Overclocking 4770K

[AryanXD]

I got a 4770K and the h100i, under stock I get normal temps and whenever I attempt to overclock (4.5Ghz) specifically my computer blue screens mid way through a game. I can boot at 4.5Ghz under 1.255V and my temps are a little higher but stay within 70-75C (When I load a game). Should I increase my voltage or should I just reduce my clock to 4.4Ghz? 

 

I also run the fans on the h100i on quiet mode because under balanced they spin like at 2K RPM and their loud as hell, does it matter if you leave the fans spinning at a low RPM when running a game? (they spin at 1300 RPM under quiet mode)

I don't think you're overclocking correctly, you need to do a stress test every time you crank up something, that means running something like prime 95 or intel burn test for a few hours. Also remember every CPU is different, no matter how good your cooling is, some CPUs just won't overclock very far. Your temps are still fine but are starting to get a bit high, keep your voltage under 1.4v and your temps under 80-90c (while in a stress test).

How long are you stress testing? is it 70-75C right away during a stress test, or is that a while after it reaches its resting point at max load. Also, Those temps seem about right for the h100i. You may want to look at better pressure optimized fans. Noctua NF-f12s, Gentle Typhoon AP-15, etc. Haswell, has heat issues. Do A stress test of longer than 1 hour, see if it can last without crashing.

You have to run a stress test utility (I prefer to use two) to validate the stability; you can't just set an overclock and immediately start playing games.

I would use AIDA64/Intel Extreme Tuning Utility because I heard that P95 is bad for stress testing on Haswell because it gives it too much voltage.
