A-Tech 8GB DDR4 2133 ECC RDIMM

This 8GB DDR4 module delivers 2133MHz registered ECC memory for servers and workstations that require error correction and signal buffering. The single-rank 1Rx4 organisation suits platforms qualified for the Samsung M393A1G40BB0-CQB, M393A1G40DB0-CPB or M393A1G40EB1-CPB part numbers. It is not suited for desktop boards that accept only unbuffered non-ECC DIMMs.

8GB capacity with CL15 latency

The 8GB stick handles typical virtualisation hosts, database nodes and multi-user application servers at DDR4-2133 speeds with CL15 timing and 1.20V operation. Workloads that exceed a single module's capacity will require additional DIMM slots and a platform qualified for higher aggregate memory; the module itself does not increase the system's maximum supported memory.

Major-brand Samsung chips and lifetime warranty

Each module uses major-brand Samsung chips tested to the supplier's quality standards before shipment. The lifetime warranty and US-based technical support provide replacement coverage and configuration assistance for the usable life of the part, but they do not alter the electrical specifications or compatibility rules of the host system.

Questions about this item

Will this CL15 1Rx4 DDR4-2133 RDIMM mix reliably with existing CL15 1Rx4 registered ECC modules in the same server?

Yes, matching speed, rank, ECC type and CAS latency gives the best chance of stable operation; always populate identical modules per channel and verify the platform's qualified-vendor list.

How can I confirm the module is running at 2133 MHz with ECC active after installation?

Check the BIOS memory information screen or run dmidecode / lshw on Linux; both will show 2133 MT/s, registered ECC, 1.2 V and single-rank configuration.

Does the package contain only the single 288-pin DDR4 RDIMM, or are any brackets, cables or heat-spreaders included?

Only the 8 GB 288-pin DDR4-2133 ECC RDIMM is supplied; no additional brackets, cables or heat-spreaders are provided.
