Hi all. I recently just built my second ever PC, link below:

and am very excited about it. The CPU is delidded, and I have a Corsair H100i to cool it. After researching a bit on overclocking, I decided to try a 4.6GHz OC. I went into the UEFI on my mobo and changed my core and cache ratio to 46. I also changed my vcore voltage to 1.220, and my CPU input voltage at 1.8. This was a fixed voltage. I then increased my RAM speed to 2400MHz via an XMP profile.

I have a few questions about what to set some of the options at in the UEFI. Such as CPU cache override voltage. Should this be set higher than the vcore or the same as it? Also, is 1.8 a good input voltage for the CPU?

I would think with the delidded CPU and H100i I would have no problem pulling off an OC like this. However, my computer blue screened when I tried to restart it and gave me multiple errors such as "whea_uncorrectable_error". When it blue screened, I had to turn off my PC manually and let it reboot. It then restarted several more times before even showing the ASROCK screen from which I could go back into UEFI. I then reset everything to default settings in order to get my PC to boot. Which it did, thank god.

Can anyone offer any insight as to why this OC failed? My computer is up and running right now, and HWmonitor shows that my idle CPU temps are around 25C, definitely cool enough. Help?

You're trying for too much too soon. On OC of 4.6 GHz will require more voltage, apparently, for your setup.

Try for a multi of 4.2 at 1.220 Vcore and see if it will boot. If not, increase Vcore by 0,010 v steps until it works at 4.2, then increase to 4.3 and try again.

On air, the Max recommended Vcore is 1.300 V. but I don't know how high it can safely go on h2o.

I believe that my CPU Input Voltage is set to 1.900 V.

Thanks that has helped a lot. But too much too soon? Do you have to break in your CPU or something so to speak?

No. Not at all. Its just that OC'ing is not a one-step process. All chips are different and you need to find what works for you by one large step (4.2) followed by smaller iterations until you reach the max stable OC for your chip and system. There is no "one size fits all".
