Exact-fit DDR5 upgrade

This NEMIX RAM kit delivers 384 GB of DDR5 4800 registered ECC memory in eight 48 GB modules built for the Supermicro H14SSF motherboard. Each 288-pin RDIMM operates at 1.1 V with CL40 timing and 2Rx8 organization so the memory controller sees the precise rank and voltage it expects.

Check population rules

Consult the system or motherboard manual for supported capacities and approved DIMM population order before ordering. The board requires 288-pin registered RDIMMs rather than UDIMMs or SODIMMs and full-slot configurations must follow the vendor's installation sequence.

Lifetime support included

The package contains the eight-module kit only with no heat spreaders or extra cables. A lifetime replacement warranty and free US-based technical support cover the modules after installation.

Questions about this item

Does the 8 x 48 GB kit ship as a ready-to-install set, or must I add anything else?

The package contains the full 384 GB kit — eight 48 GB DDR5-4800 registered ECC RDIMMs — so nothing else is needed for the memory upgrade.

My H14SSF board supports several DDR5 speeds; why choose the 4800 MT/s CL40 version?

This kit matches the exact speed, voltage, rank and timing the H14SSF memory controller expects, ensuring full-capacity recognition at rated DDR5-4800 without down-clocking.

What does the registered ECC design actually do once the modules are seated in the server?

Registered buffering offloads the memory controller so all slots run fully populated at 4800 MT/s, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
