NEMIX RAM

NEMIX RAM 576GB 6x96GB DDR5 6400 CL52 1.1V ECC RDIMM Supermicro H13SST-GC memory upgrade

SKU CH-F4J4-GDHB6

Six 96 GB DDR5 RDIMMs deliver 576 GB of registered ECC memory at 6400 MT/s for the Supermicro H13SST-GC motherboard

  • Total capacity576 GB (6 × 96 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Exact DDR5-6400 CL52 timing matches the Supermicro H13SST-GC controller so the 576GB kit runs at rated speed
  • Registered ECC RDIMM architecture offloads the memory controller and corrects single-bit errors for stable full-capacity operation
  • Six 96GB 2Rx4 modules at 1.1V populate every slot without voltage or rank conflicts
  • 288-pin RDIMM form factor fits the board's memory-population rules and is not a UDIMM or SODIMM
  • Lifetime replacement warranty with free US-based technical support backs the upgrade long-term

Capacity and compatibility

This kit provides 576GB of DDR5 memory across six 96GB Registered ECC RDIMMs built for the Supermicro H13SST-GC motherboard. The 288-pin modules match the board's required form factor and population rules exactly.

Sustained operation

Registered buffering reduces electrical load on the memory controller so all slots remain stable when fully populated at 6400 speed. ECC corrects single-bit errors continuously, preventing silent data corruption during long-running workloads.

Interface limits

DDR5 at 6400 with CL52 latency and 1.1V voltage defines the operating envelope of these modules. The 2Rx4 rank structure and PC5-51200 rating set the bandwidth and timing boundaries the platform can utilise.

Questions about this item

How much power does the 6400 MHz kit draw at 1.10 V when the server runs continuously?

Each 96 GB module operates at 1.10 V; the registered design reduces electrical load on the memory controller so all six slots stay populated at full speed without extra voltage.

What motherboard feature must my Supermicro H13SST-GC already provide for these 288-pin RDIMMs to function?

The board must support DDR5 registered ECC memory with 2Rx4 organisation and a 6400 MT/s data rate; the kit matches the exact rank, voltage and timing the controller expects.

Will the CL52 registered ECC modules work alongside any older DDR5 DIMMs I keep in the same system?

Mixing different speeds, ranks or latencies forces the controller to run all channels at the lowest common settings, so population rules in the motherboard manual should be followed for stable operation.
