NEMIX RAM
A single 32 GB DDR5 module running at 4800 MHz with ECC and 1.1 V operation for error-correcting server workloads
This is a 32GB DDR5 4800 ECC UDIMM module built for workstations and servers that require error-correcting unbuffered memory. It suits administrators upgrading a single slot or building a system with one DIMM per channel. Buyers who need registered or load-reduced DIMMs cannot use this module.
The module runs at 1.1V with CAS latency 40 and a 2Rx8 organisation, delivering stable throughput under continuous server workloads. Major OEM chips from Samsung, Micron or Hynix provide consistent signal integrity during extended duty cycles. Systems without DDR5 4800 support will not reach the rated speed.
The 288-pin UDIMM fits standard DDR5 slots and installs like any unbuffered DIMM. Common issues include mixing this ECC module with non-ECC memory or populating slots in an order the motherboard manual does not support. BIOS must be set to the correct voltage and speed for the module to post reliably.

The module operates at 1.1 V with DDR5 4800 speed and CAS 40 latency, which keeps power draw low during sustained workloads.
A DDR5‑compatible motherboard with a 288‑pin UDIMM slot and an integrated memory controller that supports ECC unbuffered modules is needed.
DDR5 modules negotiate speed with the memory controller; if the platform only supports lower DDR5 data rates, the kit will run at the highest mutually supported speed.
