NEMIX RAM
32 GB DDR5 4800 ECC registered DIMM with CL40 latency and 1.1 V operation
This 32GB DDR5 4800 registered DIMM provides error-correcting memory for compatible Hynix server and workstation platforms. It operates at 1.1V with a CL40 latency and a 2Rx4 organisation. The module uses a standard 288-pin DDR5 form factor without a heat spreader.
Buyers needing non-ECC unbuffered memory for consumer desktops or laptops should look elsewhere. Systems that do not support registered ECC DDR5 modules cannot use this part.
Only motherboards with DDR5 RDIMM slots that accept registered ECC modules at 4800 MT/s can install this memory. Verify the platform qualified-vendor list before purchase.

No firmware updates or reseating are needed; the registered ECC DDR5 modules are validated for Hynix platforms and operate at the standard 1.1 V without further intervention.
The module has no heat spreader, so the DRAM junction temperature reaches its JEDEC limit before any other constraint, relying on chassis airflow to stay within spec.
At 1.1 V the stick draws only a few watts and is completely silent; all audible noise comes from the server fans that cool the memory slots.
