Capacity and Compatibility

This 256GB kit provides sixteen 16GB DDR4 3200 modules built for ThinkMate GPX-PS4-12A1 GPU-optimised servers. It targets IT teams who need maximum registered ECC capacity in a single qualified configuration.

Build Integration

Each module is a 288-pin RDIMM running at 1.2V with CL22 latency and a 2Rx8 organisation. Registered buffering and ECC protect data integrity under sustained load, while the standard DDR4 voltage keeps power draw predictable for dense server chassis.

Upgrade Context

The kit replaces smaller or mixed-capacity DDR4 RDIMM sets to populate all slots with matched 16GB modules. The jump is worth it when workloads demand the full 256GB ceiling and qualified compatibility removes the risk of POST errors or throttling.

Questions about this item

What sustained load limit appears first when all 16 modules run at DDR4 3200 CL22?

The registered ECC design shifts the first bottleneck to the memory controller on the motherboard rather than the modules themselves.

How do the 1.20 V 2Rx8 modules behave for noise heat and power during continuous operation?

They run at standard DDR4 voltage with no heat spreaders so thermal output depends on chassis airflow and the server fan profile.

Which server must already be in place for this 256 GB kit to function?

It is validated for Thinkmate GPX-PS4-12A1-2GPU and GPX-PS4-12A1-4GPU GPU-optimised servers with 288-pin DDR4 RDIMM slots.
