64GB DDR4 LRDIMM for dense server builds
This 64GB DDR4 2400MHz module targets administrators expanding memory capacity in compatible Supermicro platforms. The quad-rank 4Rx4 organisation and load-reduced design allow higher densities per channel than standard registered DIMMs. It suits workloads that benefit from large memory footprints such as virtualisation hosts or in-memory databases. Buyers needing non-ECC or unbuffered memory for desktop boards cannot use this module.
64GB capacity with CL17 latency at 2400MHz
The single module delivers 64GB at PC4-19200 speed with a CAS latency of 17 cycles. Four ranks per channel increase total system capacity but can limit maximum populated DIMM slots on some motherboards. ECC load-reduced operation maintains data integrity while reducing electrical load on the memory controller. Systems requiring faster memory speeds or lower rank counts will not reach their targets with this part.
Supermicro certified with Samsung chipset
Certification as MEM-DR464L-SL01-LR24 confirms compatibility with qualified Supermicro server platforms. The Samsung M386A8K40BM1-CRC components operate at the standard 1.2V DDR4 voltage. No additional software, heatsinks or cables are bundled; the module relies on the host system for cooling and management. Installers must still verify their exact motherboard revision supports quad-rank LRDIMM population rules.

Questions about this item
Will this 2400MHz LRDIMM run at 2400MHz when installed next to older 2400MHz registered DIMMs?
The module operates at DDR4 2400 (PC4-19200) with CL17 latency and 1.20V; mixing LRDIMM with standard registered DIMMs is not supported by server platforms, so all slots must use the same Load Reduced type for the system to run at the rated speed.
How can I confirm the 4Rx4 ECC module is recognised and error-correcting after installation?
Check the BIOS memory map or OS tools such as dmidecode to verify a single 64GB LRDIMM at 2400MHz, 4Rx4 organisation and ECC status enabled; Supermicro-certified modules also pass the vendor's memory self-test on supported boards.
What ships with the MEM-DR464L-SL01-LR24 and what must I supply?
The box contains one 64GB DDR4 2400MHz CL17 4Rx4 ECC LRDIMM (Samsung M386A8K40BM1-CRC, 288-pin); no cables, brackets or additional components are included — only compatible DDR4 LRDIMM slots and a supported server motherboard are required.
