Targeted Upgrade Kit

This 64GB kit contains four 16GB DDR4 UDIMMs validated for the Thinkmate GPX-WS-540X1 workstation. It is built for IT professionals who need a guaranteed compatibility path when expanding system memory for virtualization or data-intensive workloads.

Build Integration

The modules are non-ECC unbuffered DIMMs that install directly into standard 288-pin DDR4 slots without requiring registered memory support. Using four slots to reach 64GB leaves no spare DIMM sockets on a typical four-slot board, so maximum capacity is reached in a single step.

Thermal and Power Profile

Operating at 1.2V with CL22 timings, the sticks run at standard JEDEC voltage and have no heat spreaders attached. Power draw stays within base DDR4 limits during sustained workloads, and the bare PCB design relies on normal chassis airflow for cooling.

Questions about this item

Does the CL22 latency limit responsiveness when the workstation runs memory-heavy tasks for hours?

CL22 is the rated CAS latency at DDR4 3200; the modules operate at 1.20 V without a heat spreader, so sustained throughput stays at the rated speed.

How much heat or noise do the four 16 GB sticks add when the system runs all day?

The kit uses unbuffered non-ECC DDR4 UDIMMs at 1.20 V with no heat spreaders; they add no active cooling and produce no audible noise.

What must the Thinkmate GPX-WS-540X1 already have for this 288-pin DDR4 kit to work?

The workstation needs four free 288-pin DDR4 UDIMM slots that support non-ECC unbuffered memory at 1.20 V.
