Apply a [patch](/posts_media/2023-10-21-overclocking-starfive-vf2/overclock_vf2.patch) to JH7110_VisionFive2_upstream branch of [starfive-tech/linux](https://github.com/starfive-tech/linux). `make -j4; make modules_install; make install; make dtbs_install`. Edit /boot/uEnv.txt `fdtfile` with a proper devicetree path. Profit!
StarFive VisionFive 2 is a second generation of RISC-V boards from StarFive, which is based on StarFive JH7110 SoC with 4 of SiFive's U74 cores.
The SiFive U74 max frequency in StarFive JH7110 is 1.5 GHz by default, but it can work much better, because even under load the temperature never exceeds 50ºC, so overclocking is worth it. The JH110 can be overclocked to 1.8 GHz, which will be done in this article.
After you successfully overclocked your VF2, you can ask yourself a question - "can it do better?". [No, it can't](http://forum.rvspace.org/t/how-do-you-overclock-the-vf2/2920/5).
