My HP Z840 has a single CPU - a XEON E5-2623 v3 - and has provision for adding a second CPU.
My problem is that HP has several Part Numbers for this XEON depending on the equipment it is in eg 790093-001 when referring to the HP Z840; 780762-001 when referring to the HP Proliant; and J9Q18AA when referring to adding a second CPU kit for the Z840.
So my question is simple:- is every XEON E5-2623 v3 identical no matter what its HP Pt No or piece of HP equipment it comes from?
The need for asking the question is also simple: most of those available are "Pulls" from servers which I presume are being scrapped; and the J9Q18AA kit is generally unavailable.
The kit comprises the CPU plus an additional heat sink and an additional fan.
I've managed to establish that the HP Pt No of the heat sink is 749598-001; and that of the fan is 647113-001
and hence may be able to buy them separately. BUT there are numerous fans supplied by HP which have different dimensions - and I have been unable to establish the dimensions of the 647113-001.
