Hi all. I recently started undervolting my CPU and here are my results.
Mobo: MSI MAG B550 Tomahawk Max WiFi
RAM: Kingston Fury Beast 3200 CL16 (overclocked to 3800 CL18)
Cooler: Be Quiet! Dark Rock 4
Thermal paste: Corsair TM30
Case: MSI MAG Forge 100M
Fans: CPU Cooler: Be Quiet! Silent Wings Pro 4 (1600 RPM max), 3 Arctic P12 PWM intake, 2 Arctic P14 PWM on top (exhaust) and 1 P12 as exhaust
Curve optimizer: -30 all cores
PBO: TDC and EDC on auto
Offset: +150
Manual voltage offset: 1.15V (!!!!)
At first I played with PBO (120W, 90A, 120A), the processor could sometimes boost to 5 GHz, but under prolonged loads it dropped the boost frequency to 4.2 – 4.3, the heating was up to 70-75 degrees.
To begin with, the result was very good, but I wanted a higher boost frequency, and I got it. Judging by the fact that my processor was able to take -30 in Curve Optimizer, I got a very good chip, and knowing this, I decided to try lowering the voltage manually. Three days of testing and I achieved the desired result.
In the idle state, the processor heats up to 37-32 degrees, under load up to 50-55 maximum (Benchmarks, games, etc), while the boost frequency is always kept at the maximum (5Ghz).

I didn’t notice any performance loss. Everything works stably.
