256GB DDR4 ECC RDIMM kit

This NEMIX RAM kit delivers 256GB across four 64GB DDR4 3200 modules. Each stick is a 288-pin registered DIMM with ECC, 4Rx4 organisation and CL22 latency at 1.20V. It is built for ThinkMate GPX-QN6-42E2-8NVLINK GPU-optimised servers.

Server admins needing maximum registered capacity

The 4Rx4 density suits workloads that demand large memory footprints with error correction. Systems that cannot accept registered modules, that require unbuffered DIMMs, or that are limited to lower ranks per channel should look elsewhere.

Fills four DDR4 RDIMM slots at 3200 MT/s

The kit plugs directly into compatible ThinkMate server boards, providing 256GB without mixing capacities. It frees remaining DIMM slots for future expansion while maintaining registered signal integrity across all populated channels.

Questions about this item

Does my Thinkmate GPX-QN6-42E2-8NVLINK server need DDR4 RDIMM slots to use this 256GB kit?

Yes, the kit uses 288-pin DDR4 RDIMM modules; the server must provide registered DDR4 DIMM sockets that accept 4Rx4 ECC memory.

Can I keep my existing DDR4 3200 CL22 ECC RDIMMs and add these four 64GB modules?

Mixing ranks or capacities is possible only if the motherboard supports mixed 4Rx4 populations; check the Thinkmate manual for qualified configurations.

How do I verify the 3200 MT/s speed and ECC function after installing the 4Rx4 modules?

Enter the BIOS or use a tool such as dmidecode to confirm each DIMM reports 3200 MT/s, CL22, 1.20 V and ECC enabled.
