Samsung 16GB DDR3-1866 LP ECC REG Server Memory Module

The Samsung M393B2G70EB0-CMA is a 16 GB server memory module that follows the DDR3 specification at 1866 MT/s. Designed as a Registered DIMM with Error Correcting Code, it brings extra signal stability and automatic bit-level corrections to keep demanding workloads running without interruption.

Inside the module, a built-in register reshapes clock, command, and control signals before they reach the DRAM chips. This extra stage reduces electrical noise and helps maintain signal integrity when multiple DIMMs share the same memory channel. An additional 8-bit parity lane lets the system detect and repair single-bit errors on the fly, which is essential for database servers, virtualized hosts, and any application where corrupted data cannot be tolerated.

The ability to operate at either 1.5 V or 1.35 V gives datacenter administrators flexibility when balancing performance and power budgets. In platforms that support the lower voltage, the module draws less current, cutting heat output and overall rack power consumption. This makes it a practical upgrade for blade enclosures, dense rack servers, or edge systems that must stay within tight thermal envelopes.

A dual-rank, 2 R × 4 layout provides the capacity needed for memory intensive tasks while still fitting into a standard 240-pin DDR3 slot. When installed in a two-DIMMs-per-channel configuration, the module makes efficient use of available memory channels and can help reach the maximum supported capacity of many enterprise motherboards.

System integrators and IT teams that manage virtualization clusters, in-memory analytics engines, or high-traffic web servers will find this module especially useful. It delivers consistent throughput, safeguards data integrity, and offers the power flexibility that modern datacenters increasingly demand.
