R420 from 2012 : Upgrade CPU

Hello,

I'm sudent, and I just buy 4 old R420 servers, with couple of e5-2430 and 2450.

It seems it's "v1" cpu on 1356 socket.


They works correctly, but I want to max it.

I found the upper cpu for this plateforme : 2470 v2

I found it for 20$ each.


Can I upgrade cpu from V1 to V2 ?


I just upgrade bios and Idrac to the last available versions (2020 approx)


Thank in advance !


(P.S. : the power unit is 550w, so I think there is no pb of consumption).
