4690k is stronger cpu, you can push it to 4.5-4.7 easily also hyper 212 Evo is good cooler, works great with Intel. Overclocking is step by Step method, you can't go directly on some frequency and voltages. If you do that you will get unstable oc and it will produce a lot heat.First Download thecpu stability testing software prime95 from here :

Don't overclock by any software because overclocking is not the thing that can be done by software. First set the XMP memory profile (if exists) enabled to set your RAM correctly. Then Go in BIOS and find the CPU clock ratio, this is the multiplier setting. It starts at a multi of A (some no.)x 100(BCLK)(normal factory settings) to give you A Gigahertz. So up...
