Supermicro H13SSH DDR5 upgrade

This 256 GB kit contains two 128 GB DDR5 4800 registered ECC RDIMMs built for the Supermicro H13SSH motherboard. Each module runs at 1.1 V with CL40 timing and a 2Rx4 organisation so the board recognises the full capacity at rated speed.

Sustained enterprise workloads

Registered buffering reduces electrical load on the memory controller allowing every slot to stay populated at full density during continuous operation. On-die ECC detects and corrects single-bit errors in real time preventing silent data corruption that would otherwise crash production services.

DDR5 RDIMM platform limits

The 288-pin RDIMM form factor fits only motherboards wired for registered DDR5 memory; UDIMM or SODIMM systems cannot accept these modules. Population rules and maximum supported capacity vary by BIOS revision so the system manual must be consulted before installation.

Questions sur cet article

How much power does the 1.1 V DDR5 4800 kit draw when the Supermicro H13SSH runs fully populated all day?

Each 128 GB module operates at 1.10 V; total draw depends on the platform's memory-controller load and cannot be stated without board-level measurements.

What motherboard slot and population rules must the H13SSH already provide for this 288-pin RDIMM kit to work?

The board needs DDR5 RDIMM slots wired for registered ECC and must follow the manual's population order for 2Rx4 modules.

Will the CL40 2Rx4 registered ECC modules run at rated speed alongside older DDR5 RDIMMs already installed in the H13SSH?

Mixing ranks or timings forces the controller to the slowest common settings; the manual should be checked for supported mixed-population configs.
