128GB DDR5 6400 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5 6400 registered ECC modules built for the Supermicro H13SVW-N motherboard. Each module runs at 1.10V with CL52 timing and a 2Rx8 organization. The 288-pin RDIMM form factor matches the board's memory slots exactly.

Registered ECC with verified fitment

Registered buffering reduces electrical load on the memory controller so all four slots can be populated at full rated speed. On-board ECC detects and corrects single-bit errors to prevent silent data corruption and unexpected reboots. The kit is validated for the H13SVW-N population rules and pinout.

Suited for full-population server builds

Ideal for administrators upgrading a Supermicro H13SVW-N to its maximum supported capacity with matched modules. Not suitable for systems that require unbuffered UDIMMs, SODIMM form factors, non-ECC memory, or a different DDR generation. Builders needing a different capacity or rank configuration should consult the motherboard manual first.

Highlights

  • 128 GB total capacity with four 32 GB modules for full server population
  • DDR5 6400 speed rated at CL52 latency for rated throughput
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 10 V operation matches the motherboard's memory-controller specification exactly
  • Verified 288-pin RDIMM fitment for the Supermicro H13SVW-N motherboard

Questions about this item

Will the 2Rx8 registered ECC modules need any firmware updates or reconfiguration after installation in the Supermicro H13SVW-N?

The kit is an exact-match upgrade spec-matched to the board's memory-population rules, so it is recognised at full 128GB capacity and rated DDR5 6400 speed without extra configuration.

What limit appears first when all four 32 GB RDIMMs run at DDR5 6400 CL52 continuously?

The memory controller manages every slot fully populated at full capacity through the registered architecture, so sustained throughput is bound by the DDR5 6400 data rate and CL52 latency of the modules themselves.

How much heat and power does the 1.1 V DDR5 6400 kit produce during all-day operation without heat spreaders?

Operating at 1.1 V with no heat spreaders, the registered ECC RDIMMs draw minimal power and generate low thermal output, while the buffered design offloads the memory controller for efficient all-day running.
