Server Memory for Enterprise Workloads

The A-Tech 64GB DDR5 5600MHz ECC RDIMM is built for server and workstation platforms that require registered error-correcting memory. It targets system integrators and IT professionals upgrading or repairing compatible Samsung M321R8GA0PB0-CWM configurations.

Registered ECC with 2Rx4 Organisation

The module uses a registered ECC RDIMM design with 2Rx4 (EC8) rank structure and Samsung chipset. This specific organisation and buffering scheme is the single specification that determines whether the DIMM will initialise and operate correctly in the target platform.

Steady-State Operation at Standard Voltage

Rated at 1.10V with CL40 latency, the module maintains DDR5 5600 (PC5-44800) throughput under continuous multi-threaded workloads. The registered buffer and on-die ECC sustain data integrity during extended compute cycles without relying on short-burst headroom.

Questions about this item

Will the 5600 MHz speed run at that rate in my server?

The module is rated DDR5 5600 (PC5-44800); actual speed depends on the server's memory controller and any BIOS limits.

What does the ECC RDIMM label mean for my system?

ECC RDIMM indicates registered, error-correcting memory that the motherboard must support; it will not work in unbuffered or non-ECC slots.

Does the 262-pin or 288-pin figure match my motherboard slots?

DDR5 DIMMs use 288 pins; the 262-pin reference in the spec sheet is a typo, so check that your board has DDR5 DIMM slots.
