SAMSUNG M393A1G43DB0-CPB 8GB DDR4 2133 RDIMM
The Samsung M393A1G43DB0-CPB is an 8GB DDR4-2133 registered DIMM (RDIMM) built for servers, data centers, workstations, and virtualization platforms. It suits buyers populating or extending legacy DDR4 platforms — virtualization hosts, cache tiers, and general-purpose server workloads — where ECC-registered memory is mandatory. As an entry-density DDR4 RDIMM, it is a practical fit for rounding out memory channels on existing servers rather than new high-capacity builds; verify platform support before ordering.

Good to know
- RDIMMs cannot be mixed with desktop UDIMMs or with DDR5 modules — populate only in server platforms that explicitly support DDR4 registered memory, and follow your vendor’s channel population guide for optimal performance.
- Within Samsung’s DDR4 RDIMM family, this 8GB single-rank module represents the entry capacity tier; single-rank modules often allow more DIMMs per channel than dual-rank equivalents, though maximum supported speed may be downgraded by the platform depending on population.
- When scaling capacity across a virtualization host or cache tier, order modules of identical part number, rank, and speed grade to avoid mixed-population instability — request current stock and revision details from our Huaqiangbei export desk before bulk purchase.
