Undervolt Your CPU for Max Mining Efficiency (2025 Guide)
Want to reduce power usage and boost efficiency while CPU mining in 2025? In this video, I’ll show you how to undervolt your CPU for crypto mining using the exact BIOS settings, PBO limits, and power draw targets I use to maximize hashrate and cut electricity costs.
Whether you’re mining Monero (XMR), Warthog, or any RandomX-based coin, these undervolt settings will help you improve stability, reduce heat, and make your mining rig more profitable.
🧠 Works for most modern Ryzen CPUs — tested on the Ryzen 7950X with an ASUS B650M motherboard running HiveOS.
This is the best CPU undervolting guide for mining in 2025, especially if you want to build a low-power, high-efficiency rig for home crypto mining.
