Hi JOceon,

thx for you answer. As i understand it, there are differernt mainboards which support different cpus.

I want to know which cpus is supported on the X8DXD board.

Hello,

this thread

https://www.dell.com/community/Precision-Fixed-Workstations/Which-CPU-for-0X8DXD/td-p/8193599

answers ( xeon W , in short ) in detail

The board X8DXD will support Intel Xeon W-21xx, and some W-21xxB.

Hi,

thanx for your answers. I mismatched the boards. The X0... was inside before. The board which is the one now is: 02M8NY.

Sorry ´n cheers, Pit

The board 02M8NY will support Intel Core X series processors.

Dell Inc. Precision 5820 Tower X-Series - Geekbench Browser

this suggests it should support i9 10th gen (note the "should")

I have the 02M8NY motherboard with a i9-9820X currently. Will This motherboard support an i9-10940x ?

Thanks.
