  • 1TB capacity with eight 128GB DDR5 modules for maximum server density
  • DDR5-6400 PC5-51200 speed at CL52 latency for rated throughput
  • 2Rx4 registered ECC architecture offloads controller and corrects single-bit errors
  • 1V operation matches platform spec for stable full-population performance

Exact-match server kit

This 1TB kit contains eight 128GB DDR5 RDIMM modules rated at 6400MHz with CL52 latency and 1.1V operation. It is built for the Supermicro H13DSG-OM motherboard and delivers registered ECC memory with a 2Rx4 rank configuration.

Installation notes

Modules use the standard 288-pin RDIMM form factor and seat like any server DIMM. The board requires registered memory, so UDIMM or SODIMM parts will not function; consult the manual for the approved population order before filling all eight slots.

Critical specification

Registered ECC architecture with 2Rx4 organisation is the single attribute that determines compatibility. Without it the memory controller cannot address the full 1TB capacity at the rated 6400MHz speed.

Questions about this item

How do I confirm the kit runs at DDR5-6400 CL52 after installation?

Enter the BIOS and verify the memory frequency shows 6400 MT/s with timings at 52-52-52; the registered ECC design ensures all eight slots operate at rated speed when populated per the motherboard manual.

What exactly ships in the 1 TB kit and is anything else required?

The box contains eight 128 GB DDR5 288-pin RDIMMs pre-tested as a matched set; no extra cables, brackets or software are needed — just follow the Supermicro H13DSG-OM population guide.

Why choose the 8 × 128 GB 2Rx4 configuration instead of a different capacity?

This 2Rx4 registered ECC layout at 1.1 V is the exact rank and voltage the H13DSG-OM memory controller expects for full 1 TB operation across all channels.
