Designed for Thinkmate GPU servers

This 128 GB kit contains two 64 GB DDR4 3200 MHz registered ECC RDIMMs built for Thinkmate GPX-PS4-12A1-2GPU and GPX-PS4-12A1-4GPU systems. The modules run at 1.2 V with CL22 latency and use a 4Rx4 organisation. They are intended for enterprise workloads that require error correction and registered signalling.

Verify slot count and qualified vendor list

Before ordering, confirm that your Thinkmate server has enough free 288-pin RDIMM slots for a two-module kit. Check the system documentation or vendor qualified list to ensure 64 GB 4Rx4 modules are supported at the desired speed. Registered ECC memory must be matched to the platform memory controller and BIOS revision.

Kit delivers matched pair for dual-channel operation

The package supplies two identical modules tested together, allowing dual-channel population without mixing ranks or speeds. No heat spreaders are included, so airflow in the server chassis must be sufficient for bare modules. The kit contains only the memory; no additional software, cables or tools are provided.

Questions about this item

Does the kit include only the two 64 GB RDIMM modules or are any cables or tools supplied?

The package contains exactly the two 64 GB DDR4 3200 MHz CL22 ECC registered RDIMM modules; no cables, brackets or tools are included.

Should I pick the 128 GB (2×64 GB) kit or a smaller capacity for my Thinkmate GPX-PS4 server?

Choose the 128 GB kit when your workload needs the full 128 GB across two slots; select a smaller kit only if your application fits in less memory and you want to leave slots free for future expansion.

What does the 3200 MHz PC4-25600 rating mean once the modules are installed in the server?

The modules will run at 3200 MHz with CL22 latency at 1.20 V, delivering the rated PC4-25600 bandwidth provided the Thinkmate platform supports DDR4 3200 registered ECC memory.
