Hey guys, I just built my first desktop and I have been dabbling with OCing, but I would like to get more serious about it since I have such a nice CPU and cooler (H80i). That being said, I still have quite a few questions so I would greatly appreciate your help. Here is an online version of my CPU-Z system specs: CPU-Z

-When doing an OC, should I edit the BIOS settings myself or use Asrock's preset settings?
-I tried using the Asrock settings to OC at 4.5 GHz and the computer is working well, but when I used Prime95 for some stability testing the temps went up to about 70 C (pretty low, right?), then it shut off...so I'm confused there.
-When OCing, is heat and voltage the only thing I need to monitor?
-Should I change the speed of the RAM if I am going to OC this much?

Thanks for reading/helping!

i5 4690k OC`ed directly to 4.5Ghz?
The boost clock of 4690k is 3.9 Ghz so when OCING you must 1st determine the Voltage of 3.9 Ghz, after determining the voltage of this clock/speed you can now add increments of 0.1 (3.9-4.0) and test if the voltage (3.9 voltage) will be stable with this clock/speed (4.0).

After determining that you are stable add again (4.1) and so on until your computer crashes when doing stability test.

After your computer crashes let`s say at (4.3 with stock voltage) bump up your voltage, let`s say from 1.2 - 1.225 and check again for stability.

If your system becomes stable with this voltage then again bump up your clocks/speed (4.3-4.4 and so on) until your computer crashes again, if it crashes again bump your...
