So I just started overclocking, I am pretty new to all this

PC:

i5 4670k
AsRock Extreme4 Z87 Motherboard
Corsair GS700 PSU
Noctua NH-D14 CPU Cooler
8GB RAM - G.Skill Ripjaws 2133hz
R9 280x

Watched the Linus Haswell Guide, started off at 4.6 - wouldn't boot, 4.4 - very unstable, 4.2 - unstable just browsing the internet. All that was using the 'default' overclocking profiles, that already exist in the mobo.

I then tried to change some settings based off some suggestions I saw online. I got 4.2Ghz stable while running the Aida64 System Stability Test (I only did it for 20 minutes)

can you guys help me with my settings? I really want to try get a bit more out of it and lower voltage if possible.

The test I did was 4.2Ghz, 1.3 Vcore Voltage. Rest of settings can be seen in the photos.

Thanks for reading this far, any help appreciated

I don't know about Intel but I think you should disable CPU OC fixed mode, Intel Speedstep Technology, and Intel Turbo Boost Technology. That is if you're doing manual OC. But I maybe wrong.

First, never start with a high clock and back down. While you probably didn't, you run the risk of damaging your CPU. Second, there is something called the silicon lottery. Your CPU may just have a low potential clock. I have the same mobo and used to have the same CPU. I could get to 4.6Mhz at 1.3v (water cooled) or 4.2 at stock voltage (water, or air cooled). Others get higher, others lower.

This is what I would suggest. Revert to the base clock. If you don't have it installed already, I would install the Asrock A-Tuning utility. Set it to performance mode. Click advanced. Then go to auto tuning and hit apply. This will run a test to see what your CPU's stable OC is. Do some web browsing, restart your computer, run your benchmark software (I recommend OCCT), and if everything is stable then you are good to go.

If you really want a higher clock, run your benchmark. Then in A-Tuning, increase your voltage, clock in increments of .05 and .1 respectively. Realistically, stop your voltage around 1.37 and your clock at 4.8 (if you can get that high). If it crashes, lower the clock and increase the voltage. Again, I would stop at 1.37v.

Increasing the voltage will lower the life span of your CPU. It can also permanently damage your CPU if you set it too high (hence why you should stop at 1.37).

I hope that helps. Happy over clocking.
