Okay let me just point out just because something is working that doesn't make it stable. You could stick a server in the middle of the desert at 150 degrees and it will run fine....the question is for how long. Every device has a lifetime and by stressing it constantly you will reduce that significantly. Don't get me wrong you might be able to run that 846 for a year or two until you upgrade your phone but if you want it to go the distance you should take it easy.
Also i've noticed that more and more people want to overclock to ridiculous speeds (both on phone and computers) for absolutely no reason. If your phone/computer is running fine and apps do not lag then why overclock? No need to overclock if you're just doing day to day stuff like texting, browsing, etc. I've got a buddy who insisted on overclocking his already nice computer when all he does is browse the web....absolutely useless.
