Hi.
For my modest stabile 4.2ghz overclock, can you please say if all these readings are correct/optimal or should anything be different?
The memory/SPD part looks off to me, but I guess I have to multiply the bandwidth?

I only set multiplier to 42 and cpu voltage to 1.24v.
Did a lot of various stress tests with good result, and temps never exceed 62 celcius.
Thank you.

Motherboard: ASUS Z170M-PLUS.
CPU: i5 6600K.
RAM: Kingston HyperX FURY - DDR4 - 2 x 8 GB - 2133mhz

How you oc will depend on the particular motherboard bios.
Simply raising the multiplier gradually and leaving all else on default is an easy way to do it. I like to also implement speedstep(C1e?) and adaptive voltage which will reduce the multiplier and voltage when the cpu is not working hard.

So my voltage should be different, or?
I started with 1.2v, but that destroyed my windows installation o.0
(or maybe it was the bios bug, which I updated)

Ah yes.
In this case, the computer is for music recording, where the instant best power of the CPU is critical. (low latency, high bandwidth etc. are important, even when the computer think's it's "idle").
So, in Windows for example, I set both minimum and maximum cpu level to 100%.
That alone seems to do the trick, according to CPU-Z

When you have a "K", the presumption is that you will overclock(aka raise the multiplier)
One should know how that works and what you can realistically expect.
When you raise the multiplier, the vcore increases. At some point, there is a danger to the longevity of the chip because of high voltages.
I have nor found any solid documentation on what that safe limit is from Intel. (or elsewhere for that matter)
Silicon lottery who bins chips uses that 1.4 vcore as their upper limit, and that is where I got the stats.

How high one can safely oc is determined by your luck in getting a golden chip.
Higher vcore results in higher temperatures. One controls temperatures by limiting the upper end of vcore.
Not so much by controlling the temperature so long as it stays below the 100c. or so that shuts down the cpu.
