Exact-Match Server Upgrade

This 512GB kit contains four 128GB DDR5 RDIMMs built for the Supermicro H13SSL-NT motherboard. Each module runs at 6400 MT/s with CL52 latency at 1.1V. Registered ECC architecture ensures the memory controller recognises the full population at rated speed.

Registered ECC Changes Daily Operation

Registered buffering offloads the memory controller so all four slots operate at full capacity. On-die ECC detects and corrects single-bit errors before they reach the operating system, preventing silent data corruption and unplanned reboots in production workloads.

288-Pin RDIMM Form Factor Implications

The 288-pin Registered DIMM form factor matches the board's physical and electrical requirements — no UDIMM or SODIMM alternatives fit. Major OEM Samsung, Micron or Hynix chips underpin long-term stability. Verify your manual for supported population order before installation.

Questions about this item

Will the 128GB modules or their ECC function need scheduled replacement?

The modules have no moving parts and the ECC function is built into the DDR5 chips, so no scheduled replacement is required.

What limit appears first when the 512GB kit runs at 6400 MT/s continuously?

The memory controller on the Supermicro H13SSL-NT motherboard sets the maximum sustained throughput, so the platform limit is reached before the modules themselves throttle.

How much heat and power does the 1.1V registered kit produce under all-day load?

Each 128GB RDIMM operates at 1.1V without a heat spreader, so total power draw and thermal output stay low even with all four slots populated.
