What it means
"Undervolting an AMD system" is really two different jobs with very different difficulty and risk: lowering voltage on your Radeon GPU, and lowering it on your Ryzen CPU. They use different tools, and which one you should reach for first is not a coin flip — start with the GPU.
More detail
The Radeon GPU side is the friendly one: you do it inside AMD's Adrenalin software in Windows (Performance → Tuning), it is fully reversible with a reset button, and a careful undervolt tends to mean a cooler, quieter card at the same or even slightly better performance — this is the path Compy actually walks you through (see the AMD GPU undervolt guide). The Ryzen CPU side is advanced and genuinely risky: it lives in the BIOS as Precision Boost Overdrive / Curve Optimizer, and pushing the offsets too far causes crashes that look 'random' for weeks before you trace them back — so it is small steps, hours of stability testing, and a known-good fallback (loading BIOS defaults undoes it). …
