Supermicro H14SSL-N DDR5 RDIMM kit

This NEMIX RAM kit delivers 64 GB of DDR5 ECC Registered memory in a matched pair of 32 GB modules. It operates at 4800 MT/s with CL40 latency at 1.1 V using the 288-pin RDIMM form factor required by the Supermicro H14SSL-N motherboard. The 2Rx8 organisation and registered design satisfy the board's population rules for full-capacity operation.

Suited for servers needing registered ECC memory

The registered architecture and on-die ECC make this kit appropriate for workloads that demand error correction and signal integrity across fully populated slots. It is not intended for platforms that accept only unbuffered UDIMMs or SODIMMs, nor for systems limited to lower DDR5 speeds or different pin counts. Buyers who need higher capacities per module or lower latencies should verify their board's qualified-vendor list first.

Fits 288-pin RDIMM slots on the H14SSL-N

Each module slots directly into the motherboard's DDR5 RDIMM sockets without adapters or converters. The 1.1 V operating voltage matches the platform's native rail, leaving headroom for the CPU memory controller when all channels are filled. Confirm the manual's population order before installation to ensure the controller initialises every rank at the rated 4800 MT/s.

Questions about this item

Do I need a motherboard with 288-pin DDR5 RDIMM slots to install this 64GB kit?

Yes, the kit uses 288-pin DDR5 RDIMM modules that require a board designed for registered ECC memory, such as the Supermicro H14SSL-N.

Will the registered ECC design of these DIMMs let me fully populate the H14SSL-N without signal-loading issues?

The registered architecture buffers address and command signals, allowing every slot to run at the rated 4800 MHz speed even when all channels are filled.

How can I confirm the memory is running at 4800 MHz with CL40 timing after installation?

Check the BIOS memory information screen or run a tool such as dmidecode to verify the reported speed of 4800 MT/s and CAS latency of 40 cycles.
