ThinkMate Workstation ECC Upgrade

This 256GB kit supplies four 64GB DDR4 3200 registered DIMMs built for ThinkMate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations. ECC and registered buffering protect data integrity in multi-threaded server workloads. The modules run at 1.2V with CL22 timing and use a 4Rx4 organisation on 288-pin RDIMM form factor.

Sustained Load Stability

Each module is stress tested under load before shipping to verify reliable operation during extended compute tasks. Registered signalling reduces electrical load on the memory controller, helping maintain consistent throughput when all 256GB are populated. The 1.2V operating voltage keeps power draw predictable during long rendering or virtualization sessions.

Pre-Installation Checklist

Confirm your workstation model matches the GPX-WS-540RTP, GPX-WS-740RTP or GPX-WS-760S1 series before ordering. Verify the motherboard has four free 288-pin DDR4 RDIMM slots and supports 4Rx4 registered ECC modules at 3200MHz. Consult the system manual for approved population rules and maximum supported capacity per channel.

Questions about this item

How much power will the 3200 MHz 1.2 V registered kit draw when the workstation runs continuously?

Each 64 GB module operates at 1.20 V; the kit contains four modules and runs at the standard DDR4 3200 voltage, so power scales with the 256 GB total capacity under load.

What must the workstation already provide for these modules to function?

The system needs four free 288-pin DDR4 RDIMM slots that support ECC registered memory and accept 4Rx4 modules at CL22 timing.

Will this kit work in a Thinkmate GPX-WS-540RTP alongside any factory memory already installed?

The kit is validated for the GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1; mixing with existing memory requires matching speed, voltage, rank and ECC type on the same channel.
