Server memory kit for Supermicro H14SSL-N

This 384 GB kit contains eight 48 GB DDR5 4800 RDIMM modules built to the exact rank, voltage and timing the board expects. Registered ECC architecture lets the memory controller address every slot at full capacity while correcting single-bit errors before they reach production workloads.

For administrators populating all eight slots

Suited for teams that need the full 384 GB recognised at rated speed without manual tuning. Not for builds that require UDIMM or SODIMM form factors, non-ECC operation, lower-density modules or a different DDR generation.

Straightforward 288-pin RDIMM installation

Insert each module into the slots specified by the motherboard manual in the approved population order. Common issues arise when the manual’s sequence is ignored, when mixed-rank DIMMs are added, or when the system BIOS has not been updated to support the full configuration.

Questions about this item

What motherboard must I already have for this 384GB DDR5 4800 kit to work?

The kit is validated for the Supermicro H14SSL-N motherboard, which uses 288-pin DDR5 RDIMM slots and follows the board's specific population rules.

How will these 2Rx8 CL40 registered modules behave if I keep existing DDR5 RDIMMs in the other slots?

Mixing ranks or timings can force the memory controller to downclock all channels; the manual for the H14SSL-N defines which slot combinations are supported at full 4800 speed.

How can I confirm the full 384GB is recognised and running at DDR5 4800 CL40 after installation?

Check the BIOS memory information screen or run dmidecode in Linux; it should show eight 48GB modules at 4800 MT/s with CL40 and ECC enabled.
