How does Overclocking affect my cpu

I want to overclock my CPU but I'm not sure how it will affect it. I know that the overclocking process doesn't hurt it just the high temperatures can decrease its life. So I was wondering what temperature will my CPU be safe at and what is the maximum temperature I can go to without damaging my computer in any way.

CPU: AMD a6-6400k
Motherboard: MS-7721 (from msi)
I think thats all the important information for overclocking

    Overclocking can actually optimize your pc by running at higher speeds with lower core voltages and thus lowering temperatures. For example, before I oc'd my rig when I did video conversions at stock speeds my temps would hit over 80c; again this was at STOCK (0 oc!!!). When I tried to find my 247 OC I settled on 4.4GHz with 1.145V Vcore +.0085 manual offset. I have sidestep enabled so the vcore drops at less demanding tasks. My idle can be as cool as 12-35C and load is usually high 50s C (including video conversions; that's a 20-30C drop becuase of my overclock settings). So you have the basic concept right that a higher overclock usually requires higher vcore and thus more heat. When I was targeting my oc speeds I once hit 4.8Ghz and ran over 90c and while I could make it stable, other than for benchmarking purposes and bragging rights it wasn't a place I was comfortable running my pc. I now have a pc that runs stable, cooler, and will last as long if not longer than had I left it at stock with the way I use my rig. Just something to keep in mind.
    Typically, if you are patient and methodical and put in the time you will learn a lot about your particular chip and how it behaves but if you just use a quick software utility it usually can run a stable oc but at unnecessarily high temps because the vcore is higher than needed. Too high a vcore leads to more voltage and effectively more heat. Your system is usually more "stable" but not optimal and of course running closer to the throttle point doesn't help the life of your cpu. So, find a good guide for your motherboard and cpu and put in the work to get a rock solid oc and reap the benefits! Have fun!

    The guides will let you know true safe temps, downloads for measurement tools, stress test tools etc. I'll update later if I find you a good one but just google it real quick; sometimes you may find some videos (be careful some people post bad stuff).

    UPDATE:
    Could you find the exact model off the box for your board. I don't see any mobo with what info you gave. Thx. It should be something like:


    UPDATE:
    BEFORE you try anything, make sure you have a good after market cooler and make sure it physically will fit your case/system! Stock coolers are not ideal for overclocking.

    If your case can fit it this is a very good fm2 cooler:

    Here's a different one:

    It's literally case to case, system to system as some will say fm2/fm2+ on the spec sheet but if you read the reviews some people just can't fit them in (larger, higher profile ram etc.)

    Until then this is the best I could find for you:

    I searched it by fm2 socket type. I prefer using guides from overclockers.net but this should still be helpful. Have fun!

    Thanks,
