I am trying to run this Intel I7 6700K processor faster by overclocking it on an MSI Z170A Krait Gaming X3 board that has 16 GB of RAM, liquid cooling, and is already set up for that. I am slowly raising the CPU ratio and the voltage while keeping the RAM slower than what it was originally to stop the testing results from showing those speeds too soon. After doing a final test by turning on the XMP profile, my only other attempt would be to turn off settings like dynamic frequency and voltage boosters or power-saving features (though I know that in the real end-test I will have to turn them back on because they are needed for me).

I need your help with these questions:
1. Which stress test should you recommend so I can check if the CPU stays stable during normal daily use?
2. Besides adjusting the CPU ratio and voltage, can I try changing other settings or voltages to stop instability during the stress test (for example, tweaking other BIOS voltages)? Also, what about other options like core override or ring frequency? If at 100x46 with a vcore of 1.32v it works fine but at 100x47 with the same voltage it fails, should I just try to increase the vcore instead?
3. In case of instability, can increasing BCLK and decreasing the CPU multiplier help, make things worse, or is it basically the same thing?
4. Can core override be used as a way to adjust the vcore mode?
5. Does leaving the ring frequency at its default (around 4100) hurt stability, or would lowering it be better?
