I don't have a problem with tinkering around with stuff like this for your own fun,but I have large concerns and or objections. 1. It is simply not accurate to say that under-volting a CPU is always safe. It's true that modern CPUS have much more headroom positively and negatively than earlier generations, BUT, Intel and the manufacturers spend a great deal of time trying to figure out the ideal voltage/clock speed etc. Variations from those rated speeds most certainly will cause stability issues e.g. the CPU may be fine but other support chips such as cache, , wiFi etc. may not. 2. I'm in complete agreement with @dstrauss, that nearly 40 years in to the PC era that this is even considered an option that needs/should be done by a mainstream user is absurd. 3. Even if all of the above was ok, you also then will get in forever "Mr. Fixit" mode as each windows or driver update, or for that matter even as the machine ages will tend to break what you are doing Again, if you like to muck around with this stuff and experiment, have at it, but please don't prescribe it as a fix. And now to put my corporate "harda**" hat on. You certainly shouldn't expect most mainstream manufacturers to support you. I know with us, that if a rep hear that, they will politely tell them to call us back when you are operating the system as designed. Note; A couple of the gaming companies do allow for this sort of tinkering, but even they have limits and like for example with Alienware, provide tools which themselves have limits to keep you from going to far afield. Ok end of rant; I'm not trying to offend anyone here, just bring a dose of reality from the business side of things. And I 100% support holding the companies accountable when their system don't work as they should.
