i7 6700k OC Help?

[APatientGuy]

Hey everyone. I just managed to overclock my i7 6700k to 4.5ghz with 1.325v for the voltage. I used linustechtips' overclocking video to guide me, but I still have a few questions. The CPU stayed at around the mid 60s during the course of a 15 minute realbench stress test, and about a 1 hour and 30 minute aida64 stress test, never going above around 74C. Now, should I push it to further speeds with the same voltage setting, try to lower the voltage and keep it at 4.5ghz, leave it here, or something else? Also, what temperature (from the picture linked below) do people generally refer to when they are talking about safe max temperatures? Individual core temp? CPU temp? CPU package temp? I will also leave my part list so you guys can better come up with suggestions suited for my build. Please disregard the gpu, I will be getting a gtx 1070 and am currently using the iGPU.

If you are willing to spend more time with OCing, it's advised to both try lowering voltage as much as you can AND try to raise frequency. You might have gotten a golden chip that can go even further on speed or just needs a tiny bit more voltage to get a frequency notch. Or it could be a chip that doesn't boost so much, but doesn't much voltage for the little it does.

 

And don't forget Bclk, it can give you that extra boost you may not be able to achieve with just multiplier tweaking. You did buy a Skylake CPU afterall, so you might as well make use of it's features rather than letting them go to waste... here's a video that'll help you:

 

Leave it at that when you feel like you don't want to spend any more time.

All of them, they are related to each other. Don't let any go over 85.

I'm curious, this does seem to be a consensus overall but I'd like to inquire why you state this? Is this just because of the consensus or is it some sort of rule of thumb (or data point) pertaining to Intel's ARK data?

You can actually go even higher than that. But to give it a margin of safety to account for climate changes, dust build up, load spikes and etc, we usually call a round number such as 85 as our max.

Fair enough. Thank you for replying so quickly.
