cMP Processor check

[Razzerman]

Hello there,

I currently have two cMP's (2009 firmware update to 5,1). One is a single processor machine, one a dual processor machine with processors upgraded using the washer method (not delidded).

I may be getting hold of another dual processor 2009 machine, and the question I have is would it possible, if I ordered a matched pair of processors, to check each of the processors are working by testing them on the single processor machine, to make sure they work prior to delidding them?

Cheers,

Razzerman

To my knowledge:
Yes, you can check each of the Xeon CPUs in a single socket machine one after the other. What would not work: use two single socket CPUs (like W3680, W3690, etc.) in a double socket machine. BTW, matched processors are a myth. As long as it says SLBVX on the surface, an X5690 is an X5690 is an X5690. I wouldn't use Engineering Samples but those would have an ES on them.

Good news; thanks for the info

Yep, that's an excellent plan. I've done that w/ each of my delidding projects so far (some for my machines and some for clients). You really want to know that the CPU is working properly before you delid it and then cannot return it to the seller! In fact, since I have 2 client cMPs (and 4 CPUs) to do at once this time, and since I only have dual processor machines myself, I've actually purchased a single CPU 2009 processor tray at minimal cost (~$70), so that I can test them "lidded" first.
