Board Software
ASUS has always had a great software package bundled with their boards. Although some users prefer to not use software to tune their overclocking, in this day and age, doing so is more than safe since ASUS has heard those complaints and put work into making their software the best it can be. ASUS's own AI Suite makes a return, as does an ASUS version of CPU-Z to verify your clockspeeds and the ASUS Boot Setting Tool to quickly get you into the BIOS when you want to make changes there.
There are a plethora of tools here, some of which you may find useful, and some you might not. Whatever it is you want to do with your PC, ASUS has software here to help you get the most out of your ASUS ROG experience.
KeyBot II and the Lighting Control tools are a bit new, but the MemTweakIt software is quite old indeed. I've used it many times to show memory timings in some of my memory reviews, even going back some years ago.
There is also the ROG RamCache software, and ROG RamDisk, so you can use all of that huge 32 GB or 64 GB memory kit you might have installed. There is even a web-storage tool (with a set amount of free data hosting), great for storing all the software for readily available access at a later date!
