• The total number of DIMM slots for the Z840 is 16.
• The Z840 will support 4GB, 8GB, 16GB, 32GB, 64GB or 128GB DDR4 Registered.
• This server will also support 32GB, 64GB or 128GB Load Reduced Modules (LRDIMM).
• The Maximum amount of RAM the Z840 server can hold is 2TB (16 x 128GB) of Registered DIMMs (RDIMMs) memory.
• The Maximum amount of RAM for Load Reduced memory (LRDIMMs) is also 2TB.
• When purchasing new memory it is best to purchase identical memory modules to what your system already has. Your current server configuration will determine the supported DIMM type and speed.
• The Z840 runs on 2133MHz or 2400MHz memory.
• Think Long Term! Purchase the maximum amount that your Z840 can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.
