Hello everyone, I have been creeping on this site for years for help but made an account to help me fix what seems to be my current problem. I will start out by listing my specs and then I will divulge into the issue I cannot seem to rectify.
CPU: i7 4770k (water cooled with an H100)
MOBO: Gigabyte Z87x UD4H
RAM: 16 GB of Corsair 1333
GPU: Sapphire R9 290
PSU: EVGA 750 Gold
Then the average SSD, HDD, and Burner.
Previously I was overclocking on air with a 212 Evo and I was having issues with completely random BSOD's and shutoffs so I figured I should revert it to stock and try with a water cooler. I got the H100 and have watched, read, and been looking for a safe overclocking guide and all of them still result in the random 1/5 boots of inevitable BSOD. The reason I am confused isn't because the overclock fails (because I am relatively new to this), but because it never eclipses 70 degrees with Prime95 running for twelve plus hours without a single BSOD. I ran Prime95 four different times in 12-16 hour increments and it never BSOD, Shut off, or even flinched but randomly if I open my email it will crash. I currently have it overclocked to run at 4.2 Ghz and my HW Monitor runs down as follows:
VID: 1.178
IA: 1.209
LLC/Ring: 1.228
I appreciate any help and recommendations ahead of time! Thank you, I would just like to figure out what is wrong with this thing or what I am screwing up.

Here is probably the most comprehensive guide that I have seen for a 4770K http://www.simforums.com/forums/haswell-48ghz-on-air-building-a-haswell-system_topic46180.html.

It is a bit long but he gives good starting voltages and settings.

While Prime95 or any other stress program really are great for a quick and dirty way to test rough stability they are not in my experience all that reliable at finding absolute stability. It sounds to me like your OC is not 100% stable it is just stable enough to pass Prime95.

I have had OCs that would pass an entire slew of stability tests for hours on end only to crash when I would open a program or run a game. It can sometimes be frustrating and time consuming but the best method I have found to ensure that your OC is stable after an hour or so of stress testing is simply to do the things you normally do on your PC and if you run into a BSOD go back and adjust your OC and try again.

i agree
the best way to test stability is simply to know what cpu usage on average and have that run without any problems 24/7.
i got no damn clue what the prime95 really does but since ive indulged myself into overclocking about a month ago.. ive never seen an error code pop up.
some things like screen stutter or flashes is a sign of instability and absolutely needs to be addressed.
typically u want to watch the temperature when u change any power consumption settings.
u learn as u go and the best way to learn is trial and error really. just dont mess up on voltage inputs/ ie. 1.19v vs 1.91v
as u learn more about oc, u sorta have a mind set on parameters and par for settings.

some things to watch and best to write down as u go so u can compare ur settings
vcore
core temp
bus frequency
core multiplier
dram multiplier
dram voltage
dram frequency
cpu/ram usage/load per program
