128 GB DDR4 ECC RDIMM for ThinkMate

This 128 GB registered DDR4 module is built for the ThinkMate GPX-QN6-42E2-8NVLINK GPU-optimised server. It delivers ECC error correction and registered buffering for stable operation under sustained workloads. The single stick format suits high-density configurations.

DDR4 3200 PC4-25600 CL22 4Rx4 registered limits

The module runs at 3200 MT/s with a CAS latency of 22 cycles and a 4Rx4 organisation. Registered signalling adds one clock cycle of address latency compared with unbuffered DIMMs. The 1.2 V operating voltage is fixed by the DDR4 standard for this speed grade. 4Rx4 density may restrict the maximum number of modules per memory channel.

Check ThinkMate GPX-QN6-42E2-8NVLINK memory rules

Verify the server's qualified vendor list for 128 GB 4Rx4 RDIMM support and the maximum capacity per channel. Confirm the BIOS revision recognises this part number and that the CPU memory controller accepts 4Rx4 ranks at 3200 MT/s. Ensure the chassis has a free 288-pin DDR4 slot with registered DIMM keying.

Questions about this item

Should I choose the single 128GB module or look for multiple smaller modules for my ThinkMate server?

This listing is a single 128GB 4Rx4 RDIMM; using one module fills one slot and leaves others open for future expansion, while multiple smaller modules would occupy more slots immediately.

What does the 3200 MT/s rating mean for my ThinkMate GPX-QN6-42E2-8NVLINK server workloads?

The DDR4 3200 speed sets the maximum data rate the memory controller can use; real-world throughput depends on the platform's memory controller and the number of channels populated.

How does the 288-pin DDR4 RDIMM interface affect compatibility with my ThinkMate system?

The 288-pin RDIMM form factor and registered signal buffering are required by the ThinkMate GPX-QN6-42E2-8NVLINK; the module will not fit or function in systems that need UDIMM or a different pin count.
