64GB DDR4 ECC RDIMM kit

This kit provides 64GB of DDR4 3200 memory in four 16GB registered DIMMs. It is built for THINKMATE GPX workstations that require ECC protection and registered signalling for data-integrity workloads.

Fits four 288-pin DDR4 slots

The modules occupy four DIMM slots and run at 1.2V with CL22 timing. Registered buffering reduces electrical load on the memory controller, leaving headroom for large-capacity configurations in compatible THINKMATE GPX-WS-540RTP, GPX-WS-740RTP or GPX-WS-760S1 systems.

Passive operation at standard voltage

Without heat spreaders the sticks rely on chassis airflow and the 1.2V supply keeps power draw low. Registered ECC modules typically run cooler than high-frequency unbuffered kits, so acoustic impact is minimal in a properly ventilated workstation.

Questions about this item

How does the CL22 latency behave during continuous workloads?

The CAS latency is fixed at CL22 and does not change under sustained use.

What is the power draw of the 64GB kit running all day?

Each module operates at 1.20V, so the four 16GB sticks draw minimal power continuously.

Which Thinkmate workstations must I already own for this memory to work?

This kit is validated for GPX-WS-540RTP, GPX-WS-740RTP and GPX-WS-760S1 systems.
