Installing An Expansion Card; Back Panel Connectors - Gigabyte Z590I AORUS ULTRA User Manual

Dual Channel Memory Configuration
This motherboard provides two memory sockets and supports Dual Channel Technology. After the memory
is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual
Channel memory mode will double the original memory bandwidth.
The two memory sockets are divided into two channels and each channel has one memory socket as following:
Channel A: DDR4_A1
Channel B: DDR4_B1
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one memory module is installed.
2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of
the same capacity, brand, speed, and chips be used.
