512GB DDR5 ECC RDIMM kit for Supermicro workstations

This 512GB kit contains four 128GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for the Supermicro SuperWorkstation SYS-551A-T and compatible X13SWA-TF motherboards that require registered memory.

DDR5 4800 registered ECC limits bandwidth

The modules run at 1.10V with a 4Rx4 organisation and no heat spreader. Registered buffering adds one cycle of command latency, and the fixed CL40 timing caps peak throughput at the rated PC5-38400 data rate for this platform.

Replaces smaller or slower DDR5 RDIMM sets

The jump is worthwhile when the workload needs the full 512GB capacity or when moving from lower-density 4800MHz registered kits that leave DIMM slots unpopulated. It is not for systems that require unbuffered UDIMMs or speeds above 4800MHz.

Highlights

  • Massive 512 GB capacity with four 128 GB modules

  • ECC registered design protects data integrity under load
  • Low 1.10 V operation reduces server power draw
  • Validated for Supermicro SuperWorkstation SYS-551A-T systems

Questions about this item

Which capacity kit should I select for the SuperMicro SYS-551A-T workstation?

The kit contains four 128 GB modules for a total of 512 GB, designed as a matched set for that platform.

What does the DDR5 4800 speed rating deliver when installed in the SuperWorkstation?

The modules run at 4800 MT/s with CL40 latency at 1.1 V, providing the rated PC5-38400 bandwidth in the supported system.

How does the 288-pin RDIMM interface and ECC registration affect usable performance?

The registered ECC design adds a clock cycle for command buffering and enables error correction, which is required for stability in the target SuperMicro motherboard.
