16GB DDR5 5600 ECC RDIMM Server Memory

This A-Tech module delivers 16GB of DDR5 5600 registered ECC memory for server and workstation platforms. It operates at the standard 1.10V and uses a 288-pin DIMM form factor with Samsung chipset. The single-rank 1Rx8 organisation and CL40 latency suit enterprise workloads requiring data integrity.

Suited for systems that support registered ECC

Buyers whose motherboards accept only unbuffered non-ECC DIMMs cannot use this module. It is also not for platforms that require a different DDR generation or a 262-pin form factor.

Registered ECC with 1Rx8 organisation

The registered buffer and on-die ECC provide the error correction and signal integrity needed for multi-DIMM server channels. Systems that lack RDIMM support will not POST with this module installed.

Questions about this item

Does my motherboard need a 288-pin DDR5 DIMM slot for this module?

Yes, the module is a 288-pin DDR5 DIMM and requires a matching DDR5 DIMM socket.

Can I add this 1Rx8 ECC RDIMM alongside existing registered DDR5 modules in my server?

Yes, it is a registered ECC RDIMM with 1Rx8 organisation and will operate with other registered DDR5 modules when the platform supports mixed ranks.

How can I confirm the module is running at 5600 MT/s with CL40 after installation?

Check the memory speed and latency in BIOS or a system utility such as CPU-Z; they should report 5600 MT/s and CL40 at 1.1 V.
