NEMIX RAM DDR5 6400 256GB Kit

This 256GB kit contains eight 32GB DDR5 6400 RDIMMs rated CL52 at 1.1V. Registered ECC architecture with 2Rx8 organisation is built for the Supermicro H13SST-GC motherboard and identical platforms that require 288-pin registered modules.

Suited For Supermicro H13SST-GC Servers

Ideal for administrators populating every slot on a Supermicro H13SST-GC board with validated registered ECC memory. Not for systems that accept only unbuffered UDIMMs or SODIMMs, nor for builds needing lower voltage or different latency targets.

Registered ECC 2Rx8 DDR5 6400 Specification

The 2Rx8 registered ECC design at DDR5 6400 CL52 1.1V is the decisive factor; the memory controller expects this exact rank, voltage and timing for full-capacity recognition and rated-speed operation.

Questions about this item

My Supermicro H13SST-GC board has 8 DDR5 slots. Will this 8-module kit fill every slot at once?

Yes. The kit provides eight 32 GB DDR5-6400 RDIMMs for a total of 256 GB, matching the board's eight 288-pin slots so you can populate all channels in one step.

Will the registered ECC design work with the memory controller on my Supermicro H13SST-GC?

The modules are 2Rx8 registered ECC RDIMMs at 1.1 V CL52, the exact rank, voltage and timing the H13SST-GC memory controller expects for full-capacity operation.

After installation, how can I confirm the kit is running at DDR5-6400 with ECC active?

Check the BIOS memory information or run a tool such as dmidecode; it should show 6400 MT/s, CL52, 1.1 V, registered ECC and 256 GB total across all eight DIMMs.
