  • 128 GB capacity lets you fully populate the Supermicro H13SSW at rated speed
  • Registered ECC design offloads the memory controller and corrects single-bit errors on the fly
  • DDR5 5600 (PC5-44800) CL46 timing matches the board's memory controller expectations exactly
  • 1 V operation at 2Rx4 rank keeps power draw low while running every slot at full capacity
  • 288-pin RDIMM form factor fits the H13SSW DIMM slots — not a UDIMM or SODIMM

Exact-match DDR5-5600 RDIMM for Supermicro H13SSW

This 128GB DDR5 module delivers 5600 MT/s (PC5-44800) at 1.1V with CL46 latency. The 2Rx4 registered ECC design matches the memory-controller requirements of the Supermicro H13SSW motherboard so the system recognises the full capacity and runs at rated speed.

Registered ECC architecture with OEM chips

The buffered RDIMM layout offloads the memory controller, allowing every populated slot to operate at full capacity. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots. Samsung, Micron or Hynix DRAM ensures enterprise-grade stability.

DDR5 RDIMM form-factor and population rules

The 288-pin registered DIMM fits only boards that support DDR5 RDIMMs — it will not work in UDIMM or SODIMM slots. Maximum capacity and supported population order depend on the specific motherboard revision and BIOS, so consult the Supermicro H13SSW manual before installation.

Questions about this item

Will the 1.10V DDR5 RDIMM require any maintenance or replacement down the line?

The module has no moving parts or heat spreader, so no scheduled maintenance is needed; ECC corrects single-bit errors on the fly and the lifetime replacement warranty covers any failure.

What limit appears first when the 128GB 2Rx4 kit runs at 5600MHz continuously?

The registered buffer and ECC let every slot stay fully populated at rated speed, so the platform's maximum supported capacity per slot is the first ceiling you will hit.

How much heat and noise does the CL46 1.1V registered DDR5 produce under all-day load?

Operating at 1.1V without a heat spreader keeps thermal output low, and because memory is silent the only noise comes from the server fans moving air across the 288-pin RDIMM.
