64GB DDR5-4800 ECC RDIMM Kit

This NEMIX RAM kit provides 64GB of DDR5 memory across four 16GB registered DIMMs. It runs at 4800MT/s with a CL40 latency and operates at 1.1V. The modules are designed specifically for Thinkmate SuperServer 611C-TN4R and 621C-TN12R systems.

Suited for registered DDR5 servers; not for desktops

These registered ECC RDIMMs require a server or workstation motherboard that supports registered DDR5 memory. They will not function in standard consumer desktop boards or laptops that accept only unbuffered memory. Buyers needing non-ECC or unbuffered modules should look elsewhere.

288-pin DDR5 RDIMM form factor

The kit uses the standard 288-pin DDR5 RDIMM physical interface with a 1Rx8 rank configuration. Compatibility is validated for the listed Thinkmate SuperServer models. Verify your system requires registered ECC DDR5 before purchase.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Thinkmate SuperServer 611C-TN4R and 621C-TN12R memory slots?

Yes, the kit is built for those two SuperServer models and uses the standard 288-pin DDR5 RDIMM form factor their slots require.

Do I need to populate all four channels with the 1Rx8 modules in a specific order?

Install the four 16 GB modules in the slots your motherboard manual designates for a four-DIMM population; the 1Rx8 organisation works with the standard channel layout.

When should I expect to replace the 1.1 V registered ECC modules under heavy server workloads?

Registered ECC DDR5 at 1.1 V is rated for continuous operation; replacement is only needed if a module fails or capacity requirements grow beyond 64 GB.
