Exact-match DDR5-4800 RDIMM for Supermicro H13SST-GC

This 64 GB registered ECC module runs at DDR5-4800 (PC5-38400) with CL40 latency at 1.10 V. The 2Rx4 organisation and 288-pin RDIMM form factor match the memory controller requirements of the Supermicro H13SST-GC motherboard so the system recognises the full capacity at rated speed. It is built for servers that demand registered DIMMs with on-die error correction.

Upgrade from slower or smaller DDR5 RDIMMs

Replacing lower-capacity or lower-speed registered DDR5 DIMMs with this 64 GB CL40 kit lets you fill every supported slot at the board's native 4800 MT/s rate. The jump is worthwhile when the workload needs maximum registered DIMM density per channel and the platform's qualified-vendor list includes this exact rank, voltage and timing combination. Systems limited to UDIMMs or SODIMMs cannot use this module.

Limited to platforms qualified for 2Rx4 registered

The DDR5 interface here operates only at the single JEDEC speed grade of 4800 MT/s with 1.10 V signalling. Boards that require different ranks, voltages or unbuffered DIMMs will not post with this module installed. Population rules, maximum capacity per channel and supported DIMM counts are defined by the motherboard firmware and must be verified in the system manual before installation.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the Supermicro H13SST-GC motherboard slots?

Yes, the module uses the 288-pin RDIMM form factor required by the H13SST-GC and matches the board's DDR5 memory-controller specification.

What is the correct installation order for this 2Rx4 registered ECC module?

Install modules in the population sequence shown in the Supermicro H13SST-GC manual; registered DIMMs must fill slots in the prescribed order so the memory controller initialises every rank at 4800 MHz.

Does the lack of a heat spreader mean this 1.1 V module needs extra airflow?

The module runs at the standard 1.1 V DDR5 voltage; adequate chassis airflow per the server manufacturer's guidelines is sufficient — no additional cooling is required.
