Ryzen CPU overclock
Ryzen CPU overclock
The increased voltage is probably an initial input for the regulators that generate the actual 1.2 volts. From the 12V supply through the VRM to the motherboard, it reduces to 1.8V before reaching the memory controller, adjusting its output according to workload and configuration requirements.
You may consider reducing the overclock to a more consistent system by adjusting the RAM tab voltage. Since it's set to auto, try manually setting it below 1.8 volts. After applying the changes and restarting, ensure the voltages match your RAM's capabilities.
Eximo:
The higher voltage probably comes from an input voltage to the regulators that generate 1.2 volts.
12V from the PSU goes to the motherboard VRM, then down to 1.8v and finally to the memory controller, which adjusts it as needed for workload and settings.
I wondered if this is just a false reading or name in HWMonitor.

My concern is whether it's acceptable for the CPU to downclock and boost above or below the frequency set in BIOS.
if the power saving setting is active, it will reduce the clock speed when not under heavy use.
if the power saving feature is activated it will reduce clock speed when not under heavy use.
You're referring to AMD Cool'n'Quiet, right?
Yes, it's enabled but it didn't adjust speed/boost before because the vcore was set in UEFI to 1.275.
it is an option that allows lowering the cpu clock when applying oc, which can decrease core speed if it isn't in use.
it is an option to lower the cpu clock when applying oc which can reduce core speed if not used. Ok, ok. I think downclocking and boosting after oc is just normal behavior with ryzen cpus, and everything is safe (correct me if i'm wrong). Thanks for the answers from everyone.
