You win a 5 GHz 8600k! Congratulations. Not bad on a D14. I put a D15 with loud fans on my current system. I wonder if temps or process are holding back Coffeelake at those levels? What kind of voltage scaling are you seeing above 4.8 GHz?
Indeed, it must be the easiest overclock ever. Easier than the Sandy Bridge even.
To tell you the truth, I only need a gaming stable 5Ghz profile, for benchmarks. I will mostly use it at stock or maybe a tiny bit above that. Like I did with my 2500k all these years. I am currently trying to figure a way to just mildly increase the boost clocks, along with very little additional voltage, say +10mV, for that small performance jump. It's pretty speedy as it is. The 3200Mhz ram also help I think.
At stock it's already 100% faster for my encodings, compared to my 4.3Ghz 2500k, which was its every day clock. Ok anything would be 100% faster than my 2500k in multithreaded apps, lol. I think I will aim for +200Mhz all core bost and +500Mhz single core boost, with a max 100W ceiling, as a middle ground between stock and OC.
For now I have succeeded in 5Ghz with +80mV offset voltage, which results in 1.328V in max load. Gaming/Benching temps are good, so I'm happy.
The 4.8Ghz profile provided by the motherboard, was using 1.41V fixed voltage, which was a no go.
Is 1.328V too much? Should I aim for a lower offset?
