768GB DDR5 RDIMM kit for Supermicro H13SST-GC

This 768GB kit contains eight 96GB DDR5-4800 registered ECC RDIMMs built for the Supermicro H13SST-GC motherboard. Each module runs at 1.1V with CL40 latency and a 2Rx4 organisation. The registered design lets every slot run fully populated at rated speed.

Check manual for population rules

Server memory support varies by model and BIOS revision. Consult the system or motherboard manual for approved DIMM population order, maximum supported capacity per slot, and installation steps before ordering. The kit uses 288-pin registered RDIMMs, not UDIMMs or SODIMMs.

Replaces smaller RDIMM sets when full 768GB is

The upgrade is worth it when workloads demand the full eight-module capacity at DDR5-4800 with ECC protection. Registered buffering offloads the memory controller so all slots operate at rated speed. Buyers who need fewer modules or a different capacity should look elsewhere.

Questions about this item

What does the 768GB 8x96GB kit include and is anything else required for installation?

The kit contains eight 96GB DDR5 4800 RDIMM modules, totalling 768GB. No additional parts are needed; install them directly into the Supermicro H13SST-GC motherboard following its population guide.

Should I choose this CL40 2Rx4 kit or a different speed or rank for the H13SST-GC?

This CL40 2Rx4 DDR5-4800 kit matches the exact rank, voltage and timing the H13SST-GC memory controller expects, ensuring full-capacity recognition at rated speed.

What does the DDR5-4800 PC5-38400 rating mean once the modules are running in the server?

The modules will operate at 4800 MT/s with CL40 latency at 1.1V, delivering the bandwidth and error-correcting stability the registered ECC design provides for production workloads.
