Big lol on this
This is true ON ANY OVERCLOKING not just non k cpus
What Intel really means is that they want money from you to be able to do this
I had as asrock z97 board that could over clock non k Ivybridge cpus, its still running nearly 10 years later, no issues and will only be retired because Ivybridge is now not able to compete with modern cpus
Don't listen to this rubbish, yeah it's true, but this entire site and community is built on that risk and they told us that years ago and then sold you a warranty incase you blew it on your officially approved overclocking cpu.
