ThinkMate DDR5 4800 ECC RDIMM kit

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.

Installing registered DIMMs in a server chassis

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.

Capacity and speed that define compatibility

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.

Questions about this item

How can I verify the 16 modules are running at 4800 MT/s with CL40 after installation?

What exactly ships in the box and is anything else required to complete the upgrade?

The kit contains 16 registered 288-pin DDR5 ECC RDIMMs (64 GB each, 2Rx4, 1.1 V, CL40). No extra cables, brackets or software are included or needed.

Should I choose this 1 TB 16×64 GB kit or a different capacity for my Thinkmate SuperServer 521C-NR?
