Exact-Match DDR5 Server Upgrade

This NEMIX RAM module provides 64 GB of DDR5-4800 ECC Registered memory in a 288-pin RDIMM form factor. It operates at 1.1 V with CL40 latency and a 2Rx4 rank configuration. The specification matches the Supermicro H13SSF motherboard requirements so the system recognises the full capacity at rated speed.

Built for Populated Enterprise Slots

Suited for administrators expanding a Supermicro H13SSF platform that demands registered ECC DIMMs for full-slot stability and error correction. Not intended for workstations or desktops that accept only unbuffered UDIMMs, nor for laptops requiring SODIMM modules.

Handles Full-Population Registered Loads

The registered architecture offloads the memory controller, allowing every supported slot to run at 64 GB with ECC protection against single-bit errors. Capacity ends at 64 GB per module; systems needing larger per-DIMM densities or non-registered memory must choose a different specification.

Questions about this item

What motherboard must I already have for this NEMIX RAM DDR5 4800MHz CL40 2Rx4 ECC RDIMM to work?

This module is validated for the Supermicro H13SSF motherboard. It uses the 288-pin Registered RDIMM form factor and 1.1V operation that board requires.

Will this 64GB DDR5 4800MHz ECC RDIMM run alongside any existing DDR5 RDIMMs I keep in the H13SSF?

Mixing ranks or speeds can prevent full-speed operation. For stable 4800MHz CL40 performance across all slots, populate every channel with identical 2Rx4 registered ECC modules.

How do I confirm the 64GB DDR5 4800MHz CL40 kit is running at its rated speed after install?

Enter the BIOS or use a hardware inventory tool. Verify the memory reports 4800 MT/s, CL40 timings, 1.1V, ECC active, and the full 64GB capacity per module.
