System-Specific Upgrade

This 64GB DDR4 3200 ECC RDIMM is built for ThinkMate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations. IT professionals and system integrators use it to expand memory capacity in these qualified platforms. The module is validated for registered server environments requiring error-correcting code.

4Rx4 Rank Configuration

The single rank specification that determines compatibility is the 4Rx4 organisation. This module uses a quad-rank x4 layout that must match the workstation memory controller requirements. Installing a different rank structure will prevent the system from recognising the memory or cause instability.

Installation Notes

The 288-pin DDR4 RDIMM installs in standard DIMM slots using 1.20V power. No heat spreader is fitted, so airflow across the module is required. Common issues include mixing registered and unbuffered DIMMs or populating slots in an order the platform firmware does not support.

Questions about this item

What does the 3200 MT/s rating mean once the module is installed in a ThinkMate workstation?

The module runs at DDR4 3200 (PC4-25600) speed, delivering 25 600 MB/s of theoretical bandwidth when the platform operates at its rated frequency.

How does the registered ECC interface affect what the memory controller can do?

Registered ECC RDIMM adds a register between the DRAM and the memory controller, allowing higher capacity per channel while providing single-bit error correction and multi-bit error detection.

Will the 288-pin RDIMM fit the memory slots in a GPX-WS-540RTP, GPX-WS-740RTP or GPX-WS-760S1?

Yes, the 288-pin DDR4 RDIMM form factor matches the DIMM slots in those ThinkMate workstations, and the module is validated for those specific models.
