System-Specific DDR5 Server Memory

This NEMIX RAM kit delivers 128GB of DDR5 4800 registered ECC memory in a matched pair of 64GB modules. It is built for the SuperMicro SuperWorkstation SYS-551A-T and X13SWA-TF motherboards. System integrators and IT professionals use it to expand capacity in supported enterprise platforms.

Thermals and Power Profile

Each module operates at a standard 1.10V DDR5 voltage without a heat spreader, relying on chassis airflow for cooling. The registered design adds a clock cycle of buffering to stabilise heavy loads across multiple DIMM slots. Power draw scales with the 4800 MT/s data rate and 2Rx4 organisation during sustained workloads.

Capacity and Rank Configuration

The kit provides two 64GB dual-rank 2Rx4 RDIMMs for a total of 128GB at CL40 latency. Buyers who need a different total capacity, a single-module layout, or non-ECC unbuffered memory for consumer boards cannot use this specific kit.

Questions sur cet article

How do I install the 288-pin DDR5 RDIMM modules in my Supermicro SYS-551A-T, and what step is often missed?

Power down, open the chassis, align the notch on each 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that all 128GB at 4800MT/s are recognised; the step most often missed is seating both clips fully on each 64GB stick.

What maintenance or replacement will this 128GB DDR5 4800 ECC RDIMM kit need over its service life?

No scheduled maintenance is required; keep the server air filters clean so the registered modules stay cool, and if a 64GB stick ever fails the lifetime replacement warranty covers a direct swap.

What limit appears first when this 2Rx4 DDR5 4800 kit runs sustained workloads on the X13SWA-TF platform?

The CL40 latency at 1.10V sets the timing ceiling, so sustained throughput tops out at the rated 38400MB/s before any thermal or voltage headroom is reached.
