Hi there I have had my workstation for some years now & I wanted to upgrade it so I looked at the HP web site for Z820 Workstation update CPU.
I bought two Xeon 2680 v.2 + 64Gb extra memory & I ordered a cooler for the cpu of course.
Now I put in the new ones, the fans runs with maximum rpm but nothing on screen. So I tried to try one cpu at a time and different ram combinations but it wont work.
The bios is the latest so what is the issue because I now got the Xeon E5-2620 with motherboard version 1.01.
Does my workstation support Xeon 2680 v2 10-core ?
Thanks

You need to use the search bar here to look up the two different Z820 verisons. They have different boot block dates which you can see in BIOS under the first tab. If you have a version 1 you cannot run version 2 processors.
Do you know if those two matched processors are on the approved HP listing of version 2 processors that will work in the Z820 v2?

the E5-2680 (Sandy Bridge) is supported in a z820
the E5-2680 v2 (Ivy Bridge) is supported in a version 2 z820 motherboard
The first generation Z820 using the Xeon Sandy-Bridge processor supports up to 128GB of 1333MHz memory.
The second generation Z820 using the Xeon Ivy-Bridge processor supports up to 512GB of 1866MHz memory.
Gen I systems:
Will have a Boot Block Date of 12/28/2011 (sandy Bridge CPU's Only)
Gen II systems:
Will have a Boot Block Date of 03/06/2013 (can run sandy/Ivy based cpu's)
