NEMIX RAM
128 GB of DDR5 ECC registered memory in four 32 GB modules running at 4800 MT/s with CL40 latency for ThinkMate nearline storage servers
This NEMIX RAM kit provides 128GB of DDR5 memory across four 32GB registered DIMMs. It operates at 4800MHz with CL40 latency and 1.1V voltage. The modules feature ECC error correction and 2Rx8 organization for server-grade reliability.
This memory is validated for the ThinkMate STX-NL-QE16 E4 platform and similar enterprise systems requiring registered ECC DDR5. It is not suitable for consumer motherboards that only accept unbuffered non-ECC modules or for any system that cannot use 288-pin RDIMMs.
The registered ECC design with 2Rx8 rank configuration determines compatibility with server chipsets that require buffered memory. Systems needing unbuffered UDIMMs or different rank structures cannot use this kit.

Yes, the 128GB kit is built for the THINKMATE STX-NL-QE16 E4 nearline storage server and needs a motherboard that accepts 288-pin DDR5 registered DIMMs running at 1.10V.
The kit uses 2Rx8 organisation; mixing ranks is possible only if the server's memory controller and BIOS support mixed-rank populations — check the system manual before installing.
Enter the server BIOS or UEFI and verify that all four 32GB modules appear at 4800 MT/s with CL40 timing and that ECC status shows enabled for each channel.
