  • 64 GB total capacity from a 2 x 32 GB kit for maximum server memory density
  • DDR5 4800 speed with CL40 latency delivers rated bandwidth without downclocking
  • Registered ECC architecture corrects single-bit errors and supports full-slot population
  • 1 V operation matches the Supermicro H13SSW memory controller specification exactly
  • 288-pin RDIMM form factor fits the board's required DIMM slots precisely

H13SSW DDR5 ECC RDIMM upgrade

This 64GB kit contains two 32GB DDR5 4800 modules built to the exact 2Rx8 registered ECC specification the Supermicro H13SSW motherboard requires. Each DIMM runs at 1.1V with CL40 timing and uses the 288-pin RDIMM form factor so the board recognises the full capacity at rated speed without manual configuration.

Server builders needing registered ECC stability

Administrators who need registered ECC memory for data-integrity workloads on the H13SSW platform will find this kit matches the board's population rules and voltage requirements. Builders using consumer UDIMMs or SODIMMs, or systems that require unbuffered non-ECC modules, cannot use this registered DDR5 RDIMM kit.

2Rx8 registered ECC at 1.1V

The dual-rank 2Rx8 organisation combined with registered buffering and on-die ECC is the single specification that determines whether the memory controller can address the full 64GB at DDR5 4800 without errors. If your server manual calls for a different rank structure, voltage or unbuffered DIMMs, this kit will not be compatible.

Questions about this item

What motherboard do I need so this 288-pin DDR5 RDIMM kit is recognised at full 64GB capacity?

The kit is validated for the Supermicro H13SSW motherboard; its memory controller expects DDR5-4800, 1.1V, CL40, 2Rx8 registered ECC modules in the 288-pin RDIMM form factor.

Will this registered ECC DDR5 kit operate alongside any RDIMMs already installed in my H13SSW?

The H13SSW requires identical rank, voltage and timing per channel; mixing different RDIMMs can prevent full-speed operation, so populate slots using matched kits only.

How do I confirm the system is running the memory at DDR5-4800 CL40 with ECC active?

Check the BIOS memory information screen or run a tool such as dmidecode — it should show 4800 MT/s, CL40, 1.1V, registered ECC and the full 64GB capacity.
