overclocking i7-7700k but maxing out at around 5 ghz!
Hello everyone, I've been experimenting with my 7700k recently to explore its capabilities. I've reached a stable 5.0ghz, but consistently can't surpass that. I'm operating at a solid 1.325 vcore maximum temperature during the full Prime95 stress test, which is around 78—giving me some breathing room, though it still doesn't break through. I've tried boosting the ratio to 51 and pushing the vcore up to 1.38, resulting in smooth Windows booting and decent stability, but all stress tests fail. My only overclocking attempts have been with the core ratio. Should I consider increasing the base clock, or is it best to accept what I have? Any advice would be greatly appreciated.
I could verify your minimum stable voltages for both 4.9ghz and 4.8ghz with your 5ghz...if you need extra accuracy, 4.7ghz is also worth checking. Stick to the old methods and graph voltage against frequency. If your curve stays fairly smooth without a sharp jump, it might be worthwhile to focus on 5.1ghz. But if you see a big spike in voltage, chances are you're stuck at 5ghz—still decent. It's easy to feel let down by a chip's output, but we all aim for that 1% precision. Ultimately, you want to avoid being one of the silicon losers in the 4.7-0.8ghz range.
There is more to it than just temperature... there is a physical limit to the silicon. Have you heard of anyone going over 5.0 GHz with any Intel processor?
5GHZ is a good overclock for that CPU. It may be possible to squeeze more out but my guess is your getting close to you CPU ceiling (without going extreme cooling). I can only assuming your water cooling with those temps/speed/voltages. If not I am duly impressed. I guess my question to you is how linear has the clock speed increase been compared to voltage? Did you have have to crank the voltage more to hit 5ghz compared to 4.9/4.8/4.7/etc or were the increases all fairly even and incremental?
Other users shared these overclocking statistics from various sources. For a stable increase to 5.1, aim for around 1.380 to 1.420 volts; you might start with that range and check your temperatures. Many opt to lower the CPU temperature below 85°C after use to avoid damage. Typically, people either delay overclocking past 5.0GHz or set up a custom water cooling loop. A 5GHz setup at 1.325V is considered solid and worth trying.
I think you're close to the maximum. Besides cooling the processor with liquid nitrogen, there are still other possibilities.

i have heard of a few but they are rare. No doubt the OP has a good chip though. 5GHZ isn't guaranteed with any K chip. Seen some less fortunate folks top out at 4.7ghz-4.8ghz. Point being i wouldn't expect anything more then 5.1ghz without going to LN2.

Yeah actually I frequent forums and see people get 5.1 and 5.2, thought maybe I could be a lucky one
That's why I was inquiring about your voltage scaling. It's not very typical, but some people have reached speeds over 5 gigahertz.
I reached the goal effortlessly, with voltage set to adaptive at stock. At times it was 1.4 just to push up to 4.5. I manually adjusted it to 1.3 and achieved full 49 ratio, only needing a small tweak on vcore to hit 50 ratio. Probably has a solid chip, but still didn’t meet expectations somehow.
