Computer crash when overclocking

[slyer3726]

I have been trying to overclock my 4770k and i don't know much about overclocking so i just used AI suite 3. I set the desired overclock to 4.2 GHz. it works fine for a while, I can play games, I run a stress test and it doesn't crash. But if i leave it on over night when i wake up the following morning it either isn't on or its frozen. I don't know whats wrong, anybody have any ideas?

My computer specks
i7 4770k
corsair rm 750
corsair h100i
gtx 780ti
120 gb ssd for os
1 tb hdd
16 gb G.Skill Ares 1866

So this is a little tutorial I have put en for people that are new to overclocking and I think you will really benefit from this.

You can get more performance IF your cpu is bottlenecking your GPU or if you're doing rendering, if your GPU isn't being held back by your cpu the fps increase will be minimal 2-5fps or in some cases you wont even see any increase, But if your cpu is bottlenecking sometimes you can see a 10 or even 15fps increase and better average fps with less and smaller drops.

Now OCing is done in your motherboard BIOS, you can do it with a software called AMD OverDrive it wont probably kill you but its just not the proper way of doing things.
You will need a few programs for this.
OCCT - stress testing program that will stress your cpu to 100% ( Run a linpack 90% stress test for atleast 15minutes between overclocks and atleast 2 hours after you're done to make sure that your CPU is stable) *You can also use intel burn test or aida64 (aida64 costs money)
HWMonitor - monitoring temps
CPU Z - monitoring Voltage and clock speed.

Now I would strongly advise you to read the overlcoking guides in the forums because I will try and keep it short.
First of all run OCCT and monitor your Core Voltage using cpu z and write down the numbers for ex 1.356V, you'll need that later.
Overclocking is done by entering the advanced BIOS.
When you enter the advanced bios first of all change your Voltage to Override and set it to whatever you saw in cpu z but add 0.010V so if cpu z said 1.35V put in 1.36V this will give you a starting point after that is done increase the multiplier by 0.5 in your case that will add 100mhz and boot into windows run the stress test and if its stable add another 0.5 (or a 100mhz) now when your crash it means you need to add more voltage, so just bump it up by 0.05 or 0.1 and see if it works after that.
Safe temps for the cpu are 65C and 70C for the socket.
Also make sure your motherboard has heatsinks on the vram or else you might damage them if you oc to much.

Overcloking is time consuming thing so be ready to play in the bios for atleast a few hours.

And remember to choose the solution which helped you so another people can find it!
