Capacity and configuration

This kit supplies 64GB of DDR4 memory in two 32GB registered DIMMs. It is built for Thinkmate GPX workstations that require ECC RDIMM modules and will not fit systems limited to unbuffered UDIMMs.

Speed and headroom

Rated at DDR4 3200 with CL22 timing, the modules deliver PC4-25600 bandwidth for multi-threaded workloads and large datasets. Capacity stops at 64GB, so workloads that need more memory per channel will require a platform with additional slots.

Thermals and power

Operating at 1.20V without heat spreaders, the RDIMMs rely on chassis airflow for cooling. Registered buffering adds minimal latency overhead while keeping power draw low during sustained server and workstation tasks.

Questions about this item

Will these 3200 CL22 ECC RDIMMs work in a ThinkMate GPX-WS-540RTP alongside existing DDR4 modules?

The kit is validated for the GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1. Mixing speeds or ranks can force the system to run at the lowest common speed. For best stability, populate all slots with identical modules.

How can I verify the 64 GB kit is running at 3200 MT/s with ECC active after installation?

Enter the BIOS or UEFI and confirm the memory frequency shows 3200 MT/s and ECC is enabled. In the OS, use a tool such as dmidecode on Linux or CPU-Z on Windows to verify speed, CL22 timings and ECC status.

Does the package include only the two 32 GB RDIMMs or are any brackets or cables supplied?

The box contains the two 32 GB 288-pin DDR4 ECC RDIMMs only. No heat spreaders, brackets, cables or additional accessories are included.
