I had a 3570K mildly overclocked on a Gigabyte board since around 2013. Earlier this year it quit booting. I could go into the BIOS and see all the drives but it wouldn't actually boot Windows. Since it was that old I took the opportunity to replace it with an 8400, and since it wasn't important any more I decided to try delidding it. I went old school and just used a regular razor. Relidded with AS5 and, initially, I'm using nothing to reseal the heat spreader; it's just held in place by clamp pressure from the socket and Hyper 212. Booted Ubuntu from a live CD the first time. The BIOS is set to overclock to 4.0 on all four cores but I haven't done any testing yet. First thing is to see if I can get stuff like hwinfo64, prime95, occt, or equivalents for Linux, and then see how much faster it'll go. I know I should've cleaned the board & IHS up more but I was more concerned with making sure I hadn't damaged anything. If I bother to use this for anything after stability testing, I'll do it.
