System-Specific DDR5 RDIMM Kit

This 128 GB kit contains eight 16 GB DDR5 4800 CL40 ECC registered DIMMs built for the Supermicro SuperWorkstation SYS-551A-T. It targets IT professionals who need validated, server-grade memory for mission-critical workloads.

Registered ECC with 1Rx8 Organisation

The modules run at 1.10 V, use a 288-pin DDR5 interface and present a single-rank 1Rx8 layout with CL40 latency. Registered buffering and on-die ECC protect data integrity under sustained load, making this the decisive spec for compatibility.

Straightforward DIMM Installation

Installation follows standard server-board procedure: power down, open the chassis, seat each module until the ejectors click, then verify population order in the manual. The most common issue is mixing registered and unbuffered DIMMs, which prevents the system from posting.

Questions about this item

How does the DDR5 4800 speed translate once the 8 modules are installed in the SuperWorkstation SYS-551A-T?

The eight 16 GB modules run at 4800 MT/s with CL40 latency, giving the workstation 128 GB of registered ECC capacity at the rated data rate.

What does the PC5-38400 rating cap in everyday use?

PC5-38400 is the peak transfer specification for DDR5 4800; the registered buffer and ECC overhead set the practical throughput ceiling at that same 4800 MT/s rate.

Will the 288-pin RDIMMs fit the SuperMicro X13SWA-TF motherboard without extra hardware?

Yes, the 288-pin DDR5 RDIMM form factor matches the X13SWA-TF memory slots exactly; no adapters or special brackets are required.
