Hi.
Regarding your stable 4.2ghz overclock, could you confirm if these readings are accurate or if adjustments are needed? I noticed the memory/SPD seems inconsistent, and I think increasing bandwidth might be necessary. I used a multiplier of 42 and set the CPU voltage to 1.24v. After several stress tests, temperatures stayed below 62°C with good results. Thanks.
Your approach will vary based on the specific motherboard BIOS. Increasing the multiplier slowly while keeping everything else at default is a straightforward method. I also prefer adding speedstep (C1e?) and adaptive voltage, which helps lower the multiplier and voltage when the CPU isn't under heavy load.
It looks good overall.
The maximum vcore on Skylake appears to be around 1.40v.
Here are some OC statistics:
I5-6600K
4.9 3%
4.8 23%
4.7 44%
4.6 85%
I prefer stress testing with OCCT, as it uses a more typical set of instructions.

Ah yes.
In this scenario, the system is dedicated to music recording, where the CPU's peak performance matters most. (low latency, high bandwidth are essential, even if the computer perceives it as idle.)
Therefore, in Windows, for instance, I configure both the minimum and maximum CPU levels to 100%.
This seems effective based on the results from CPU-Z.
ohm-ish :
geofelt, why did you mention the max voltage and stats for skylake?
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.
But I'll never approach 1.4v again
This adjustment looks strong. I think I'll keep it like this.
