NEMIX RAM
Four-module 32 GB DDR4 ECC registered kit at 3200 MT/s CL22, 1.2 V, 288-pin RDIMM for ThinkMate GPU servers
This 32 GB kit contains four 8 GB DDR4 3200 ECC RDIMM modules built for ThinkMate GPX-PS4-12A1 servers. Registered buffering and error correction protect data integrity in GPU-optimised workloads. The CL22 latency and 1.20 V operation suit the platform specifications. IT teams use this configuration to expand capacity in multi-GPU deployments.
Confirm the server has at least four free 288-pin DDR4 RDIMM slots before ordering. Check the system manual for supported ranks per channel and maximum capacity per socket. The modules are single-rank 1Rx8 parts, so population order matters for performance. Ensure the BIOS is current to recognise the full 32 GB at 3200 MT/s.
This kit upgrades systems running lower-capacity DDR4 ECC RDIMMs or slower speed grades. The jump is worthwhile when workloads exceed current memory headroom or when adding GPUs increases buffer demands. Do not mix with unbuffered UDIMMs or different voltage modules; registered ECC is required.
