Supermicro MEM-DR464L-SL01-LR21 64GB DDR4-2133 4Rx4 LP ECC LRDIMM server RAM

64 GB DDR4 server memory

The Supermicro MEM-DR464L-SL01-LR21 is a 64 GB DDR4-2133 LRDIMM built for enterprise servers that require very high memory density per slot. Its load-reduced design and 4Rx4 organisation let administrators reach large total capacities without populating every available DIMM socket. ECC protection and registered signalling are included for data integrity in mission-critical workloads.

Low-voltage operation and thermal profile

Each module runs at 1.20 V, which is the standard DDR4 voltage, keeping power draw predictable in densely populated chassis. The load-reduced buffer reduces electrical loading on the memory bus, helping the platform maintain stable speeds across many ranks. No specific acoustic or thermal ratings are provided, so cooling should follow the server vendor's general guidelines for high-density LRDIMM configurations.

288-pin DDR4 form factor for compatible platforms

The 288-pin DDR4 SDRAM interface fits motherboards that support PC4-17000 LRDIMMs with 4Rx4 organisation and ECC. Builders must verify that the target platform's memory controller and BIOS recognise this rank configuration and capacity. The low-profile height aids installation in space-constrained 1U or blade systems, but exact clearance requirements depend on the specific chassis and heatsink layout.
