Exact-match server upgrade

This 128 GB DDR5 RDIMM is built for the Supermicro H13SST-GC motherboard. It delivers registered ECC memory that the board's controller recognises at full capacity and rated speed. System integrators and IT teams can populate every slot without mixing ranks or voltages.

Thermals noise and power

The modules run at 1.1 V with no heat spreader, relying on the server's directed airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable under sustained workloads. Silent operation is assured because there are no active cooling components on the DIMMs themselves.

2Rx4 registered ECC configuration

The dual-rank x4 organisation with CL46 timing is the specific layout the H13SST-GC memory population rules require. Using a different rank structure or unbuffered DIMMs would prevent the system from booting or reaching the rated 5600 MT/s data rate. Verify your manual for approved slot order before installation.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in my Supermicro H13SST-GC, and which step is often missed?

Power down, open the chassis, and insert the module into the correct DIMM slot following the motherboard's population order; the step most often missed is checking the manual for the approved slot sequence before seating the RDIMM.

What maintenance or replacement will this 128GB ECC Registered module need over time?

No routine maintenance is required; if a correctable error rate rises or a module fails, replace the individual RDIMM — ECC corrects single-bit errors on the fly, but a defective unit must be swapped out.

What limit appears first when this CL46 1.1V kit runs sustained workloads?

The registered buffer and ECC logic keep every slot stable at the rated 5600 speed, so the first limit is the motherboard's maximum supported capacity or slot count, not the memory's own timing or voltage.
