Capacity and fit

This 48 GB kit delivers six 8 GB DDR4 3200 modules built for the ThinkMate GPX-WS-540X1 workstation. It targets IT professionals and power users who need maximum supported memory in that specific platform.

Build and connectivity

Each stick is a 288-pin UDIMM running at 1.20 V with CL22 timings and a 1Rx8 layout using major OEM DRAM chips. The unbuffered non-ECC design slots straight into standard desktop DIMM sockets without extra cabling or cooling hardware.

Upgrade context

The kit replaces smaller-capacity DDR4 sets when workloads demand the full 48 GB ceiling of the compatible workstation. It is not suited for systems that require registered or ECC memory, nor for platforms limited to lower densities or slower speeds.

Questions about this item

Does the DDR4-3200 PC4-25600 interface limit throughput on the ThinkMate GPX-WS-540X1?

The kit runs at DDR4 3200 (PC4-25600), so maximum bandwidth is capped at that data rate regardless of motherboard capability.

What physical clearance is required for the 288-pin UDIMM modules without heat spreaders?

Each module is a standard-height 288-pin UDIMM with no heat spreader, fitting typical desktop DIMM slots and low-profile CPU coolers.

How are the six 1Rx8 modules installed, and which slot order mistake should be avoided?

Populate all six slots following the motherboard’s channel sequence (usually alternating channels); the common error is filling one channel completely before the second.
