ThinkMate GPX-QN6-42E2 Server Memory Kit

This 512GB kit contains four 128GB DDR4 3200 ECC registered DIMMs built for the ThinkMate GPX-QN6-42E2-8NVLink GPU-optimised server. Each module runs at 1.2V with CL22 latency and a 4Rx4 organisation using major OEM DRAM. The registered design adds signal integrity for heavy multi-socket workloads.

Suited for ThinkMate GPX-QN6-42E2 upgrades.

IT teams expanding memory in the exact ThinkMate GPX-QN6-42E2-8NVLink chassis can install these modules with confidence. Builders using different motherboards, workstations or desktop systems should look elsewhere because the kit is validated only for this server model.

4Rx4 rank density decides slot population

Every DIMM presents a quad-rank 4Rx4 layout, so the memory controller sees four logical ranks per slot. Planners must verify that the GPX-QN6-42E2 memory subsystem supports this rank density in the desired slot configuration before ordering.

Questions about this item

Will the 288-pin RDIMM modules fit the ThinkMate GPX-QN6-42E2-8NVLink motherboard slots?

The kit contains four 128 GB DDR4 3200 CL22 1.2 V registered DIMMs built to the 288-pin standard used by the ThinkMate GPX-QN6-42E2-8NVLink server.

What is the correct seating order for the four 128 GB 4Rx4 modules during installation?

Install the modules in the sequence shown in the server manual, pressing each DIMM straight down until both retaining clips click to ensure full contact on all 288 pins.

When should the 512 GB 4Rx4 DDR4 3200 CL22 kit be replaced in a mission-critical workload?

Replace the kit if the system logs uncorrectable ECC errors, memory-test failures, or repeated correctable errors that exceed the platform threshold for the 4Rx4 registered modules.
