256GB DDR5 ECC RDIMM Kit

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.

Suited For Supermicro Servers

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.

Verify Platform Compatibility

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.

Questions about this item

Does my Supermicro SSG-521E-E1CR24H have enough DDR5 RDIMM slots for all eight 32GB modules?

The kit contains eight 288-pin DDR5 RDIMMs; confirm your server provides at least eight DDR5 RDIMM slots before installation.

Can I keep my existing DDR5 4800 ECC RDIMMs and add this 256GB kit without speed or voltage mismatch?

Matching 4800 MT/s speed, 1.1V voltage, CL40 latency and 1Rx4 rank lets the new modules run alongside identical DDR5 ECC RDIMMs.

How do I confirm the full 256GB kit is recognised and ECC is active after install?

Enter the server BIOS and verify the memory summary shows 256GB total with ECC enabled for each populated slot.
