128GB DDR5 4800 ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR5 4800 registered ECC RDIMMs. It is built for the Supermicro H13SSW motherboard and matches the board's 288-pin RDIMM requirement. The modules run at 1.1V with CL40 timing and 1Rx8 organisation.

Ideal for Supermicro H13SSW Servers

Suits administrators upgrading a Supermicro H13SSW to its full 128GB registered ECC capacity. Not for systems that need unbuffered UDIMMs, SODIMMs or non-ECC memory. Builders requiring a different capacity or speed should verify their motherboard manual first.

DDR5 4800 Registered ECC with 1Rx8 Rank

The single specification that decides fitment is the 1Rx8 registered ECC configuration at DDR5 4800. The H13SSW memory controller expects this exact rank, voltage and timing combination for full-speed operation across all eight slots.

Questions about this item

What motherboard must I already have to install this 128GB DDR5 4800 ECC RDIMM kit?

The kit is validated for the Supermicro H13SSW motherboard, which accepts 288-pin registered DDR5 DIMMs at 1.1V.

Will these 1Rx8 registered modules work if I keep older DDR5 DIMMs in the remaining slots?

Mixing ranks or speeds is not recommended; the board's population rules require identical registered ECC modules in each channel for full 128GB operation.

How do I confirm the kit runs at 4800MT/s CL40 after installation?

Check the BIOS memory information screen — it should report DDR5-4800, PC5-38400, CAS latency 40, and all eight 16GB modules detected.
