Capacity and Compatibility

This kit provides 1TB of DDR4 memory across sixteen 64GB registered DIMMs. It is built for ThinkMate GPX-PS4-12A1 GPU-optimised servers that require ECC registered modules. The 4Rx4 organisation and CL22 latency suit dense multi-socket configurations. Buyers needing consumer desktop memory or unbuffered modules should look elsewhere.

DDR4 3200 Interface Limits

The modules run at 3200 MT/s (PC4-25600) at 1.2V on a 288-pin bus. Registered signalling adds one cycle of command delay, so maximum throughput depends on the server memory controller and populated slot count. Populating all channels at this capacity may force the controller to drop below the rated data rate. Systems limited to lower DDR4 speeds will clock the kit down automatically.

Upgrade Context

This kit replaces smaller-capacity RDIMM sets or mixed-rank configurations that limit total addressable memory. The jump is worthwhile when workloads exceed the current memory ceiling and the platform qualifies 4Rx4 modules at 3200 MT/s. Servers that only support 1Rx4 or 2Rx4 ranks cannot use these DIMMs.

Questions about this item

Should I choose the 16-module kit or a smaller capacity for my ThinkMate GPX-PS4 server?

The 16 x 64 GB kit fills all available slots on the ThinkMate GPX-PS4-12A1-2GPU and GPX-PS4-12A1-4GPU platforms, delivering the full 1 TB maximum memory the chassis supports.

What does the DDR4 3200 CL22 rating mean once the modules are installed in the GPU-optimised server?

At 3200 MT/s with CL22 timing the registered ECC DIMMs provide the bandwidth and error correction the GPX-PS4 platform expects for sustained multi-GPU workloads.

How does the 288-pin RDIMM interface and 4Rx4 organisation affect compatibility with the ThinkMate GPX-PS4 series?

The 288-pin DDR4 RDIMM form factor and 4Rx4 rank structure match the GPX-PS4 memory controller requirements, ensuring the modules are recognised and run at the rated 1.20 V.
