ThinkMate-Compatible DDR4 ECC RDIMM Kit

This 64 GB kit contains four 16 GB DDR4-3200 registered DIMMs built for ThinkMate GPU-optimised servers. Each module runs at 1.2 V with CL22 latency and uses a 2Rx8 organisation. The memory is validated for the GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU platforms.

Registered ECC with 2Rx8 organisation

Error-correcting code and registered signalling protect data integrity under sustained multi-GPU workloads. The dual-rank x8 layout matches the server’s memory-controller requirements. Systems that need unbuffered non-ECC UDIMMs or a different rank configuration cannot use this kit.

Tool-free slot installation

Align the 288-pin edge connector with the motherboard key and press until the retention clips engage. Populate all four channels identically to maintain balanced bandwidth. Mixing ranks or speeds across channels will prevent the server from posting.

Questions about this item

What does the 3200 MT/s rating mean when the modules are installed in a Thinkmate server?

The DDR4 3200 (PC4-25600) rating sets the maximum data rate the modules can sustain; the server's memory controller will run them at that speed or the highest supported speed below it.

How does the 288-pin RDIMM interface and registered design affect compatibility?

The 288-pin RDIMM form factor with registered signalling is required by Thinkmate GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU platforms; unbuffered UDIMMs will not work.

What physical clearance is needed for the four 16 GB sticks in the server chassis?

Each module is a standard-height 288-pin DDR4 RDIMM without a heat spreader, so they fit in any Thinkmate slot that accepts full-height registered DIMMs.
