 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!
 
-## Introduction
+# Introduction
 
 The SiFive U74 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.
 
 Warning: You are responsible for the safety of your board.

 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).
