Capacity & Compatibility

This 512 GB kit contains four 128 GB DDR4 3200 ECC RDIMM modules built for THINKMATE GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations. Registered 4Rx4 organisation and 1.20 V operation suit enterprise workloads that demand data integrity and maximum density. Buyers needing non-ECC memory or consumer desktop support should look elsewhere.

Platform Verification

Confirm the workstation model matches one of the three listed part numbers before ordering. The motherboard must accept 288-pin DDR4 RDIMMs and support 4Rx4 registered modules at PC4-25600 speed. Systems limited to UDIMM, lower rank counts or slower JEDEC profiles will not recognise this kit.

Thermals & Power

Modules run at standard 1.20 V without heat spreaders, relying on chassis airflow for cooling. Typical power draw per module stays low under sustained server loads, and the registered buffer adds negligible latency. Acoustic impact is limited to the system fans already present in the workstation enclosure.
