ThinkMate server upgrade

This 512 GB kit contains eight 64 GB DDR4 3200 ECC registered DIMMs built for ThinkMate GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU GPU-optimised servers. It targets administrators who need maximum registered capacity for virtualisation, rendering or compute clusters.

Installation and common issues

The 288-pin RDIMMs install in minutes by seating each module firmly until the retention clips lock; no heat spreader is fitted so clearance is minimal. The main risk is mixing ranks or speeds — all eight slots must use identical 4Rx4 CL22 modules or the system will not post.

Capacity headroom

Eight modules deliver 512 GB at 1.2 V, filling every DIMM slot on the supported platforms and leaving no room for further expansion. Workloads that exceed this limit require a platform with higher-density DIMM support or additional nodes.

Questions about this item

How can I verify the 512GB kit is running at DDR4 3200 with CL22 timings after installation?

Check the BIOS or UEFI memory information screen — it should report 3200 MT/s, CAS latency 22, 1.20 V and 4Rx4 organisation for each of the eight 64 GB modules.

What is included in the package and do I need any extra parts for a Thinkmate GPX-QN4-22E2-4NVLINK server?

The box contains the eight 64 GB DDR4 3200 ECC registered RDIMMs; no additional components are required for the listed Thinkmate GPU-optimised servers.

Which capacity configuration should I choose if my Thinkmate workstation has 24 DIMM slots and I want to populate them evenly?

This 512 GB kit provides eight 64 GB modules, so adding three identical kits would fill all 24 slots with matching 4Rx4 registered DIMMs.
