128GB DDR4 ECC RDIMM Kit

This 128GB kit comprises four 32GB DDR4 3200 modules built for the ThinkMate GPX-XS8-14S3-4GPU workstation. Registered ECC RDIMM design targets servers and workstations that require error correction and signal integrity under sustained loads.

Registered 288-Pin Modules at 1.2V

Each module uses a 288-pin RDIMM form factor with a 2Rx8 organisation and operates at 1.2V without a heat spreader. Registered buffering reduces electrical load on the memory controller, allowing the four-module population supported by the qualified platform.

DDR4 3200 CL22 Platform Limit

The memory runs at DDR4 3200 (PC4-25600) with a CAS latency of 22, matching the workstation's validated speed grade. Systems that cannot accept registered ECC RDIMMs or that cap memory speed below 3200 will not support this kit.

Questions about this item

What does the DDR4 3200 PC4-25600 interface cap the bandwidth at for this kit?

The DDR4 3200 PC4-25600 specification provides up to 25600 MB/s theoretical bandwidth per module, with four 32GB modules installed.

What physical slot and pin count does this 288-pin RDIMM kit require?

Each 32GB module uses a 288-pin DDR4 RDIMM form factor and fits standard server DIMM slots on the ThinkMate GPX-XS8-14S3-4GPU workstation.

How are the four 2Rx8 registered ECC modules installed, and what step is often missed?

Install all four 32GB sticks in the correct channel order shown in the workstation manual; the step often missed is populating every slot in the prescribed sequence for quad-channel operation.
