NEMIX RAM
96 GB kit of twelve 8 GB DDR4-3200 ECC registered DIMMs for ThinkMate HDX-XN servers
This 12-module kit delivers 96GB of DDR4 3200 registered ECC memory built for ThinkMate HDX-XN servers. Each 8GB stick runs at 1.2V with CL22 latency and a 1Rx8 organisation. The registered design adds stability for multi-socket workloads that demand error correction.
Swapping a partial population for this matched 12x8GB set removes rank-mismatch penalties and lets the memory controller run all channels at the rated 3200MT/s. The jump is worth it when the server currently runs below 96GB or mixes speeds that force the whole subsystem down to a lower data rate.
Modules seat in the 288-pin DDR4 slots like any RDIMM; the kit arrives pre-sorted so no manual matching is required. Common issues are forgetting to enable ECC in BIOS, leaving empty slots between populated channels, or skipping the firmware update that unlocks full 3200 operation on older ThinkMate HDX-XN revisions.

Yes, each 8 GB module is a 288-pin DDR4 RDIMM, the standard form factor for the ThinkMate HDX-XN series listed in the compatibility data.
Follow the ThinkMate HDX-XN owner's manual for the exact channel population sequence; installing all 12 modules in the wrong order can prevent the system from recognising the full 96 GB capacity.
No firmware or battery maintenance is needed for the ECC RDIMMs themselves; only a failed module would require replacement under the lifetime warranty.
