Server memory kit for Supermicro workstations

This 2 TB kit contains sixteen 128 GB DDR5 4800 registered ECC modules built for Supermicro SuperWorkstation SYS-551A-T and X13SWA-TF systems. It targets IT teams who need maximum capacity in a validated configuration. Each module runs at 1.1 V with CL40 latency.

Registered ECC with 4Rx4 organisation

The modules use a 4Rx4 layout and registered buffering, which is the single specification that determines compatibility with the target Supermicro platforms. Speed is rated at DDR5 4800 (PC5-38400) and the kit ships as a matched set of sixteen pieces.

Suited for memory-bound server workloads

Buyers who need the highest supported density for virtualisation, in-memory databases or scientific computing will benefit. Builders who require consumer DIMM form factors, non-ECC operation or lower-capacity kits should look at something else.

Questions about this item

Will 4800 MT/s DDR5 actually run at 4800 MT/s in a Supermicro SYS-551A-T workstation?

The kit is rated DDR5 4800 (PC5-38400). Installed in a compatible Supermicro SYS-551A-T it will operate at that speed provided the CPU and BIOS support 4800 MT/s.

Does the registered ECC design require a motherboard that supports registered DIMMs and ECC?

Yes. These are 288-pin DDR5 RDIMMs with on-die ECC and a register. The platform must accept registered ECC modules; consumer boards that only take unbuffered non-ECC DIMMs will not work.

What physical clearance is needed for 16 modules of this kit in the SYS-551A-T?

Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader. The chassis and CPU cooler must leave enough vertical space for all 16 slots to be populated side by side.
