384GB DDR5-5600 ECC RDIMM kit for Supermicro

This 12-module kit delivers 384GB of DDR5-5600 registered ECC memory built for the Supermicro H13SSL-N motherboard. Each 32GB module runs at CL46 latency and 1.1V, matching the board's memory-controller requirements exactly. System integrators and server operators who need maximum supported capacity in every slot can deploy this kit without population guesswork.

Registered 288-pin RDIMM build

The registered architecture buffers address and command signals so all twelve slots operate at full speed when fully populated. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unexpected reboots in production workloads. The 288-pin DDR5 RDIMM form factor fits only motherboards designed for registered DDR5 modules; it will not work in UDIMM or SODIMM slots.

Twelve matched 32GB modules shipped as a single kit

All twelve DIMMs are tested together and packaged as one 384GB kit, ensuring identical rank, voltage and timing across every stick. The package contains only the memory modules; no additional cables, brackets or software are included. Buyers who need a different total capacity or a non-ECC configuration should look elsewhere, as this kit addresses the specific registered ECC requirement of the target platform.

Questions about this item

Does the DDR5-5600 PC5-44800 interface limit the 384GB kit to a lower speed on the Supermicro H13SSL-N?

The kit runs at the rated DDR5-5600 speed when the motherboard memory controller supports that frequency; the PC5-44800 designation matches the 5600 MT/s data rate.

What physical slot and form factor do the 12 modules require on the H13SSL-N motherboard?

Each 32GB module uses a 288-pin DDR5 RDIMM form factor, so the board must provide 12 DDR5 RDIMM slots.

What is the correct population order for all 12 RDIMMs, and what step is often missed?

Follow the Supermicro H13SSL-N manual for the approved DIMM population sequence; a common mistake is skipping the prescribed slot order, which prevents full 384GB recognition.
