Server DDR5 ECC RDIMM Upgrade

This A-Tech module delivers 16GB of DDR5-5600 registered ECC memory for server and workstation platforms. It operates at the standard 1.1V voltage with a CAS latency of 40 and uses a 1Rx8 organisation built on major-brand DRAM ICs. The 288-pin RDIMM form factor is designed for multi-slot channels in enterprise environments.

Platform Compatibility Checks

Verify that your motherboard supports DDR5 registered DIMMs and accepts 1Rx8 modules at 5600 MT/s. Confirm the memory controller can address ECC RDIMM topology and that the BIOS is current enough for DDR5-5600 operation. Consult the system manual for correct slot population rules and maximum per-channel capacity before ordering.

Ideal For ECC Workstations And Servers

Suits administrators expanding memory in DDR5-ready servers or workstations that require registered ECC modules. Not suited for consumer desktop boards that only accept unbuffered non-ECC UDIMMs. Builders needing heat spreaders or higher-density ranks should evaluate other configurations.

Questions about this item

Does the 16GB DDR5 5600 ECC RDIMM come as a single stick or a kit, and is a heat spreader included?

The module is sold as a single 16GB stick (1Rx8) without a heat spreader; additional modules must be purchased separately to reach your desired total capacity.

Should I choose this 1Rx8 16GB module or look for a 2Rx8 alternative for my server?

This 1Rx8 design places all 16GB on one rank, which typically allows higher memory speeds and leaves more DIMM slots free for future expansion compared to dual-rank options.

What does the 5600 MT/s speed with CL40 latency mean for actual server workloads?

The DDR5 5600 rating delivers 44,800 MB/s peak bandwidth per module; CL40 at 1.1V gives low-latency access for database and virtualization tasks when the platform runs at the rated speed.
