Server memory upgrade

This 384GB kit delivers six 64GB DDR5-4800 ECC RDIMM modules built for the Supermicro H14SSL-N motherboard. It targets administrators who need maximum registered capacity in a single validated package.

Build integration

The 288-pin RDIMM form factor matches the board's registered slots and population rules, so all channels fill at rated speed without manual tuning. Registered buffering and ECC protect data integrity while the 1.1V operating voltage keeps power draw predictable.

Upgrade path

It replaces smaller or mixed-capacity kits that force the controller to down-clock or limit rank count. The jump is worth it when workloads demand full 384GB registered ECC capacity at DDR5-4800 CL40 without compatibility risk.

Questions about this item

Will the DDR5-4800 speed hold when all six 64GB RDIMMs are populated on the Supermicro H14SSL-N?

The kit is spec-matched to the H14SSL-N population rules, so the full 384GB runs at the rated 4800 MT/s with CL40 timings.

What thermal and power behaviour should I expect from the 1.1V registered ECC modules under continuous load?

Registered buffering offloads the memory controller, and the 1.10V operating voltage keeps power draw low; no heat spreader is fitted, so chassis airflow handles cooling.

Which motherboard slot configuration and firmware settings are required before installing this 6-module kit?

The H14SSL-N manual defines the approved DIMM population order and any BIOS options needed for full-capacity registered ECC operation.
