this is my 1st time Undervolting. this last set up I've tested lasted 5 different 1 hour runs. pretty much most of what I tested before was junk and would crash in 5-7 secs into Aida64 stress test. I want several profiles so that I can switch between them when necessary. like I want some over the top overclock that's stable for gaming and maybe one for benchmarking, and definitely a couple for gaming. this one seems to be really good for gaming. im welcome to any critique. I just want some advice to keep this thing running snappy and cool so it lasts me awhile.
