GIGABYTE B650 AORUS Elite AX 64GB DDR5 kit

This 64GB kit contains four 16GB DDR5 UDIMM modules validated for the GIGABYTE B650 AORUS Elite AX motherboard. It targets builders who want a matched set that installs without manual tuning. Buyers needing ECC error correction or registered signal buffering should look elsewhere.

Four 288-pin slots at 1.10V

The modules are unbuffered non-ECC DDR5 running at 4800 MT/s with CL40 latency at the standard 1.10V. They occupy all four DIMM slots on the board, leaving no free sockets for later expansion. The kit requires a platform that supports DDR5 UDIMM at this speed and voltage.

Ready-to-install matched set

The package delivers the complete 64GB configuration in a single kit, eliminating the risk of mixing modules from different production runs. No heat spreaders are included, so airflow around the bare PCB is necessary. No additional software or firmware tools are bundled.

Questions about this item

Will 4800 MT/s CL40 at 1.1 V throttle under long workloads?

The modules run at the JEDEC-standard 4800 MT/s with CL40 latency and 1.1 V, so sustained throughput is limited to that rated speed.

How hot or loud do the bare sticks get during all-day operation?

There is no heat spreader, so the Samsung, Micron or Hynix DRAM relies on case airflow; power draw stays at the rated 1.1 V with no active cooling noise.

Does my Gigabyte B650 AORUS Elite AX need a BIOS update before installing this 4 × 16 GB kit?

The kit is validated for that motherboard; install the 288-pin UDIMMs in the four slots and the board will train at 4800 MT/s.
