Why DDR4 RAM is so expensive?

DDR4 RAM is expensive because most manufacturers have shifted production to DDR5, reducing DDR4 supply, while securing limited DDR4 allocations mainly for servers and enterprise systems instead of desktop PCs; combined with ongoing demand, past production cuts, and distributor markups, this keeps prices high.

What is the speed and CAS latency of the Samsung 64GB DDR4 SDRAM memory module?

The speed of the Samsung 64GB DDR4 SDRAM memory module is DDR4 2666 (PC4 21300) and it has a CAS latency of CL19.

What is the capacity of the Samsung M386A8K40BM2-CTD memory module?

The capacity of the Samsung M386A8K40BM2-CTD memory module is 64GB.

Samsung LR-DIMM server memory

The Load Reduce DIMM (LR-DIMM) uses a buffer memory chip, instead of register found on RDIMM. This allows more memory Ranks to be populated on a single module, resulting higher capacity. This type of server memory is beneficial to data intensive applications in data centers, Cloud computing and high-performance computing.

The Samsung server memory module is manufactured with premium quality components, tested to rigorous standards, and validated in a wide range of systems. This guarantees the best possible stability, reliability and compatibility. Maximize expensive workstation and server investments by inexpensively installing more memory.

Please note: Not all systems accept LR-DIMM. Please check whether the LR-DIMM is supported before purchase. LR-DIMM cannot be mixed with other memory types including RDIMM, ECC UDIMM and UDIMM.

Proven DRAM Module Solution in the Global Market Samsung's memory modules are designed for a wide range of applications to deliver the best performance with low power requirements.
