NEMIX RAM
Six 32 GB DDR5 4800 ECC registered DIMMs deliver 192 GB at CL40 and 1.1 V for Thinkmate RAX‑QE12 servers
This kit provides 192GB of DDR5 ECC registered memory in six 32GB modules. It is built for the THINKMATE RAX-QE12 rackmount server and runs at 4800MHz with CL40 latency at 1.10V.
IT teams running virtualisation, databases or heavy compute workloads on the qualified THINKMATE platform will benefit from the capacity and error correction. Builders using consumer motherboards, non‑qualified servers or systems that require unbuffered DIMMs should look elsewhere.
The 288‑pin RDIMMs seat like standard server memory; align the key notch and press until the latches click. Common issues include mixing ranks or speeds across channels, skipping the vendor‑specified population order, or forgetting to enable ECC in BIOS.

Yes, the modules are 288-pin DDR5 RDIMMs built for the THINKMATE RAX-QE12; the platform must provide registered DDR5 slots to accept them.
The server can run mixed kits if every module is DDR5 ECC registered at 1.1 V, but matching speed, rank and latency across all slots avoids timing fallbacks.
Check the BIOS memory information or an OS tool such as dmidecode; it should show 4800 MT/s, CAS 40, 1.1 V and registered ECC on all six modules.
