Welcome to the discussions! Most B and X series boards allow undervolting, while A series boards usually don’t. PBO isn’t permitted on A series boards. Some exceptions might exist for certain boards or BIOS versions with full voltage control, but generally the A320 and A520 models are quite restricted. You won’t find Curve Optimizer support for Ryzen 5000 series CPUs, since it’s part of PBO.
The software will prevent access to all settings if an A-series board is detected. It is designed solely for monitoring in that scenario.
