Exact-fit DDR5 RDIMM kit

This NEMIX RAM kit delivers 128GB across eight 16GB DDR5-4800 Registered ECC modules built to the Supermicro H14SHM motherboard's exact specifications. Each 288-pin RDIMM operates at 1.1V with CL40 latency and 1Rx8 organisation, matching the memory controller's expectations for full-capacity recognition at rated speed.

Replaces partial or mismatched sets

The kit upgrades systems running with fewer populated slots, slower DDR5 speeds or unbuffered memory that cannot address the full 128GB configuration. The jump is worthwhile when your workloads need every channel filled with registered ECC modules to maintain stability under sustained server loads.

Verify population rules first

Check your H14SHM manual for approved DIMM slot order, maximum supported capacity per channel and any BIOS version requirements before installing all eight modules. Confirm the board accepts 1Rx8 Registered ECC RDIMMs at DDR5-4800 and that your chassis provides clearance for the full eight-module array.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H14SHM motherboard slots?

Yes, the kit uses the exact 288-pin Registered DDR5 form factor the H14SHM requires, so every module seats correctly in the board's memory slots.

What is the correct population order when installing all eight 16 GB modules?

Follow the motherboard manual's approved DIMM population sequence; the board's memory controller expects a specific slot order to recognize the full 128 GB at DDR5-4800.

Do the modules need active cooling since they have no heat spreader?

The RDIMMs run at the standard 1.1 V without a heat spreader; ensure the server chassis provides adequate airflow over the memory slots for stable operation.
