Target system and kit composition

This NEMIX RAM kit supplies 96GB across six 16GB DDR5 RDIMM modules. It is built for the Supermicro SuperWorkstation SYS-551A-T and X13SWA-TF platforms that require registered ECC memory.

Registered ECC with CL40 timing

Each module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.10V. The 1Rx8 registered design provides the error-correction and signal buffering those workstations demand for stable operation.

Six-module population without heat spreaders

The bare 288-pin RDIMMs insert directly into the board’s DDR5 slots; no spreader clearance issues arise. Installers must populate all six channels in the order the manual specifies, otherwise the system will not train the memory correctly.

Questions about this item

How does the 4800 MT/s speed behave once the modules are installed in a Supermicro SuperWorkstation SYS-551A-T?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, delivering the rated throughput on the supported platform.

What does the 288-pin RDIMM form factor limit in practice?

The registered 288-pin DDR5 RDIMM design requires a server or workstation motherboard with matching RDIMM slots; it will not fit consumer UDIMM sockets.

What physical clearance is needed for the six 16 GB sticks?

Six standard-height 288-pin modules occupy six adjacent DIMM slots; ensure the chassis and CPU cooler leave enough vertical space for full insertion.
