NEMIX RAM
64 GB DDR5 registered ECC RDIMM running at 4800 MT/s with CL40 latency for Supermicro servers
This 64GB registered DDR5 module operates at 4800MT/s with CL40 latency and 1.10V voltage. It uses a 2Rx4 rank configuration built with major OEM chips and carries ECC error correction. The 288-pin RDIMM form factor fits compatible Supermicro server and workstation motherboards requiring registered memory.
This module targets administrators expanding memory in qualified Supermicro servers or workstations that support DDR5 4800 registered ECC RDIMMs. It is not for desktop PCs, laptops or consumer motherboards that accept only unbuffered non-ECC DIMMs. Buyers needing unregistered memory or different speeds should verify their platform documentation before purchasing.
The single specification that determines fit is the registered ECC RDIMM design combined with DDR5 4800 signalling. Only systems explicitly qualified for this module type and speed will recognise and stabilise the 64GB capacity. Confirm the motherboard memory qualification list matches this exact configuration to avoid boot or stability issues.

Yes, the module uses the standard 288-pin DDR5 RDIMM form factor designed for Supermicro server motherboards that support registered ECC memory.
Align the notch with the slot key, press straight down until both side clips click shut, then verify the system BIOS reports 64 GB at 4800 MT/s with ECC active.
Replace only if the system logs report uncorrectable ECC errors or the module fails POST; otherwise it is rated for continuous operation at 1.1 V.
