NEMIX RAM
A 1 TB registered DDR5 kit of sixteen 64 GB modules at 4800 MT/s with ECC and CL40 latency for ThinkMate Supermicro SuperServer 521C-NR
This 1 TB memory kit contains sixteen 64 GB DDR5 4800 registered DIMMs with ECC. It is built for ThinkMate Supermicro SuperServer 521C‑NR systems that require registered error‑correcting memory.
Modules slot into the 288‑pin DDR5 sockets on the motherboard; the registered buffer adds a slight delay so the memory controller must support registered DIMMs. Mixing registered and unbuffered modules or exceeding the board’s maximum rank count will prevent the system from posting.
The kit delivers 1 TB total capacity at DDR5 4800 (PC5‑38400) with CL40 latency and 1.10 V operation. Only servers qualified for 16 × 64 GB 2Rx4 registered ECC modules at this speed can use the full configuration.
