384GB DDR5 ECC RDIMM kit for Supermicro H13SSH-E

This six-module kit delivers 384GB of registered ECC DDR5 memory built to the exact rank, voltage and timing the Supermicro H13SSH-E memory controller expects. Each 64GB module runs at 4800 MT/s with CL40 latency at 1.1V, allowing the board to recognise full capacity and operate at rated speed without manual tuning.

Thermals power and noise in normal server use

The modules carry no heat spreader, relying on chassis airflow to maintain operating temperature within JEDEC limits for registered DDR5. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable across all six slots. Silent operation is inherent because no active cooling is attached to the DIMMs themselves.

What the bundled kit changes for deployment

The package supplies six matched 64GB RDIMMs in a single validated kit, eliminating the risk of mixing incompatible ranks or voltages that can prevent boot or limit capacity. ECC and registered architecture work together to correct single-bit errors on the fly and offload the controller, reducing unplanned reboots in production workloads. Installers must still follow the motherboard manual for approved population order and maximum supported capacity per channel.

Questions about this item

How do I install these 288-pin DDR5 RDIMMs in the Supermicro H13SSH-E and which population step is often missed?

Power down, open the chassis, and insert each 64 GB module into the slots specified by the motherboard manual for a six-DIMM configuration; the step most often missed is following the exact population order so the memory controller recognises all 384 GB at 4800 MT/s.

What maintenance or replacement will this 2Rx4 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; replacement is only necessary if a module fails, at which point the lifetime warranty covers a swap.

What limit appears first when the kit runs at 4800 MT/s CL40 1.1 V under sustained load?

The registered buffer and ECC logic keep signal integrity stable, so the first practical limit is the motherboard's maximum supported capacity and slot count rather than the memory's own timing or voltage ceiling.
