64 GB DDR4 ECC RDIMM kit

This 64 GB kit contains four 16 GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It is built for ThinkMate GPU-optimised servers that require registered memory for stable operation under heavy workloads.

Tool-free DIMM installation

The 288-pin modules seat in standard DDR4 RDIMM slots without extra tools or cables. Registered signalling and ECC require a compatible server motherboard; mixing with unbuffered DIMMs or populating unsupported slot configurations will prevent the system from posting.

Sustained load stability

All modules are stress-tested under load at 1.20 V to verify reliability during continuous operation. The 2Rx8 organisation and registered buffer help maintain signal integrity when all four slots are populated for extended compute tasks.

Questions about this item

How can I confirm the 64GB kit is running at 3200 MT/s with CL22 after installation?

Enter the BIOS or UEFI and verify the memory speed shows 3200 MT/s and CAS latency 22; the registered ECC modules will also report ECC active in system monitoring tools.

What is included in the package and do I need any extra parts?

The box contains four 16GB 288-pin DDR4 RDIMM modules for a total of 64GB; no additional components are required for installation in a compatible ThinkMate server.

Which capacity version should I choose for a ThinkMate GPU-optimised server?

This 64GB (4x16GB) kit matches the qualified configuration for ThinkMate GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU servers.
