd pull the second CPU (if its not the top one, put the good one as the top one or it wont run) and run it as a 2.0SP for a while. If it holds up, then consider a CPU replacement if the machine warrants it.
You could also try a processor reseat.
