suspicion about i5-8600k overclock (your help is really appreciated :))
Hello there, I'm just starting out in the overclocking scene, but I successfully pushed my CPU to 5GHz (i5-8600K). I didn't see a significant boost in performance, which is what I meant by a big improvement. I managed this with a voltage of 1.28V on a motherboard that's known for being unreliable in this community—specifically the MSI Z370 Gaming Plus. Not only did I reach this speed using just 1.28V, but the temperatures are really raising my doubts about this overclock. During a stress test lasting 10 minutes, the peak temperature reached 55°C, which is way higher than what I expected. In comparison, the H100i V2 reached 82°C (https://youtu.be/LvIudPHLiog?t=3m14s). This experience made me question whether my overclock was just a mistake or if I made a mistake that shouldn't have happened. I'm really confused and would appreciate any feedback on my settings or results. Thanks for your help! 😀
You have a very strong CPU. To confirm, run CineBench R15 and compare your single CPU score with other 8600K scores; this should indicate your position and whether it qualifies as a valid overclock. Personally, I believe you're in good shape since similar models have achieved low-voltage overclocks at 5GHz... As noted by the InvalidError, most high-end motherboards are built with solid components, even mid-range ones are more than sufficient.
The GTX1060 performs less efficiently than a 5GHz i5-8600k. Your 3DMark score only improved noticeably after upgrading the GPU, which means you're mainly limited by the graphics card. To achieve more significant improvements from CPU optimization, you'll need a more powerful GPU.
Well that's correct and makes sense, but I haven't considered it closely yet, thanks. Just a note about the voltage—I've adjusted it to 1.265, yet the PC still functions. It's really surprising how it can work despite the motherboard's poor reputation (T R A S H)?
I'm not sure if anyone can interpret this image better... is there anything incorrect here?
The majority of reviewers rely on a single sample unless they've faced significant issues with their initial board or CPU, requiring additional units to complete their tests. Drawings of conclusions or broad expectations shouldn't be made from such a small set of reviews. High-end boards from leading manufacturers generally perform well, and even budget models can last a long time when used within their intended specifications. I haven't purchased premium enthusiast motherboards or RAM, yet all my systems have functioned without problems for over ten years, except for occasional overclocking attempts, faulty new RAM, and a few HDD failures.
You possess a strong CPU. To confirm, execute CineBench R15 and compare your single CPU score with other 8600K scores; this should indicate your position and whether it qualifies as a valid overclock. Personally, I believe you're fine since some 8600k and 8700K models have achieved high performance at low voltages around 5GHz. As the InvalidError warns, most top-tier motherboards are built for reliability, making mid-range options more than sufficient.

Here are your benchmark results:
4.7 GHZ @ 1.2 Volt: 1147
5.0 GHZ @ 1.3 Volt: 1238
5.0 GHZ @ 1.26 Volt: 1236
5.0 GHZ @ 1.24 Volt: 1237
5.0 GHZ @ 1.23 Volt: 1238
5.0 GHZ @ 1.225 Volt: 1236
5.0 GHZ @ 1.22 Volt: 1221 (tried several times to confirm)
5.0 GHZ @ 1.2 Volt: Crashed
I compared these findings to the article at http://asknotes.com/2018/02/18/new-pc-build-and-overclo... and it seemed background applications might have influenced the test. Apart from that, what are your thoughts on these outcomes?

You're on the right track for an overclocked 8600K—perfect! Your vcore looks solid, especially with the 1.220 volts at 5GHz being impressive.
