Compatible with Thinkmate GPX-XS8-14S3-4GPU

This 128 GB kit is built for the Thinkmate GPX-XS8-14S3-4GPU workstation. It delivers registered ECC DDR4 memory for servers and workstations that require error correction and signal buffering. The two 64 GB modules install directly into 288-pin DDR4 slots. System integrators and IT professionals gain a validated upgrade path for this specific platform.

Registered ECC RDIMM with 4Rx4 organisation

Each module uses a 4Rx4 rank structure and operates at 1.20 V with a CL22 latency. The registered design reduces electrical load on the memory controller, supporting stable operation in multi-DIMM configurations. No heat spreader is fitted, so airflow across the bare PCB must be provided by the chassis. The 288-pin RDIMM form factor matches standard DDR4 server sockets.

Two-module kit tested under load

The package contains two 64 GB RDIMMs pre-configured as a matched 128 GB set. Modules are stress tested under load before shipment to verify reliability in mission-critical environments. Major OEM DRAM from Samsung, Micron or Hynix is used depending on supply. Lifetime replacement coverage is provided by the manufacturer.

Questions about this item

What DDR4 speed and PC4 rating does this kit run at?

The modules are rated DDR4 3200 (PC4 25600), so the memory bus tops out at 3200 MT/s in compatible systems.

Will these 288-pin RDIMMs fit in my ThinkMate workstation's DIMM slots?

Yes — each stick is a standard 288-pin DDR4 RDIMM, matching the slot layout of the ThinkMate GPX-XS8-14S3-4GPU workstation.

How do I install the two 64 GB modules, and what step is often missed?

Power off the system, open the chassis, align each module's notch with the slot key, press firmly until both side clips click, then verify in BIOS that all 128 GB are recognised.
