Please help me with my overclocking issues!

[TexGuy914]

Hello everyone,
I'm new here to the site. I needs some help with my overclocking issues. Every time I try overclocking to 4.2 Ghz, I get the blue screen of death. I can run 3.8 Ghz with no issues at all. I'm using stock cooler with the chip, but my case has 6 fans. What specs do you guys need?
I5 - 4670k
Asus Z87-k motherboard
8 gb ram - Patriot brand

Here are pics that may help out, I hope! Thanks guys!

My first guess is that your CPU core voltage at 1.2 is too low. As you increase the speed of the processor you quickly get to a point where you also need to increase the core voltage in order to support the faster speed.

We are missing some important other information, however, that needs to be collected before we start making suggestions for increasing the core voltage. Mainly, we need to know what your temps and core voltage are under load. Increasing core voltage will drive up temps and since you are using the stock cooler you will not have much room for that increase.

It would also be helpful to know more about your hardware:

1. Rated frequency and amount of RAM
2. Make, model and wattage rating of the PSU
3. Make and model of the video card

What we need you to do is to lower the ratio back down to the the fastest that was pretty stable.

Download and install these three programs: CPU-z, HWMonitor and IntelBurntest.
1. Open HWMonitor on the desktop and leave it open while you . . .
2. Run the IntelBurntest for 10 rounds on "high" setting
3. Post back with a pic of HWMonitor after the stress test which should take about 10 minutes.

This will give us an idea of what your max core temps are under load. Later, we may also ask you to supply pics of CPU-z as that gives a wealth of info about bios settings and hardware capability.
