512GB DDR5-6400 RDIMM Kit

This 512GB kit contains eight 64GB DDR5-6400 registered ECC RDIMMs built for the Supermicro H13DSG-OM motherboard. Each module runs at 1.10V with CL52 latency and a 2Rx4 organization. The 288-pin form factor matches the board's memory slots exactly.

Supermicro H13DSG-OM Memory Upgrade

This kit suits administrators who need the full 512GB capacity validated for that specific motherboard. It is not for systems that require unbuffered UDIMMs, SODIMM modules, or a different voltage and timing profile. Builders using other server platforms should verify their qualified vendor list before ordering.

Registered ECC 2Rx4 Architecture

Registered buffering offloads the memory controller so all eight slots operate at the rated 6400 MT/s, while on-die ECC corrects single-bit errors in flight. The 2Rx4 rank structure is what the H13DSG-OM memory controller expects for full-population stability.

Questions about this item

Will the 6400 MT/s rating actually run at that speed in my H13DSG-OM?

The kit is spec-matched to the Supermicro H13DSG-OM memory controller, so the 8 x 64 GB modules are recognised at full capacity and operate at DDR5-6400 with CL52 timing.

What does the PC5-51200 label tell me about real bandwidth?

PC5-51200 is the peak transfer rate for DDR5-6400; the registered buffer lets all eight slots stay populated at that rate without down-clocking.

Do the 288-pin RDIMMs fit straight into the H13DSG-OM DIMM slots?

Yes — the 288-pin registered form factor is exactly what the H13DSG-OM requires; no UDIMM or SODIMM will work in its place.
