NEMIX RAM 64GB (2×32GB) DDR5 4800 CL40 1.10V 2Rx8 288-pin UDIMM for GIGABYTE B650I AORUS Ultra

Kit capacity and platform match

This 64 GB kit provides two 32 GB DDR5 modules built for the GIGABYTE B650I AORUS Ultra Mini-ITX motherboard. It targets builders who need the full dual-channel capacity that board supports without mixing densities. Buyers who require ECC error correction or registered buffering should look elsewhere.

Speed and timing gate

The modules run at DDR5 4800 with CL40 latency at 1.10 V, matching the PC5-38400 specification. That speed and timing combination is the single figure that decides whether the kit will POST and run stable on the target platform. Systems needing higher frequencies or lower latencies will not be satisfied by this part.

Sustained-load behaviour

Unbuffered non-ECC UDIMMs with a 2Rx8 organisation deliver consistent throughput during long workloads because they lack the extra buffering step that adds latency under pressure. The 1.10 V operating voltage keeps thermals modest even when all 64 GB are fully utilised for extended periods. No heat spreader is fitted, so case airflow handles the thermal load directly.
