actually i just tested the latest 0.8 ver and it seems that it's compatible with all mobo brands, the v0.8 beta 3 is(the 0.7.something is not), i provided the link in my previous post,
was able to open it on my asrock ab350m mobo on r5 1400, feel free to give it a try after you will save your cpu as stock volts and stock GHz in bios
// alright so i gave it a test run, i'm currently far away from my R5 1400 cpu so i used teamviewer to access it, it already runs OC to 3.6 @ 1.35 in bios, so i can't really disable that from a distance, i input 3.5 in ZenStates 0.8 beta3 @ 1.4V and clicked on "autostart" and "apply on boot" , then to Apply and Save(save is important)
rebooted, checked clocks and volts - 3.5 & 1.4V , meaning that it works on boot just fine. 😉
don't forget to input stock clocks and volts in your bios before saving your desired clocks in ZenStates(to avoid any potential boot problems from bios side), hope that will "fix" your issue for time being
