R640 DIMMs failed the memory test

Hi All,

I have recently bought a used R640 and installed a 16GB DDR4 2933MT/S (Dell Product number: SNPTFYHPC/16G) memory stick.

BIOS Version: 1.4.9

It shows the below  critical error message, while booting and not processing any further. Attached a screen capture as well. 

Tried reseating the stick and used another same spec stick, but the same error popping up.

Appriciate your suggestions and ideas

Thanks!

Critical

No memory found

All channels have been disabled due to all DIMMs failed the Memory Test. Verify the DIMMs are properly seated and that they are installed in the correct sockets!
