NEMIX RAM 128GB DDR5 6400 CL52 1.1V 2Rx4 ECC Registered RDIMM memory upgrade

Exact-match DDR5 server upgrade

This 128GB DDR5-6400 RDIMM delivers PC5-51200 speed at CL52 latency with a 1.1V operating voltage. It is built as a 2Rx4 registered ECC module using major OEM DRAM from Samsung, Micron or Hynix. The kit targets administrators upgrading ASRock Rack GNRD16DNO or GNRD16QM3-NL motherboards where the memory controller expects this precise rank, voltage and timing configuration.

Registered ECC build for full population

The 288-pin RDIMM form factor uses a registered architecture that buffers address and command signals, allowing every slot to run fully populated at rated capacity without overloading the memory controller. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. No heat spreader is fitted, so airflow clearance follows the motherboard's standard DIMM spacing rules.

Verify population rules before ordering

Server and motherboard memory support varies by model, so consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps. This module will not fit boards that require UDIMM or SODIMM form factors, nor will it operate on platforms limited to lower DDR5 speeds or different voltage requirements. Buyers needing non-ECC unbuffered memory or a different capacity per module should look elsewhere.
