384 GB DDR5 ECC RDIMM kit

This 384 GB kit consists of eight 48 GB DDR5-4800 registered ECC modules built for servers that require 288-pin RDIMMs. It targets administrators upgrading a Supermicro H13SSH motherboard or a compatible platform that demands exact rank, voltage and timing alignment.

Capacity and headroom

Eight dual-rank 48 GB modules fill every slot on supported boards, delivering the full 384 GB at the rated 4800 MT/s speed with CL40 latency and 1.10 V operation. Registered buffering offloads the memory controller so all slots run stably at maximum population, while ECC corrects single-bit errors before they affect production workloads.

Verified Supermicro H13SSH fitment

The kit is validated for the Supermicro H13SSH motherboard, matching its 288-pin RDIMM form factor, 2Rx8 organisation, 1.10 V requirement and DDR5-4800 (PC5-38400) specification. Consult your system manual for approved DIMM population order and maximum supported capacity before installation.

Questions about this item

Will the 8×48GB 2Rx8 RDIMM kit run at 4800MHz alongside existing DDR5 modules already installed in my Supermicro H13SSH?

The kit is spec-matched to the H13SSH memory controller for DDR5-4800 CL40 at 1.1V. Mixing ranks or speeds can force the controller to down-clock all slots, so populate remaining channels with identical 2Rx8 4800MHz modules for full rated performance.

How can I confirm the 384GB kit is detected at full speed and ECC is active after installation?

Enter the BIOS and verify total memory reads 384GB, speed shows 4800MT/s, and ECC status reports enabled. In the OS, run dmidecode or lshw to confirm each DIMM registers as 48GB 2Rx8 Registered ECC at 4800MHz.

What exactly ships in the box and do I need any extra brackets or cables for the H13SSH?

The box contains eight 48GB 288-pin DDR5 RDIMM modules — no heat spreaders, brackets, cables or tools. The H13SSH uses standard RDIMM slots, so nothing else is required beyond following the board's population order in its manual.
