So i bought the I5 4690k about a month ago with the tought of overclocking it to about 4.5 or 4.6 ghz. I read some guides about my CPU and how to overclock and came up with the conclusion that i would easily hit 4.5 ghz with 1.3 V at the most. But when i got into the bios and set up everything for 4.5 ghz as the guide showed me my pc didn't even boot. All i got was constant restart with maybe around 10-15 seconds between each one. As i am new to overclocking my question is: Where is my mistake? What did i do wrong? I loaded the default settings from the bios and everything ran smoothly. I read some threads which said that maybe may PSU isn't enough (550w FSP Raider) but the opinions were very mixed and i am not sure if the problem comes from my PSU or from something else.

Specs:

CPU: Intel i5 4690k
Cooling: Cooler Master Hyper 212 Evo
Motherboard: ASrock z97 Anniversary (I have seen people get to 4.5 ghz with the same mobo and CPU easily)
Ram: 16 Gigs
GPU: AMD HD 7950
PSU: FSP Raider 550w

A high quality PSU is essential for overclocking, you need a steady clean supply of power. Your PSU is very low end.

Also there are no guarantees with overclocking, some chips overclock very well and some very badly with most somewhere in-between.

Try overclocking 0.1 Ghz at a time and stress test at each level.

When I had my 4690k all I could get out of it was 4.5 ghz stable. Even then I lowered the multiplier down to 43 so I could drop voltage down and keep my temps in check as well.

You could try the same, or start at 40 and slowly go up till it doesn't want to boot and then lower the multiplier back down by one.

Personally I like to stay below 1.3V. I'm more comfortable with 1.25V max.
