Hi, your 3900X tends to draw a lot of voltage during startup. Every time I power on the PC, I log into Windows and open Ryzen Master. The system reports high voltages—CPU-Z and Ryzen Master show values around 1.45V before I manually set it to 1.325V in Ryzen Master. Random blue screens appear during boot or when another profile isn’t selected. I attempted to cap the BIOS voltage at 1.2V but it didn’t help. My motherboard is an X570 AORUS MASTER (rev. 1.0). Could you assist in lowering the default voltage so it stays stable? Thanks ahead of time.

Ryzen shows an unusually strong idle voltage, typically between 1.42 and 1.45V. This is typical unless the device slows during heavy use.

It's odd then. Most folks warn against touching Ryzen OC, but I’ve got higher clocks with lower voltage using OC. I even achieved 4.2GHz on half the cores and 4.1GHz on the other at 1.15V, which doesn’t really add up since it boosts that much at 1.45V.

Yes, that's correct about Ryzen. All-core operations run at reduced power, while single cores operate at higher voltage levels.

Stock rises to 1.5V in a single core boost, which is typical. If BSOD appears, it's unusual.

However, I only experience a blue screen either immediately after powering on my PC or before I make any manual adjustments. After that, it rarely occurs again, so it might be related to the CPU. It seems like the issue could be connected to the 1.45+V setting across all cores during startup. Location Slovakia: cauko

That's quite a bit for an all-core workout.

I thought about it too. It seems my manual setup only kicks in once Ryzen Master starts and the OC is done. Until then, the CPU was using that amount of power. I checked the BIOS settings but maybe I misapplied them. It’s not working as expected.

Varied results are expected. Testing the 95 smallest FFT values might not reach close to 1.4V using automatic adjustments.

It won't work, but I feel uneasy about operating above 1.45V. Those peak voltages occur in idle mode, during rapid click bench testing it was roughly 1.35 to 1.36 at 4.2Ghz across all cores, which aren't even reliable. I can achieve 4.2Ghz clocks at 1.2V using manual overclocking.
