Exact-match DDR5 kit for Supermicro H13SST-G

This 64GB kit contains four 16GB DDR5 6400 RDIMM modules built to the board's required 1.1V, CL52, 1Rx8 registered ECC specification. It targets administrators upgrading a Supermicro H13SST-G server who need guaranteed recognition at full capacity and rated speed.

Registered ECC architecture

The registered design offloads the memory controller so all four slots run fully populated while ECC corrects single-bit errors on the fly. The precise 1Rx8 rank, 1.1V voltage and CL52 timing match what the server's memory controller expects, preventing silent data corruption and unplanned reboots.

288-pin DDR5 RDIMM form factor required

The motherboard accepts only 288-pin registered DDR5 DIMMs, not UDIMM or SODIMM variants. Buyers who need a different pin count, voltage or unbuffered modules must select another product.
