  • Total capacity512 GB (8 × 64 GB)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank4Rx4
  • 512 GB total capacity for high-density server workloads
  • DDR5 6400 MHz CL52 for fast data throughput

512GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit provides 512GB of DDR5 memory across eight 64GB registered DIMMs. It operates at 6400MHz with a CAS latency of CL52 and a voltage of 1.10V. The modules use a 4Rx4 rank configuration and include on-die ECC for data integrity. They are designed for compatible Supermicro server platforms.

Verify DDR5 RDIMM Support

Confirm that your motherboard accepts 288-pin DDR5 RDIMM modules and supports a 6400MHz data rate at 1.10V. Check the qualified vendor list for 4Rx4 64GB density support across all eight slots. Ensure the system BIOS is updated to recognise the full 512GB capacity. Registered memory requires a compatible chipset and cannot be mixed with unbuffered DIMMs.

Suits High-Capacity Server Builds

This kit suits administrators maximising memory in supported Supermicro servers for virtualisation or database workloads. It is not for desktop PCs or workstations that require unbuffered UDIMM modules. Builders needing lower capacities or different speeds should select alternative kits. Systems limited to fewer than eight slots cannot use this full configuration.

Questions about this item

Does the 512GB kit ship as eight 64GB modules or do I need to buy additional sticks?

The kit contains eight 64GB DDR5 ECC RDIMM modules for a total of 512GB; nothing else is required for installation.

Should I choose the CL52 6400MHz version or a different latency for my Supermicro X14SBM-TF?

This kit is validated for the Supermicro X14SBM-TF at 6400MHz with CL52 timing; select this exact specification for guaranteed compatibility.

What does the 6400MHz rating mean once the memory is installed in the server?

The modules operate at 6400 MT/s (PC5-51200) with 1.10V and registered ECC, delivering the rated throughput when the platform runs at that speed.
