Capacity and configuration

This 256 GB kit contains two 128 GB DDR4 RDIMMs that operate at 3200 MT/s with CL22 timings at 1.20 V. The modules are ECC registered and built with 4Rx4 organisation for high-density server workloads. They are validated for Thinkmate GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 workstations.

Workload headroom and limits

The 256 GB total capacity supports large in-memory databases, virtualisation hosts and scientific computing tasks that demand extensive address space. Registered signalling and ECC protect data integrity under sustained load. The CL22 latency and DDR4 3200 bandwidth set the ceiling for memory-bound throughput.

Thermals and power profile

Running at the standard 1.20 V DDR4 voltage keeps power draw predictable in multi-DIMM configurations. The modules ship without heat spreaders, relying on chassis airflow for cooling in dense server enclosures. Registered buffering adds minimal latency while maintaining signal integrity across full populations.

Questions about this item

How does this 256GB (2x128GB) DDR4 3200 CL22 ECC RDIMM kit behave alongside existing DDR4 ECC RDIMMs in a Thinkmate workstation?

When mixed with other DDR4 ECC RDIMMs the system will run all modules at the lowest common speed and highest latency; this kit is rated 3200MHz CL22 at 1.2V so it will down-clock automatically if older modules are slower.

How can I verify the kit is running at 3200MHz CL22 after installation?

Check the memory speed and timings in BIOS or UEFI, or use a tool such as CPU-Z or dmidecode; you should see 3200MT/s and CL22 for each 128GB module.

What is included in the box and what must be purchased separately?

The box contains two 128GB 288-pin DDR4 ECC RDIMM modules (total 256GB); no heat spreaders, cables, tools or additional hardware are included.
