512GB DDR5 ECC RDIMM Kit

This 512GB kit contains four 128GB DDR5 4800 registered DIMMs built for Supermicro SuperWorkstation SYS-751A-I and X13DAI-T platforms. ECC and registered operation protect data integrity in mission-critical server and workstation workloads. The modules run at 1.1V with CL40 latency. IT professionals who need validated compatibility for these specific Supermicro systems are the target buyers.

288-Pin Registered 4Rx4 Modules

Each stick uses a 288-pin DDR5 RDIMM form factor with 4Rx4 organisation and no heat spreader. Major OEM Samsung, Micron or Hynix chips are used depending on supply. Registered buffering reduces electrical load on the memory controller, allowing all four slots to be populated reliably. Builders who require unbuffered UDIMMs or desktop-style heat spreaders should look elsewhere.

Upgrade from Smaller DDR5 Kits

The kit replaces lower-capacity DDR5 registered memory to reach 512GB in four slots. The jump is worth it when virtualisation, large datasets or multi-tenant workloads exceed the current memory ceiling. Buyers who need more than four DIMM slots or higher speeds than 4800 MT/s cannot use this product.

Questions about this item

What speed does the DDR5 4800 PC5-38400 interface run at in practice?

The modules operate at 4800 MT/s with a PC5-38400 bandwidth rating, delivering 38400 MB/s theoretical peak throughput.

What physical slots and clearance do the 288-pin RDIMMs need?

Each 128 GB module uses a standard 288-pin DDR5 RDIMM form factor; four DIMM slots are required and no heat spreader is fitted, so low-profile coolers clear easily.

How are the 4Rx4 registered ECC modules installed and what step is often missed?

Power down, open the chassis, align the key notch, press each RDIMM firmly until both retention clips click, then enable ECC in the BIOS — skipping the BIOS step leaves error correction inactive.
