Exact-match DDR5 RDIMM for Supermicro H13SST-G

This 128 GB DDR5 5600 CL46 registered ECC module is built for the Supermicro H13SST-G motherboard. The 2Rx4 rank layout, 1.1 V operation and 288-pin RDIMM form factor match the board's memory controller expectations so the full capacity is recognised at rated speed.

Replaces mismatched or undersized DIMMs

Swapping out slower, lower-capacity or unbuffered sticks removes population errors and lets every slot run fully populated at 5600 MT/s. The jump is worth it when your workload needs the registered architecture to keep all channels stable at maximum density.

128 GB per module with registered ECC headroom

The single-module density handles large in-memory databases, virtualization hosts and HPC datasets without forcing extra slots. Registered buffering and on-the-fly ECC correction keep data intact under sustained load, while the fixed CL46 timing and 1.1 V voltage define the performance ceiling.

Questions about this item

What motherboard slot and pin count does this 128GB DDR5 module require?

It uses the standard 288-pin DDR5 RDIMM form factor that the Supermicro H13SST-G motherboard expects.

Which population rule should I follow when installing this 2Rx4 registered DIMM?

Consult the Supermicro H13SST-G manual for the approved DIMM population order; the board must be populated in that sequence for the memory controller to recognise the full 128GB at 5600MHz.

Will the lack of a heat spreader affect long-term reliability of this 1.1V ECC RDIMM?

The module is specified at 1.1V without a spreader; enterprise registered ECC DIMMs are validated for continuous operation at this voltage in properly cooled server chassis.
