DL580 G4 processor upgrade

[Stanislav_3]

Hello
I have DL580 G4 server with 4x7030 processors. I have found, that I can install 7140M processors instead. I have found some in another city, but it's only processors, no heatsink and VRM.
I have found this info:
Model___Speed___L2Cache___FSB(MHz)_TDP(W)
_7030___2.80____2x1_______800______165
7140M___3.40____2,_16L3___800______150
So TDP is lower for 7140M.
Can I install only 7140M processors instead of 7030 without changing VRM and heatsinks ?

and another question - is there any difficulties with installing processors with different codes (like SL7DX or smthn like that) ? I have found a thread with w2k8sp2 troubles but for another proliant server.

Stanislav-
I can only help with your first inquiry. The heatsinks and VRM's are the same, so if you have the chips available, there no problem swapping them.

As regards the Intel sSpec number, the SL7DX (D0) and SL7PF (E0) should work together in the same system. I am not sure what the other post stated regarding the Windows 2008 Server issue, so i cannot address that.

Good Luck!
