Hello,

I recently bought a DELL PowerEdge T140 server, which didn't come with RAM. Consequently, I had to buy RAM separately.

The RAM I chose is the KTD-PE426D8/16G, which is a DDR4 2666MT/s ECC Registered DIMM, and should be compatible with my server as per the manual. Despite this, the server won't boot up and displays a critical error indicating that the RAM stick is unsupported.

Critical
Memory Population Error:
Please remove unsupported DIMMs from the system.

Attached are images of the error message and the RAM stick in question.
PS: I made sure to stick the RAM in the appropriate slot.
