Exact-match upgrade for Supermicro H13SST-GC

This kit delivers 1 TB of DDR5 registered ECC memory in eight 128 GB modules. The 2Rx4 organization, 1.10 V operating voltage and CL40 timing match the controller expectations of the Supermicro H13SST-GC motherboard. It is built for servers that require full-capacity population across all slots.

Verify DIMM population rules before ordering

Server and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps. The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function.

Registered ECC architecture maintains stability

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production environments. No heat spreader is included on the modules.

Questions about this item

Does the kit include all eight 128 GB modules or must any DIMMs be purchased separately?

The package contains the full 1 TB kit — eight 128 GB DDR5 4800 RDIMMs — so nothing else is needed to reach the stated capacity.

How do I decide between this CL40 2Rx4 kit and another speed or rank option?

Choose this kit when your Supermicro H13SST-GC requires DDR5 4800 CL40 2Rx4 registered ECC; other speeds or ranks will not match the board's qualified memory list.

Will the memory run at the rated 4800 MT/s once installed in the H13SST-GC?

Yes, the modules are spec-matched to the motherboard's memory controller, so the system recognises the full 1 TB at DDR5 4800 with CL40 timings.
