Hi everyone, just joined this forum (though I have been reading threads for years now). I recently upgraded my computer - my CPU, my motherboard, RAM, and a cooler. Here are the parts:
- CPU: Intel Core i5 9600-K with an Asus ROG Strix Z390-F board.
- RAM: G.Skill Trident Z RGB 16 GB running at 3200 MHz.
- Cooler: Cooler Master 212 Black Edition, which has a full RGB light show.

At first, it was warm as I put everything together - the stock temperature was about 35 degrees when nothing else ran. Then I followed this video on YouTube to try my first over-clocking. The link is: https://youtu.be/bD1Ze80GpLo (Note that the BIOS in that video doesn't seem like it matches what I have).

I did exactly what he suggested, even though my BIOS menu wasn't perfect. Here are some results (roughly):
A) 5.0 GHz - The voltage went up to 1.495 volts. Sorry, I don't know what the stock voltage was back then, but it jumped way too much from 35 degrees to 55 degrees.
B) 4.9 GHz - The voltage got a little lower, around 1.39 or 1.40 volts. The CPU stayed at about 50 degrees.
C) 4.8 GHz - The voltage dropped down to maybe 1.35 volts. The CPU is still sitting at about 50 degrees.
D) 4.7 GHz - The voltage went way down, all the way to 1.296 volts in the software called "CPU-Z". The CPU temperature actually got lower, dropping to 45 degrees (but not as low as those stock levels).

Before I melt my motherboard or CPU, does this computer look like it is stable at 4.7 GHz? I am very surprised that the voltage dropped so much. Is that normal? Sorry in advance if these sound silly questions - remember, I am completely new to overclocking!

WAY too high ! makarastar , Here's the Maximum Recommended Vcore per Microarchitecture from 14 to 65 nanometers since 2006: We know that over time, excessive voltage and heat damages electronics, so when using manual Vcore settings in BIOS, excessive Core voltage and Core temperature...

I just tried it out and turned up E) at 4.6 GHz, but my voltage dropped to about 1.23 volts while the CPU stayed hot, around 46 or 47 degrees Celsius. If you look back at all that info here is where I feel safe: if 1.2 volts is a limit and crossing it hurts your chip speed, then yes, 4.6 to 4.7 GHz sounds like my new "safe zone." But wait, some sites say 1.3 volts is too dangerous to cross because chips get worse that way. So if they are right... did I miss out on the Silicon lottery? Or does running at 4.6 or 4.7 GHz look okay for this specific CPU model?
