AIDA has a heavier test, I also find that OCCT has a better test...both use AVX instructions which will run your CPU past 100C for a millisecond before it can throttle.
The only person playing is you...I am cleanly stating, if you don't want to put forth the proper effort, then don't overclock.
How easy is it to OC a 4770k? Quite...look at my system specs. Go into your OC settings in BIOS/UEFI and set your voltage to 1.25v, and set the CPU multi to 45X for all cores (sync all cores). F10 for save and reboot. It can be that simple. Can your chip do the same with less voltage? Maybe... does it blue screen and need more? Possibly.
There's trial and error...it's not exactly clean. You might hit 5GHz, but I'd say set a goal for 4.5Ghz, and when everyone tells you the common sense, safe and proven methods of learning to OC you shouldn't ignorantly blow them off. That will bite you more than anyone here, and will only cost you in the end. But we'll be more than happy to make suggestions, but a time will come when noone cares to when suggestions continually fall on deaf ears. Food for thought.
Again good luck, and understand that Haswell is a little more finicky to OC than a Core2. You had CPU voltage and FSB on Core2. Here you have Multipliers, different types of voltage...I prefer Adaptive, others prefer solid with max LLC, some increase the Wattage settings, are you going to use the XMP settings with your memory or not? Will it cause issues? It might...it might not. Do you need to manually adjust your memory? Most likely...I prefer to anyways on Haswell builds. Take it from someone that's been doing this for a long time, since well before Core2's. Spend the time to read and put forth some effort in learning how to do it right, read a couple guides, read the TPU Haswell Club thread, buy the Intel Performance Tuning Plan, and then you'll have some fun. Wish you the best of luck.
