Capacity and form factor

This kit delivers 1 TB of DDR5 server memory as eight 128 GB registered RDIMMs. It is built for administrators upgrading a Supermicro H13DSH motherboard that requires 288-pin ECC modules.

Registered ECC architecture

Registered buffering reduces electrical load on the memory controller so all eight slots can be populated at full speed. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

Speed and headroom

Rated at DDR5-4800 with CL40 latency and 1.1 V operation, the kit runs at the motherboard's native transfer rate. Workloads that exceed 1 TB total capacity or demand lower latency than CL40 will need a different configuration.

Questions about this item

What is the sustained CAS latency of the DDR5-4800 RDIMM kit under continuous load?

The modules run at CL40 timing, which is the rated latency the memory controller expects during sustained operation.

How much heat and power do the eight 128 GB RDIMMs generate when the server runs all day?

Each module operates at 1.1 V with no heat spreader, so power draw and thermal output stay at the standard DDR5-4800 registered DIMM level.

Which motherboard slot layout must the Supermicro H13DSH already have free for this 1 TB kit to work?

The board needs eight open 288-pin DDR5 RDIMM slots populated in the order the manual specifies for 2Rx4 registered modules.
