Designed for Thinkmate GPX-WS-540X1 workstations

This NEMIX RAM kit delivers 64GB of DDR4 memory across eight 8GB unbuffered UDIMM modules. It targets IT professionals and system integrators who need a validated upgrade for this specific Thinkmate platform. The modules operate at 1.20V and carry a CL22 latency rating.

DDR4 3200 bandwidth caps at PC4-25600 transfer rates

The DDR4 3200 interface limits peak throughput to 25600 MB/s regardless of module count. Unbuffered non-ECC operation means the memory controller handles all address and command signalling directly. Eight single-rank 1Rx8 modules populate every slot on many workstation boards, leaving no room for further expansion.

Verify eight free 288-pin slots

Confirm the workstation has eight available UDIMM sockets and that its memory controller accepts 3200 MT/s non-ECC modules at 1.20V. The kit requires a platform qualified for PC4-25600 speeds and 1Rx8 organisation. Systems limited to lower speeds or registered memory will not boot with this configuration.

Questions about this item

Should I buy the 64GB kit or a smaller capacity for my THINKMATE GPX-WS-540X1?

The 64GB kit provides eight 8GB modules that fill all available slots on the THINKMATE GPX-WS-540X1 workstation. Choose this kit when you need the maximum supported capacity; select a smaller kit only if your workloads use less memory and you want to leave slots open for future expansion.

What does the 3200 speed rating deliver in actual use?

The DDR4 3200 (PC4-25600) modules run at 3200 MT/s with CL22 latency at 1.20V. In the THINKMATE GPX-WS-540X1 they provide the rated bandwidth for multi-threaded workloads, virtualisation and large datasets, limited by the platform's memory controller.

How does the 288-pin DDR4 UDIMM interface limit performance?

The 288-pin unbuffered DDR4 interface caps transfer rate at 3200 MT/s and does not support ECC or registered signalling. The workstation's memory controller determines the final operating speed, which cannot exceed the DDR4 UDIMM standard.
