Are long stress tests necessary?

Doesn't your processor reach its max temp in minutes when under load? Why do you have to do it for several hours or more? Is ok to run it for only 30 minutes or so when adjusting your OC? So, raise multiplier until it crashes, then raise voltage etc. until you reach target OC, THEN stress test for a few hours?

From my experience the best Stress Test is to leave it for a couple of weeks at your prefered oc!! Play your games normal etc... watch for your temperatures and such with a monitoring programm. See for any freezes or unnatural behavior everything is fine then you are fine!!!

It is usually good to use prime and other stress tests, ( Do not use intel burn test, it kills everything. I do not see the point to stress it that much when all your apps will never even stressed it so much) to see the temps right away!! Cinebench is good and fast way to see temps and check for any throttling and see how effective your oc is!!

I read that memory plays a role in overclocking as well. Like when you OC your CPU, you have to change some RAM settings as well. Is that just because they want to OC their RAM or does CPU and RAM OC'ing go hand in hand? In other words can I just OC my CPU and leave ALL RAM settings alone? I don't really care about RAM very much.

Well in all the Unlocked Processors ( Unlocked are the ones where you can change the Multiplier) which includes the Intel k series and all the Amd, there is no need to change anyhting in your ram. In locked cpu's you have to change the FSB where it has impact in Cpu clock speed as well as Ram.

Do all tests push your cpu to 100% and just keep it there? What makes some tests (prime 95, Intel burn etc) "harder" than others and what's the difference between a game than maxes your cores vs. a test if they both bring your cpu to 100% anyway?

a stress test such a p95 will put an artificial 100% load on every core the CPU has. You will most likely never see a load as harsh as this (closest I have found that approaches p95 heat levels is handbrake encoding 1080p at custom settings, still about 6-7c lower than p95) but for an overclock to be stable it has to be able to run at full throttle without crashing or throwing errors.

Ok, I ask because BF4 maxes out my cores so I guess I'm asking if 100% from a game vs. 100% from a stress test are different in "toughness" or if 100% is the same no matter how it happens (gaming or stress testing). Basically, can 100% usage be more demanding with different tests?

As long as your temperatures are fine then no damage will occur. Running a heavy stress test for that long would be to no benefit. Do keep in mind how much power you may be using overclocked and the limits of your power supply. If it passes 6-8 hours of p95 blend test with no errors or dropped cores, then I would consider that overclock stable for 24/7 everyday use.

lastly, if you're in the process of manual overclocking, and you are changing settings then testing then changing settings etc. Can you run a stress test for a short amount of time (like 30 mins) before increase the ratio (frequency)? Then when you're happy, do a final long test (6-8 hours) to really test it, or do you have to do really long tests every time you make a small change (like 100Mhz increase). If doing it that long way it would take days to get from 3.4Ghz to say 4.2Ghz.
