Is my i7 7700k overvolted?
Hi everyone!
I'm running the i7 7700K at stock speed of 4.5ghz, 1.284V, and I haven't adjusted any voltage settings. It reaches around 70°C during gaming (just a few games). My motherboard is a Z270x K5 AORUS with the latest F9C BIOS, and it doesn't let me change the Vcore—I think it's a bit too high.
My cooling solution is a custom loop with 360mm fans.

My ASUS Z270F set a comparable VCORE voltage for stock on my 7700k, but I adjusted it manually to 1.2v and it remained stable. Motherboards often allow more flexibility with voltage at default settings. You might be able to lower it further if desired. This board supports changing the voltage via any BIOS version; you likely just need to disable automatic adjustment.

What you demonstrated in that screenshot refers to VID voltage, which differs from VCORE voltage.
The voltage changes according to the clock speed. During factory overclocking, the CPU consumes higher voltage.
Voltage changes with clock speed. During CPU boosts or factory overclocking, it requires more voltage. However, it probably doesn't need a lot of it to keep a stable 4.5ghz.
Depends on the CPU. Stability is assessed after running prime 95 26.6 and realbench for 8 hours each without any problems. Is this really true? I wasn't aware that was a fixed rule for stability. For me, "stable" means the CPU performs well for the intended use—if I can play games for 8 hours smoothly, I don't mind needing stable performance for prime 95 as well. Most 7700k models should remain stable between about 1.2 and 1.25v according to this definition.
You won't mind now, but a computer can remain stable by never crashing, functioning perfectly even as it gradually corrupts your system. In 6-12 months you might question why a game can't connect to the server, you'll delete and reinstall, try fixing it, stress out, share your thoughts on the forum, but the only answer is that your Windows installation is damaged and the best fix is a full clean install. If your CPU works well for you, that's great. But this isn't wise advice to give others when you're not sure of the consequences.
