  • 768 GB total capacity from six 128 GB modules for memory-intensive server workloads
  • DDR5 5600 speed with CL46 latency delivers rated performance on supported platforms
  • Registered ECC architecture corrects single-bit errors and offloads the memory controller
  • 10 V operation matches the motherboard's voltage requirement for stable operation
  • Verified compatibility with the Supermicro H13SSL-NT motherboard ensures correct fitment

Exact-Match Server Memory Kit

This NEMIX RAM kit delivers 768GB across six 128GB DDR5 RDIMM modules rated at 5600 MT/s with CL46 timings and 1.1V operation. Each module uses a 2Rx4 registered ECC design on a 288-pin form factor built with major OEM DRAM chips. The kit is validated for the Supermicro H13SSL-NT motherboard to ensure full-capacity recognition and rated-speed operation.

Suited For Dense Virtualisation Hosts

Ideal for administrators populating every DIMM slot on a compatible Supermicro platform where registered ECC memory is required for stability and error correction. Not suited for desktop boards that accept only unbuffered UDIMMs, for systems limited to lower maximum capacities per slot, or for workloads that demand lower latency timings than CL46.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller so all six slots remain stable at full population during continuous operation. ECC corrects single-bit errors in real time to prevent silent data corruption during long-running compute tasks. The 1.1V DDR5 baseline keeps power draw consistent under sustained throughput.

Questions about this item

What motherboard must I already have for this 6x128GB DDR5 5600 RDIMM kit to be recognised at full capacity?

The kit is validated for the Supermicro H13SSL-NT motherboard; its 288-pin registered DIMM form factor and 2Rx4 organisation match that board's memory-population rules exactly.

Will the registered ECC design of these modules work with older unbuffered UDIMM slots I might still be using?

No — the modules are 288-pin RDIMMs with registered architecture and ECC; they require a motherboard that supports registered DDR5 memory and will not function in UDIMM or SODIMM slots.

How can I confirm the kit is running at its rated 5600 MT/s CL46 after installation?

Enter the system BIOS or use a hardware-information utility; the memory speed should show 5600 MT/s (PC5-44800) with CAS latency 46 and voltage at 1.10 V across all six modules.
