Hi all, glad that I found this thread. Just built myself a Core i7-7700K with Asus Z270E motherboard PC. I used Asus ROG forum Kaby Lake overclocking guide.

I was doing this stress test at room temperature last night, ~29'c room temp.

I can only achieve 4.7GHz @ 1.29v and stable with 16GB memory XMP to 3200 MHz. Stress test using RealBench v2.43.

I started with:
i) 1.3v and 4.9GHz it rebooted right away when I ran RealBench. Memory at default 2133MHz.
ii) Then 1.3v and 4.8GHz it ran OK, if I memory XMP it to 3200MHz it blue screen during RealBench
iii) Then 1.3v and 4.7GHz it ran OK, XMP memory OK, but quite hot when running RealBench, hit 87'C
iv) Then down volt to 1.29V with similar setting, temperature ~80'c to 83'c full load.


I will follow the guide here to try out other stress test software. Will post some photos this week if time permit.

Some question to bro owikh84:
1. owikh84 you have really good overclock results at such a low Voltage. Congrats! And your temperature runs cool too. Can you share with us your cooling solution?


I'm using 3 fans as front intake (2 fans from Corsair AIO H100i v2), and another 3 fans as exhaust for hot air (2 at top, 1 at rear). Using Corsair Carbide 400C case.

Hi,
If you run some synthetic benchmark, like Realbench, what is the temperature?
My Kaby Lake core i7-7700k, I can only OC'ed to 4.8GHz, Realbench temp reaching ~88'C max, if I clocked higher I'm really not comfortable with the temperature.
But come thinking of it, our daily tasks (surfing, gaming) we don't push the core going 100% utilization like what RealBench does, maybe I should go for 5GHz? (without running RealBench to stress test)...as long as it didn't blue screen when I game, I should call it stable and good enough. Is this a good way to judge a system as stable, meaning running my own apps and games, without doing RealBench?
