About the Samsung 128GB DDR4 LRDIMM M386AAG40DM3-CRC
Samsung DDR4-2400 128GB LRDIMM delivers enterprise-class memory performance at 2400 MT/s in a quad-rank, load-reduced configuration—purpose-built for high-density server deployments.
The Samsung M386AAG40DM3-CRC is a 128GB DDR4 LRDIMM engineered for mission-critical infrastructure requiring maximum memory capacity with minimal electrical load on server motherboards. This module features Samsung's proven DDR4 technology paired with Load-Reduced DIMM architecture, making it ideal for data center architects and IT infrastructure teams scaling large-footprint environments. The quad-rank (4Rx4) design enables data centers to populate server slots with maximum capacity while the LRDIMM buffer reduces strain on memory controllers—critical for multi-socket systems. Running at DDR4-2400 speeds with 288-pin connectivity and full ECC protection, this Samsung module meets stringent reliability standards for 24/7 operational demands. Voltage regulation at 1.2V ensures efficiency and thermal stability across the operating temperature range of 0°C to 85°C.
Storage architects and IT procurement teams benefit from the M386AAG40DM3-CRC's RoHS-compliant design, CAS Latency 17 timing, and 72-bit error correction—eliminating silent data corruption in virtualized and high-availability workloads. Samsung's enterprise memory carries proven track records in hyperscale and financial services deployments throughout the Middle East region.
