Samsung 32GB DDR3 4Rx4 PC3-14900L Memory Module

The Samsung M386B4G70BM0-CMA is a 32GB DDR3 Load Reduced DIMM designed for servers that need more memory headroom without sacrificing stability. It delivers additional capacity for virtual machines, large databases, and other memory-hungry workloads while protecting signal quality through onboard buffering and a register that manages command and control traffic.

Running at 1866 Mbps, the module moves data quickly enough to keep multi-core processors fed during peak demand. The 4Rx4 rank structure distributes the 32 gigabytes across four ranks of x4 devices, a layout that helps the memory controller access data efficiently even in high-load situations.

Dual-voltage support allows operation at either 1.5 V or 1.35 V. This flexibility is useful when matching mixed populations of DIMMs or when you are fine-tuning power budgets in an energy-conscious data center. The standard 240-pin form factor means installation is straightforward in any compatible DDR3 server slot.

Because the module places less electrical load on the memory bus than conventional RDIMMs, it enables configurations with up to three DIMMs per channel. That makes it a practical choice for administrators who need to populate every slot in a dual- or quad-socket board to reach higher overall capacities.

Whether you are building out a virtualization host, refreshing a database node, or extending the life of an existing rack server, this Samsung LRDIMM brings the capacity and reliability needed for around-the-clock enterprise workloads.
