  • Verified 288-pin RDIMM fitment for the Supermicro H13SST-GC motherboard

Supermicro H13SST-GC upgrade

This 512 GB kit supplies four 128 GB DDR5 registered ECC RDIMMs built for the Supermicro H13SST-GC motherboard. The modules match the board’s required 288-pin RDIMM form factor and registered architecture so the memory controller recognises every slot at full capacity.

Registered ECC stability

Registered buffering offloads the memory controller while ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. The kit runs at DDR5 5600 with CL46 timing and 1.10 V, exactly as the platform expects.

Full-slot population

Populating all four slots with 2Rx4 modules keeps each channel fully loaded at rated speed without down-clocking. Verify your system manual for approved DIMM population order and maximum supported capacity before installation.

Questions about this item

Will the 2Rx4 DDR5 RDIMM configuration need firmware updates or slot reordering if I expand beyond the 4x128GB kit?

The kit is validated for the Supermicro H13SST-GC at DDR5-5600 with 2Rx4 registered ECC modules. Population rules are defined by the motherboard manual; follow its approved slot order for any additional DIMMs.

What limits sustained throughput first — the CL46 latency or the 5600 MT/s data rate?

At DDR5-5600 (PC5-44800) the 5600 MT/s transfer rate sets the peak bandwidth ceiling; CL46 (46 cycles) determines access latency within that rate.

How much heat and power does the 1.1 V registered ECC kit generate when all four slots run continuously?

Each 128 GB module operates at 1.10 V without a heat spreader; registered buffering reduces controller load, so total power draw stays within standard RDIMM limits for the platform.
