1. Trying to undervolt my CPU with Intel XTU so that its not using more power than necessary, and hopefully also reducing its max heat a bit. So far I have only been able to get it to -0.040v at stock speeds without cinebench crashing. Tested it at -0.1v and my computer immediately self-terminated. Does this mean -0.040v is the limit of my CPU’s undervolting capabilities at stock speeds or is there more I can do? I got it up to -0.075 without a total PC crash, but cinebench kept giving me bug reports all the way down to -0.04
2. Are my minimums supposed to be [dipping this low?](https://i.imgur.com/B9ovV3q.png) The video I was watching showed stable clock speeds for the minimum.
3. I read that some 13900k can get pretty close to 6Ghz. I tried doing 5.6 and 5.7Ghz with just a -0.025V offset, but it gave me the bug report on cinebench, and at 5.8Ghz it outright crashed the PC. Did I end up with a CPU that isn’t worth trying to slightly overclock AND undervolt if its unstable at those settings?
Never messed with my hardware in this way before, so sorry if these are silly or dumb questions. Please let me know if more information is needed.
