ThinkMate GPX-WS-540X1 DDR4 Kit

This NEMIX RAM kit supplies 32 GB of DDR4 3200 memory in four matched 8 GB modules built for the ThinkMate GPX-WS-540X1 workstation. Each stick is a 288-pin unbuffered UDIMM running at 1.2 V with CL22 latency. The modules use major OEM chips from Samsung, Micron or Hynix and carry no heat spreader. They are tested for stability under load in the target platform.

Suited for compatible workstations needing 32 GB

Builders upgrading a ThinkMate GPX-WS-540X1 that accepts non-ECC unbuffered DDR4 UDIMMs can install this kit directly. Systems that require registered or ECC memory, or platforms limited to lower speeds or voltages, cannot use these modules. Buyers needing capacities beyond 32 GB must look for a different configuration.

32 GB DDR4 3200 CL22 288-pin UDIMM

The single specification that decides fit is the combination of DDR4 3200 speed, CL22 timing, 1.2 V operation, non-ECC unbuffered design and 288-pin UDIMM form factor in a 32 GB (4×8 GB) kit. If the workstation’s memory controller demands ECC, registered modules or a different pin count, this kit will not work.

Questions about this item

Does the CL22 latency limit bandwidth under sustained loads?

CL22 is the rated CAS latency at DDR4 3200; sustained throughput depends on the workstation memory controller and workload.

How much heat and power do four 1.20 V modules produce all day?

Each 8 GB UDIMM runs at 1.20 V without a heat spreader; total power scales with the number of active ranks in the ThinkMate GPX-WS-540X1.

What must the workstation already have to accept this 4 x 8 GB kit?

Four free 288-pin DDR4 UDIMM slots and a motherboard qualified for non-ECC unbuffered PC4-25600 memory.
