System-specific DDR5 ECC RDIMM

This NEMIX RAM module is built for SuperMicro Storage SuperServer SSG-521E and X13SEDW-F platforms. It delivers 16GB of registered DDR5 memory with error-correcting code for data integrity in server workloads. The single 288-pin DIMM operates at 1.10V and targets administrators upgrading compatible SuperMicro systems.

Registered DDR5 4800 with CL40 latency

The module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 and a 1Rx8 organisation. Registered buffering reduces electrical load on the memory controller, allowing stable operation in multi-DIMM server configurations. ECC protection detects and corrects single-bit errors during critical tasks.

16GB capacity for memory-bound services

A single 16GB rank suits virtualisation hosts, database nodes and storage appliances that need ECC reliability without populating every slot. Workloads requiring larger per-socket memory footprints or higher bandwidth than 4800 MT/s will exceed this module's headroom.

Questions about this item

What does the DDR5 4800 CL40 rating deliver in the SSG-521E?

The module operates at 4800 MT/s with CL40 latency, matching the platform's native DDR5 speed for registered ECC workloads.

How does the 288-pin RDIMM interface limit this upgrade?

The registered 288-pin DDR5 form factor requires a compatible RDIMM slot; it cannot be used in UDIMM or SO-DIMM sockets.

What physical clearance does the 1Rx8 module need inside the SSG-521E?

The bare 288-pin PCB has no heat spreader, so it fits standard DIMM spacing without extra height allowance.
