Dell R640 Mix Memory

Hi Currently my dell server comes with

128GB x 4 = 512GB

I would like to make my server with 2TB memory

can i mix memory configuration

128GB X 8 = 1TB

64Gb x 16 = 1TB

my reason is 128gb memory is highly expensive so I choose 64gb instead.is it possible?

You can mix memory of various size but both need to be from same family. I assume you have 128GB LRDIMM then you need to have LRDIMM of 64GB also. Can you share part number of 128GB and 64GB Memory you are planning to use.

You can also refer below link for details on memory module installation guidelines
