  • 768 GB capacity across six 128 GB modules expands server memory headroom for large workloads
  • DDR5 5600 speed with CL46 latency delivers rated throughput for Supermicro H13SST-GC
  • Registered ECC design corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the motherboard's memory-controller specification for reliable recognition
  • 288-pin RDIMM form factor fits the board's required slot type exactly

Exact-fit server kit

This 768GB kit assembles six 128GB DDR5 registered ECC RDIMMs tuned to 5600 MT/s with CL46 latency at 1.10 V. It is built for the Supermicro H13SST-GC motherboard, matching the 288-pin RDIMM form factor and 2Rx4 rank layout that the board's memory controller expects for full-capacity operation.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot remains stable when all six modules run fully populated at rated speed. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during continuous production workloads.

Upgrade scope and limits

The kit replaces partial or lower-capacity DDR5 RDIMM sets when the platform calls for the full 768GB at 5600 MT/s. It is not suited for systems that require UDIMM or SODIMM form factors, non-ECC operation, or speeds and voltages outside the specified DDR5 5600 1.10 V profile.

Questions about this item

How much heat will the six 128GB DDR5 RDIMMs generate running continuously at 5600MHz?

Each module operates at the standard DDR5 1.10V without a heat spreader, so sustained load produces typical registered-DIMM thermals; ensure your chassis airflow follows Supermicro H13SST-GC population guidelines.

What must the server already have to accept this 768GB kit?

The Supermicro H13SST-GC motherboard with enough free 288-pin DDR5 RDIMM slots for all six modules and a BIOS that supports 2Rx4 registered ECC at PC5-44800 CL46.

Will these DDR5-5600 modules downclock reliably if I keep older DDR5-4800 sticks in the same system?

This kit is validated for the H13SST-GC at its rated 5600MHz CL46; mixing speeds is not covered by the compatibility data, so populate all slots with this matched 6x128GB set for guaranteed operation.
