  • 768 GB total capacity from twelve 64 GB modules for maximum memory density
  • DDR5 5600 speed with CL46 latency delivers rated throughput for Supermicro H13SST-GC
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation at 2Rx4 rank matches the motherboard memory controller exactly
  • 288-pin RDIMM form factor fits the board's required DIMM slots precisely

Exact-match DDR5 kit for Supermicro H13SST-GC

This 768GB kit contains twelve 64GB DDR5 RDIMMs rated at 5600MHz with CL46 latency and 1.1V operation. Registered ECC architecture with 2Rx4 organisation is designed for the Supermicro H13SST-GC motherboard so the memory controller recognises full capacity at rated speed.

Suited for fully populated server builds.

The registered RDIMM form factor and ECC function require a server platform that supports registered memory population rules. Builders using consumer motherboards, workstations needing UDIMM or SODIMM modules, or systems limited to lower maximum capacities should select a different kit.

768GB across twelve slots with registered buffering

Twelve modules fill every slot on the H13SST-GC while the registered design offloads the memory controller for stable operation at full population. ECC corrects single-bit errors on the fly to prevent silent data corruption. Systems needing more than 768GB or a different DIMM count must consult the motherboard manual for supported configurations.

Questions about this item

What motherboard must I already own for this 12-module 768GB DDR5 kit to be recognised at full capacity?

The kit is validated for the Supermicro H13SST-GC motherboard; the board's memory controller expects exactly this 2Rx4 registered ECC configuration at 1.10 V and CL46.

If I keep older DDR5 RDIMMs in the same Supermicro H13SST-GC, how will this 5600 MHz CL46 kit behave?

All slots will run at the speed of the slowest installed modules, so the new 5600 MHz sticks will down-clock to match the older DIMMs' data rate and latency.

After installing all 12 modules, how can I confirm the system is using the full 768 GB at DDR5-5600?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 12 × 64 GB RDIMMs operating at 5600 MT/s with CL46 timings.
