Exact-match server upgrade

This 64GB DDR5 RDIMM is built for the Supermicro H13SSW motherboard. It delivers registered ECC memory in the 288-pin form factor that the board requires. The module targets administrators who need verified fitment for production servers.

Registered ECC with 2Rx4 organisation

The single specification that decides compatibility is the 2Rx4 registered ECC layout at 1.1V. This rank structure and voltage match the memory controller expectations so the system recognises the full capacity at rated speed. Builders who need unbuffered UDIMMs or a different rank configuration cannot use this part.

Low-voltage DDR5 operation

At 1.10V the modules draw minimal power while running at 4800MHz CL40. The registered architecture reduces electrical load on the memory controller when all slots are populated. No heat spreader is fitted, so airflow across the DIMM slots handles thermal dissipation in normal server chassis.

Questions about this item

What does the 4800 MHz speed mean once the module is installed in a Supermicro H13SSW?

The DDR5-4800 rating means the memory controller will run this kit at 4800 MT/s with CL40 timings at 1.1 V, giving the full 64 GB capacity per module without down-clocking.

What does the PC5-38400 designation tell me about the interface and its practical limit?

PC5-38400 is the DDR5-4800 bandwidth designation; the 288-pin RDIMM interface delivers that peak rate only when the motherboard populates the slot according to its memory-population rules.

What physical requirements must the Supermicro H13SSW meet to accept this 288-pin RDIMM?

The board needs a standard DDR5 288-pin RDIMM slot and must support registered ECC modules in a 2Rx4 configuration at 1.1 V.
