Supermicro H13SST-GC DDR5 upgrade

This 192GB kit delivers twelve 16GB DDR5 RDIMMs rated at 6400MHz PC5-51200 with CL52 latency and 1.1V operation. Registered ECC architecture ensures data integrity for the Supermicro H13SST-GC motherboard.

288-pin Registered form factor

Each module uses the 288-pin RDIMM format required by the H13SST-GC, not UDIMM or SODIMM alternatives. The 1Rx8 rank configuration matches the board's population rules so all twelve slots can be filled at rated speed without down-clocking.

Enterprise stability at 1.1V

Registered buffering reduces electrical load on the memory controller while ECC corrects single-bit errors on the fly, preventing silent corruption. Low 1.1V operation limits power draw and heat in fully populated server configurations.

Questions about this item

What DDR5 speed and CAS latency does this 12-module kit run at?

The kit runs at DDR5 6400 (PC5-51200) with a CAS latency of CL52 at 1.1 V.

What physical slot type and module count does the Supermicro H13SST-GC require for this upgrade?

The board uses 288-pin DDR5 RDIMM slots; the kit provides exactly 12 modules of 16 GB each to fill the supported channels.

In which order should the 12 RDIMMs be installed on the H13SST-GC?

Follow the motherboard manual's population sequence — typically filling one DIMM per channel first, then the second slot per channel, to ensure all 192 GB are recognised at rated speed.
