Exact-match server memory kit

This 1.5 TB kit delivers twelve 128 GB DDR5-6400 registered ECC RDIMMs tuned for the Supermicro H13SST-G motherboard. Each module operates at 1.1 V with CL52 latency and a 2Rx4 rank layout. The registered design allows every slot to be populated at full rated speed.

DDR5 registered DIMM limits

Registered DDR5 RDIMMs buffer address and command signals so the memory controller can drive a full complement of modules without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption. The 288-pin form factor fits only DDR5 RDIMM slots; it will not work in UDIMM or SODIMM sockets.

Capacity and rank configuration

The kit provides 1.5 TB total capacity across twelve dual-rank 2Rx4 modules. This specific rank-per-DIMM arrangement must match the motherboard’s qualified vendor list and population rules for the system to recognise the full capacity and run at DDR5-6400. Verify the manual before purchase.

Questions about this item

Should I pick the 12-module 1.5TB kit or a smaller capacity for my Supermicro H13SST-G?

The 12 x 128GB kit fills all slots for the full 1.5TB capacity your board supports; choose a smaller kit only if you need fewer populated slots.

Will the DDR5 6400 speed run at 6400MHz once installed in the H13SST-G?

Yes, the modules are spec-matched to the motherboard so the memory controller recognises them at the rated DDR5 6400 speed.

Does the 288-pin RDIMM interface limit how many modules I can install?

The 288-pin Registered RDIMM form factor is exactly what the H13SST-G requires, allowing all 12 slots to be populated at full capacity.
