M386AAG40MMB-CVF Samsung 1x128GB DDR4 LRDIMM ECC RAM

High-Capacity DDR4 LRDIMM Server Memory for Scale-Up Platforms with the M386AAG40MMB-CVF

The M386AAG40MMB-CVF is a Samsung 128GB DDR4-2933 ECC Registered LRDIMM engineered to increase per-socket memory capacity in enterprise x86 server platforms without destabilizing timing margins. By using a load-reduced architecture with registered buffering, the M386AAG40MMB-CVF helps maintain signal integrity as DIMM populations grow, supporting dense memory footprints for modern multi-core CPU generations where memory bandwidth and capacity directly influence consolidation ratios.

In virtualized and scale-up configurations, the M386AAG40MMB-CVF enables larger VM memory reservations and reduces contention for NUMA-local memory. Its 2933 MT/s data rate aligns with common DDR4 memory controllers to sustain predictable throughput for in-memory databases and analytics. While PCIe generation and storage tiers define I/O performance, the M386AAG40MMB-CVF targets the memory layer that governs cache-miss penalties, page locality, and sustained query execution under high concurrency.

Why Choose the M386AAG40MMB-CVF?

The M386AAG40MMB-CVF is selected when architects need maximum DDR4 capacity per slot with enterprise-grade error correction and the scalability characteristics of LRDIMM buffering. This module supports higher DIMM density per server, improving performance-per-rack unit for consolidation projects while preserving reliability through ECC and registered design practices that are standard in mission-critical deployments.

Samsung designs server memory with a focus on qualification discipline, consistent electrical characteristics, and long-life supply alignment for data centre operations. The module profile and 1.2V DDR4 operating point support efficient thermals and integration into established platform validation matrices.

Key Applications:

• Server virtualization and consolidation
• In-memory databases
• Real-time analytics
• Scale-up enterprise applications
