I have a Dell Poweredge R440 with 2 Intel Xeon Silver 4108 1.8 GHz CPUs. I needed to upgrade them to the 4208 2.1 GHz so I could properly run ISE on the server. But when I removed the old CPUs and installed the new ones, I powered on the computer and during the boot process I got an error that said that there wasn't any memory installed.
Considering there was 128GB of RAM plugged in, all recently tested and working....I had a feeling the CPU was the problem. When I put the old CPUs back in, the server booted just fine.
I've seen these Dell servers sold with the 4208 CPUs in them so I assume they are supposed to work on the computer. Is there something special I'm supposed to do to make them work? In my experience just plugging in the CPU has been enough but this time seems to be different.
Thanks for your time.
i confirm, when installing a new CPU there are no modification to do. In this case there is maybe an compatibility issue or the new CPU is failed. Did you test it in another server?T
I didn't test it in another server because this is the only one I have. However I did have 2 different CPUs and both of them, when socketed into the CPU1 slot, give the same error.
It seems highly unlikely that I would have 2 brand new CPUs fail out of the box. Not impossible, but unlikely.
I would recommend you update BIOS to current 2.8.1 (if not already) for updated processor and memory reference code.
Did you get the heatsinks for the upgrade?
Upgrading both CPUs. Must replace existing heatsink with 412-AAJQ (for CPU1) and include heatsink 412-AALK (for CPU2)
