576GB DDR5 ECC RDIMM kit for Supermicro H13SST-GC

This 12-module kit delivers 576GB of DDR5 4800 registered ECC memory in a single package. It is built for the Supermicro H13SST-GC motherboard and matches the board's required 288-pin RDIMM form factor. System administrators handling large datasets or virtualised workloads gain a validated, full-capacity upgrade without mixing modules.

Registered 2Rx8 modules with no heat spreader

Each 48GB module uses a 2Rx8 registered design that buffers address and command signals so all twelve slots can run fully populated at rated speed. The 1.1V operating voltage and CL40 latency are the exact figures the memory controller expects. Absence of a heat spreader keeps the modules compatible with dense server chassis where clearance is tight.

576GB total capacity in twelve 48GB RDIMMs

The kit provides 576GB across twelve 288-pin DDR5 RDIMMs rated at 4800 MT/s with ECC and registered buffering. This capacity ceiling is the deciding factor: the board must support 48GB per slot and twelve slots populated simultaneously. Verify the motherboard manual for approved population rules before ordering.

Questions about this item

What speed does the DDR5 4800 RDIMM kit run at on the Supermicro H13SST-GC?

The kit is rated for DDR5 4800 (PC5-38400) with CL40 timing at 1.1 V, and the motherboard will recognise it at that speed when populated per its rules.

Does the 288-pin RDIMM form factor fit the Supermicro H13SST-GC DIMM slots?

Yes, the 288-pin Registered RDIMM form factor matches the slots on the H13SST-GC; UDIMM or SODIMM modules will not fit.

What population order should I follow when installing all 12 modules?

Consult the H13SST-GC manual for the approved DIMM population sequence and install the 12 modules in that exact order to achieve full 576 GB capacity.
