Exact-match DDR5 RDIMM kit for Supermicro H13SRH

This 1 TB kit contains eight 128 GB DDR5-4800 registered ECC modules built to the PC5-38400 standard. The 2Rx4 organization, 1.1 V operating voltage and CL40 latency match the memory controller expectations of the Supermicro H13SRH motherboard so the full capacity is recognised at rated speed.

Registered architecture under sustained load

The registered design buffers address and command signals, reducing electrical load on the memory controller when all eight slots are populated. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during extended production workloads.

288-pin RDIMM installation and population rules

Modules install vertically into the 288-pin DDR5 RDIMM slots; the key notch prevents misalignment. Because server memory support varies by model, consult the system or motherboard manual for approved DIMM population order and maximum supported capacities before installing.

Questions about this item

How much heat and power will eight 128 GB DDR5-4800 RDIMMs add when the server runs continuously?

Each module operates at 1.1 V with no heat spreader, so total power draw scales with all eight slots populated; the registered design reduces electrical load on the memory controller, helping thermals stay manageable in a fully populated H13SRH chassis.

What motherboard and slot requirements must I already have for this 1 TB kit to function?

A Supermicro H13SRH motherboard with eight free 288-pin DDR5 RDIMM slots, supporting 2Rx4 registered ECC modules at 1.1 V and CL40, populated according to the board's memory-installation order.

How will this DDR5-4800 2Rx4 registered ECC kit behave if I keep older DDR5 RDIMMs in the same H13SRH server?

The memory controller will run all populated slots at the lowest common speed and timing; mixing ranks or CAS latencies can prevent the full 1 TB from being recognised or force a downclock below 4800 MT/s.
