One of my favorite ROMs, The People’s ROM for Sprint Galaxy S3 SPH-L710, just got better with addition of multi-window, overclocking, and some more.
Want a very solid and stable custom ROM that runs better than your stock ROM with 1.836Ghz overclocking support?
If so, give TuchMi S3X ROM a try, this ROM is exactly that. For overclocking, google “setcpu” and download the app from XDA forums or use the on-board CPU app by typing “su” and “cpu” in terminal emulator. This ROM also comes V6 supercharger script, which can enhance and optimize your ROM even further.
Looking for a custom ROM that gives you performance? Well, FoxHound ROM has been known traditionally for great overclocking and performance with the Galaxy S2, now it’s also available for your Galaxy S3 GT-i9300, giving you up to 1.8Ghz of overclocking. In daily usage, I was able to get stable 1.7Ghz overclocking and near 6500-7000 in Quadrant benchmarking scores.
