Purpose-built server kit

This 1 TB kit contains eight 128 GB DDR5 RDIMMs tuned for the Supermicro H13SSH motherboard. Registered ECC architecture lets every slot run fully populated while correcting single-bit errors on the fly. System builders who need exact-rank compliance for production workloads will find the modules recognised at rated speed without manual tuning. It is not for desktops or boards that accept only unbuffered memory.

Build and connectors

Each module uses the 288-pin RDIMM form factor with a 2Rx4 organisation and operates at 1.1 V. The registered design buffers address and command signals so the memory controller stays stable across all populated channels. No heat spreaders are fitted, so airflow in dense chassis must be sufficient for sustained loads. Buyers who require passive cooling accessories or low-profile clearance should verify their chassis specifications first.

Deciding specification

The kit runs at DDR5 4800 with CL40 latency, matching the PC5-38400 data rate the H13SSH memory controller expects. Population rules for this platform are strict; the manual defines supported capacities per channel and the required installation order. Deviating from that order can prevent the system from booting or limit usable capacity.

Questions about this item

Does the DDR5-4800 PC5-38400 interface run at its rated 4800 MT/s on the Supermicro H13SSH board?

Yes, the kit is spec-matched to the board's memory controller so all eight modules operate at the full 4800 MT/s transfer rate with CL40 latency.

What physical slot and form factor do these modules need on the Supermicro H13SSH motherboard?

The board requires 288-pin DDR5 RDIMM slots; this kit provides eight 288-pin registered DIMMs that match that exact form factor.

How are the eight 128 GB modules installed, and which population step is often missed?

Follow the motherboard manual's approved DIMM population order for all eight slots; the step often missed is using the exact sequence the manual specifies for full 1 TB capacity.
