Top voltage CPU core for 7700K to 5.0Ghz overclock
Top voltage CPU core for 7700K to 5.0Ghz overclock
I own an ASUS Maximus iX Hero, an i7-7700K processor with Noctua NH-D15 and MSI X570 RGB.
In my BIOS the CPU core volt is set at 1.114v (default), I adjust it to 1.320v directly without experimenting with other voltages. It appears stable, maintaining 30°C idle and around 50-60°C during gameplay. I ran IntelBurnTest and Prime95 without any issues.
My concern is whether changing it slightly above the default was the right decision or if a minor adjustment would have been better. Also, could adjusting to a lower voltage yield better temperatures?
By the way, I’m new to overclocking; I rely on YouTube tutorials for guidance.
You're likely correct about the initial estimate reaching up to 1.32v. It's an outlier, not the norm...
If conditions are stable and temperatures are normal, it's best to proceed. Testing at 1.31 might offer minor insights but won't significantly change the outcome.

Increase gradually, aiming for the minimum voltage needed to maintain stability during overclocking.
Suggesting gradual adjustments is best. The optimal setting is the lowest voltage that still maintains stability during overclocking.
I adjusted the voltage to 1.300v, which caused a blue screen for the first time on my new PC.
Then I reset it back to 1.320v and it appears stable now.
You should adjust gradually. The best setting is the lowest voltage that keeps the overclock stable.

You're absolutely right about your initial estimate reaching up to 1.32v. It's not a common case, but not unheard of... If you're stable and temperatures are fine, go ahead. Testing at 1.31 would be a good idea, though it might not change much.

By chance, when I reset it back to 1.320v, I experienced a blue screen and my game performance dropped noticeably—about 50-60 frames per second less. It seems the crash could have damaged my PC?
Don't destroy anything at that power setting... it's unlikely, though still possible. You may need to reset your CMOS and begin the process again.

You shouldn't have destroyed anything at that power setting... Although unlikely, it's possible. You might want to reset the CMOS and start your BIOS OC from scratch...

I reset the CMOS and reconfigured my BIOS OC settings again. Now things are worse—it's increased from 35v to 40v... because I forgot to enable input 2 for AVX, which caused a blue screen. I don't know what happens next...
🙁
Maybe it's not my day, and it's better to keep it without overclocking. I should have left it at 1.320v without making any changes after... Did I make any adjustments if I reinstalled Windows? By the way, my PC is new (only 2 days used). Also, I'm forgetting to mention that when I run benchmark programs like Cinebench or IntelBurnTest, the voltage goes up to 80-90v—it seems normal?
Thank you for your answers and patience (with me)

So far.
EDIT: Now it's down to 32c!
Maybe it needs some time to stabilize?
The voltage of 1.320V is significantly low for 5.0GHz, and I expect to see a blue screen at around 1.35V when Windows starts.
