System-specific DDR4 kit for Thinkmate workstations

This 32 GB kit contains two 16 GB DDR4 3200 UDIMM modules built for the Thinkmate GPX-WS-540X1. Each stick runs at 1.2 V with CL22 latency and uses a 2Rx8 rank layout. The memory is non-ECC and unbuffered, matching the workstation's standard desktop memory slots. It is intended for users expanding capacity on this exact platform.

Verify motherboard slots and memory population rules

Confirm the GPX-WS-540X1 has free 288-pin DDR4 UDIMM slots and supports 2Rx8 modules at 3200 MT/s. Check the system manual for maximum capacity per slot and any required population order across channels. The kit is not compatible with DDR5, registered, ECC or SO-DIMM form factors. Ensure the platform accepts non-ECC unbuffered memory before ordering.

Standard voltage and unbuffered design for typical

Operating at 1.20 V, these modules draw normal power for DDR4 3200 UDIMMs. Without heat spreaders they rely on case airflow across the bare PCB, so adequate chassis ventilation is recommended. Acoustic output is negligible as the sticks have no active cooling. Power consumption scales with the number of populated slots and workload intensity.

Questions about this item

What comes in the 32 GB kit and do I need anything else to install it?

The box contains two 16 GB DDR4 UDIMM modules, giving 32 GB total; no extra parts or cables are required for a standard desktop DIMM slot.

The listing shows DDR4 3200 CL22 1.2 V — is that the only version available for this ThinkMate workstation?

Yes, this kit is specified as DDR4 3200 (PC4-25600) CL22 at 1.2 V in a 2×16 GB 2Rx8 unbuffered configuration.

Will the advertised 3200 MT/s speed run at that rate once the modules are seated in the GPX-WS-540X1?

The modules are rated for 3200 MT/s CL22 at 1.2 V; the workstation’s memory controller will set the final speed, which may be lower depending on BIOS and CPU support.
