NEMIX RAM
An 8 GB DDR4 3200 ECC registered DIMM with CL22 timing and 1.2 V operation for compatible server and workstation motherboards
This NEMIX RAM module delivers 8 GB of registered DDR4 memory rated at 3200 MT/s with CL22 latency. It operates at 1.20 V and uses a 1Rx8 organisation on a 288-pin form factor. The part is built for compatibility with Hynix server and workstation platforms.
Registered buffering and on-die ECC protect data integrity during continuous operation in multi-socket servers. Stress testing under load validates stability for virtualisation, database and NAS workloads where uninterrupted uptime is required.
The module is a registered ECC RDIMM, so it will only function in motherboards that explicitly support registered memory; it cannot be used in consumer desktop or laptop boards that accept only unbuffered DIMMs.

The module operates at 1.20 V with CL22 timings, a voltage level typical for DDR4 server memory that keeps power draw and heat low during continuous workloads.
Your motherboard must provide a 288-pin DDR4 RDIMM slot and a memory controller that supports registered ECC modules; standard consumer boards without ECC support will not work.
Yes, the module is built to match the Hynix HMA81GR7CJR8N-XN specification — same 3200 MT/s speed, CL22 latency, 1.20 V voltage and 1Rx8 organisation — so it will run in lockstep with existing sticks.
