840758-091 Samsung 1x32GB DDR4 RDIMM ECC RAM

Enterprise DDR4 RDIMM Server Memory Expansion for Virtualization and Database Nodes with the 840758-091

The 840758-091 is a Samsung 32GB DDR4 RDIMM designed to expand memory capacity in enterprise x86 server platforms where predictable latency, uptime, and validated interoperability are required. Deployed in multi-socket hosts, the 840758-091 strengthens the memory footprint for modern CPU generations that depend on balanced channel population to sustain throughput under consolidation-heavy loads.

Built as a 288-pin, 1.2V ECC Registered DIMM, the 840758-091 supports 2666MT/s operation (JEDEC PC4-21300R, CL19) to deliver stable bandwidth for NUMA-aware workloads. Registered buffering improves signal integrity at scale, enabling higher total DIMM counts without sacrificing reliability, while ECC and a 72-bit data path help protect in-flight data in virtualized and database tiers. As servers add PCIe-attached NVMe and accelerators, the 840758-091 helps keep memory capacity aligned with I/O and compute expansion so working sets remain in RAM instead of paging to storage.

Why Choose the 840758-091?

The 840758-091 provides a practical density-to-performance profile for DDR4 RDIMM platforms, enabling incremental upgrades that preserve existing CPU, PCIe, and storage architecture while increasing VM density and in-memory headroom. By using ECC Registered design, the 840758-091 supports enterprise reliability expectations for 24/7 operation and scales cleanly across clustered hosts where consistent configuration reduces validation effort.

Samsung designs server memory for controlled electrical characteristics, long qualification cycles, and predictable behavior under continuous load, supporting modern data centre standards for serviceability, interoperability, and lifecycle management.

Key Applications:

• Virtualization and private cloud hosts
• Enterprise database servers
• In-memory analytics and caching tiers
