NEMIX RAM
Dual 48GB DDR5 registered ECC RDIMM kit running at 6400MHz with CL52 latency and 1.1V operation
This NEMIX RAM kit delivers 96GB across two 48GB DDR5 6400MHz registered DIMMs. The modules carry ECC and a 2Rx8 organisation for data integrity in multi-socket servers and workstations. They operate at 1.1V and conform to the PC5-51200 standard. The kit is built with major-brand Samsung, Micron or Hynix components.
Confirm that your motherboard accepts 288-pin DDR5 RDIMMs and supports registered ECC memory at 6400MHz. Consumer desktop boards typically cannot use registered modules, so this kit is not for standard PC builds. Check the qualified-vendor list and BIOS revision for 48GB dual-rank DIMM support before ordering. The CAS latency is rated at 52 cycles.
Registered buffering and on-die ECC maintain signal quality during continuous throughput workloads such as virtualisation, database serving or scientific compute. The 1.1V operating voltage helps limit thermal output when all slots are populated for long periods. Error correction operates transparently to prevent silent data corruption under heavy sustained demand.
