Few days ago I attempted to use the "Asus optimal" BIOS setting, and manually adjusted it to 4.6GHz and 1.31v . I had done a very stable overclock previous to this on my 6700k, using a Asus Prime Z270-A, which was 4.6GHz at 1.31v. After running the "Asus Optimal" profile (of course i reset my BIOS before applying), a few hours later within Windows I came across a unfortunate BSOD. Because of this I decided default all BIOS settings (now on Normal mode), and then after restarting the BIOS I put my previous overclock settings in (XMP, 1.31v adaptive, 4.6GHz). I booted into Windows and everything carried on as normal.
A day or two later Windows started to lag. And I mean bad. It was terrible. Took about 3 minutes to log in. Everytime I would try to open "Settings", I would receive 20 messages from "Runtime Broker" saying the application is not in the state to be run or something along those lines. Every application took about 2 minutes to completely open, Chrome wouldn't allow me to search anything, and if I was lucky to get onto a page, YouTube videos will not play at all. Sometimes it would even completely freeze up and I would have to hard reset, or sometimes it would drop to like "2 FPS" within Windows for a few minutes.
This morning I decided to disable the overclock. Not sure what came across my mind, probably because I remember seeing similar behavior within Windows when I tried to do a 4.8GHz overclock ages ago. Now everything is fine. I have no problems. But why is this happening? Sorry for the long story but I wanted it to be as detailed as possible and have as much info as possible. And I am not thermal throttling. My speeds are not being reduced and my temperatures are ok.
My questions: Have I damaged some hardware?, Can I go back to my old overclock?, Does the CPU degrade its OC abilities over time?
P.S. The motherboard is a year old, while the CPU is over 2 years. This is because I went through two Asus Z170-PRO's, as they both blew up on me.
