NEMIX RAM 256GB (2x128GB) DDR5 6400 CL52 1.1V 2Rx4 ECC RDIMM for Supermicro H13SRA-F H13SRA-TF memory upgrade

Server Memory Kit

This NEMIX RAM kit delivers 256 GB of DDR5 registered ECC memory in a matched pair of 128 GB RDIMMs. It is built for the Supermicro H13SRA-F and H13SRA-TF motherboards that require 288-pin DDR5 modules. The exact rank, voltage and timing match the board's memory controller expectations for full-capacity recognition.

Sustained Workload Stability

Registered architecture buffers the address and command signals so the memory controller remains stable when every slot is populated at the rated 6400 MT/s speed. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption during long-running compute or database tasks. The 1.1 V operating voltage supports consistent operation without thermal throttling under continuous load.

DDR5 Platform Constraints

The DDR5 6400 PC5-51200 interface provides the bandwidth ceiling for this kit; actual throughput depends on the motherboard's memory controller and population rules. Only systems that support 2Rx4 registered DIMMs at this voltage and latency can utilise the full 256 GB capacity. Builders must verify the manual for approved DIMM population order and maximum supported density per channel before installation.
