  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank4Rx4
  • 512 GB total capacity supports large-scale workloads
  • DDR5 6400 MHz speed delivers high bandwidth
  • ECC registered design protects data integrity
  • 10 V operation reduces power draw

Capacity & Configuration

This kit delivers 512GB of DDR5 memory across eight 64GB registered DIMMs. It is built for Supermicro servers and workstations that require ECC protection and high density for virtualisation, AI training or large databases.

Compatibility Check

Verify that your Supermicro X14SBW-TF motherboard supports 4Rx4 registered modules at 6400MHz and 1.10V. Confirm the board has eight free 288-pin DDR5 slots and that the BIOS is updated for this capacity and rank configuration.

Ideal Use & Limits

Suits administrators scaling memory on the named Supermicro platform for memory-intensive workloads. Not suited for consumer desktops, laptops or any system that accepts only unbuffered non-ECC DDR5 or lacks the required eight-slot layout.
