5 Module Types For Server Platforms 288-pin DIMM Registered DIMM Load Reduced DIMM ECC Unbuffered DIMM 240-pin DIMM Registered DIMM Load Reduced DIMM ECC Unbuffered DIMM Optimizing Memory: DDR4 is NOT compatible with DDR3 based systems (module will not fit) Install memory in kits of identical modules according to memory architecture Configure all processors the same way for most bandwidth Do Not Mix Module Types within a server. Mixing DDR3 (1.5V) and DDR3L (1.35V) will default the memory to 1.5V. 5
