neg 0.090v CPU and neg 0.025 iGPU this seems to have better scores for single threaded, or not highly optimized multithreaded setups... but is actually worse on the multicore tests.. tho I havn't had time to try actual productivity and media files or civ 6

I will say that I changed my mind, since I have run tests many times and I am now eliminating the outliers. I still picked the lower part of the range for this. This seems to be the best profile for single threaded while not having to worry about being at the limits of the cpu and it is very close to the best I can get with all core, while still being rock solid stable and with enough margin left over to feel good about it not having issues later in its use life. If you have a similar or same edition laptop, these are my recommended starting values for undervolting. if you use a i7 8565u but not a zenbook, this is also my recommended starting values for you to test your system. good luck

ONE note!!!! I haven't done a multi day stress test yet. that is what I will be doing while I sleep. but I am fairly sure this is going to be a good optimization. I am getting 20% sustained better performance from my original stock on most applications that use either single thread or even all core/thread
