It sounds like you're running into a roadblock with the BIOS. It might not be updated, or even made at all to support that processor. However that's just my best guess- best to wait until someone who's actually messed with these particular machines.

If you do know for a fact that the computer will take this processor, then my best guess is that you need a BIOS update, or modded BIOS.

I think that I have got latest bios on it. I download bios update utility from lenovo web site. But when I start it I have got a massage that the bios not need to be updated. Where I can find moded bios?

There's no modded BIOS for R50e.

Have you tried that PM CPU in another machine, just in case?
