NEMIX RAM
Eight 128 GB DDR5 RDIMMs deliver 1 TB of registered ECC memory at 6400 MHz with CL52 latency and 1.1 V operation for the Supermicro X14SRA-F motherboard
Size 1TB 8X128GB
This 1 TB kit contains eight 128 GB DDR5-6400 (PC5-51200) registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro X14SRA-F memory controller expects. Each module runs at 1.1 V with CL52 latency and a 4Rx4 organisation across 288 pins.
The registered design buffers address and command signals so every slot remains fully populated at rated speed without overloading the memory controller. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during continuous server workloads.
Install this kit when the platform demands maximum supported capacity and the qualified speed of DDR5-6400 with 4Rx4 registration. The upgrade is worthwhile only if the system manual confirms 1 TB total capacity and the specific population order required for eight modules.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Each 128GB module operates at 1.1V, so the full 8-module kit draws power at that voltage when running at DDR5 6400 speed with CL52 timings.
The kit needs a motherboard with 288-pin DDR5 RDIMM slots that supports Registered ECC memory, 4Rx4 rank configuration, and DDR5 6400MHz operation.
No, the Registered RDIMM form factor and 4Rx4 organization require a motherboard and memory controller designed for Registered ECC DDR5, not UDIMM slots.
