Samsung 8GB DDR4-2133 ECC Registered DIMM M393A1G40EB1-CPB | Server RAM

Protect uptime in server environments where memory integrity matters. This Samsung 8GB DDR4 module runs at 2,133 MHz with ECC registered signaling, giving compatible systems the correction and electrical isolation needed for reliable operation in dense, always-on deployments. The CL15 timing profile supports consistent response behavior, while the single-rank x4 architecture helps balance capacity and platform compatibility. For infrastructure teams, this is the kind of memory you specify when the cost of instability is higher than the cost of the module itself. It fits workloads that need steady performance more than headline bandwidth: virtualization hosts, small database nodes, application servers, and edge systems that must stay predictable through long duty cycles. The 1.2 V design also aligns with DDR4 efficiency expectations, helping keep thermal load and power draw in check. Choose this module when you need qualified server-grade memory rather than consumer DIMMs. ECC registered support, conservative timing, and Samsung manufacturing quality make it a practical fit for procurement standards that prioritize uptime, compatibility, and lifecycle consistency.
