NEMIX RAM
Eight 32 GB DDR5 registered ECC modules running at 4800 MT/s CL40 1.1 V for Supermicro servers
This kit provides 256GB of DDR5 4800 registered ECC memory across eight 32GB modules. It is built for Supermicro servers and workstations that require registered DIMMs with error correction. The 1.10V operating voltage and CL40 latency match the platform specifications. IT professionals upgrading compatible Supermicro systems will find this configuration validated for those workloads.
This memory suits administrators expanding Supermicro Storage SuperServer SSG-521E-E1CR24H, SSG-521E-E1CR24L or X13SEDW-F platforms that accept 288-pin DDR5 RDIMMs. Builders needing unbuffered UDIMMs, non-ECC modules or speeds above 4800 should look at other product lines. Systems limited to fewer than eight DIMM slots or a lower maximum capacity per slot cannot use the full kit.
Confirm the target motherboard supports 288-pin DDR5 RDIMMs at 4800 MT/s with 1Rx4 organisation and registered ECC operation. Check the qualified-vendor list for the exact part number MR38400-314K8 or an equivalent 8x32GB configuration. Ensure the BIOS version in use recognises the full 256GB population across all channels before ordering.

The kit contains eight 288-pin DDR5 RDIMMs; confirm your server provides at least eight DDR5 RDIMM slots before installation.
Matching 4800 MT/s speed, 1.1V voltage, CL40 latency and 1Rx4 rank lets the new modules run alongside identical DDR5 ECC RDIMMs.
Enter the server BIOS and verify the memory summary shows 256GB total with ECC enabled for each populated slot.
