Exact-match upgrade for Supermicro H13SST-GC

This NEMIX RAM kit delivers 64GB of DDR5 memory as two 32GB Registered ECC RDIMMs. It is built for the Supermicro H13SST-GC motherboard and matches the board's required 288-pin RDIMM form factor. System integrators and server administrators use it to populate memory slots with the precise rank, voltage, and timing the platform expects.

Registered ECC RDIMM with 2Rx8 organization

The modules operate at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V. Registered buffering offloads the memory controller so every slot runs fully populated at rated speed. On-die ECC catches and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

64GB total capacity in a two-module kit

Two 32GB DIMMs fill a matched pair of slots and leave remaining channels available for future expansion within the motherboard's supported limits. The Registered architecture sustains stability when all approved slots are populated. Capacity headroom ends at the board's maximum supported memory per channel and total DIMM count.

Questions about this item

What does the 6400 MT/s speed mean once the kit is installed in my Supermicro H13SST-GC?

The modules run at DDR5-6400 (PC5-51200) with CL52 latency and 1.10 V, so the memory controller recognises the full 64 GB at rated speed without manual tuning.

How does the 288-pin RDIMM interface and registered ECC design affect what the system can do?

Registered buffering lets every slot stay fully populated at 64 GB while ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots.

What physical space and slot layout does this 2 x 32 GB kit need on the motherboard?

Two adjacent 288-pin DDR5 RDIMM slots are required; the modules have no heat spreader, so they fit standard server DIMM spacing without clearance issues.
