When i overclock it up to 47, it requires about 1.40 core voltage to avoid crashes during booting or stress tests. This seems quite high compared to similar setups on YouTube and forums where voltages are around 1.330 or lower. Temperatures are normal, reaching up to 64 degrees Celsius during stress tests, and performance in Battlefront 2 is roughly 60-65. Any advice would be appreciated. Thank you.

The discussion focuses on silicon and the silicon lottery. It mentions achieving a score around 4.8 with a 6700k chip at approximately 1.370V. The advice includes checking VCORE in the HWmonitor software, ensuring voltage settings match between Windows and BIOS, and using manual voltage if needed to exceed 4.6. It also asks about safety concerns of higher voltages above 1.42V despite lower temperatures.

It's all about silicon, right? You've probably heard about the silicon lottery. I think I could hit 4.8 on my 6700k around 1.370V. Also, double-check the VCORE in your HWmonitor (software) on Windows—based on what I remember, your motherboard lacks LLC control that stops voltage drop. Compare the voltage in Windows with what you set in BIOS. If you want to go higher than 4.6, consider using manual voltage.

You're definitely using manual voltage, which is why it crashes when too low. One question: is it safe to have higher voltage than 1.42, even if temperatures are under 80? Thanks for your quick reply. I don't think this processor came out of the lottery.

Comparing the voltage in Windows and BIOS is recommended. Manual voltage is suggested to avoid crashes when it drops below 4.6. It's noted that higher voltages above 1.42 are not necessarily dangerous if temperatures stay below 80°C, though the user prefers keeping temperatures low for everyday use.

What I would consider if I were you was the risk verses reward... At 4.8 you are running higher voltage to get stable... Your temps are fine and such, but what are you temps and voltage at 4.6? I bet you'll find that it is significantly lower and I think the difference would be negligible between 4.6 and 4.8...
Personally I run my 6700k at 1.25 at 4.6... It can do up to 5.0, but I have to jack the power up to 1.45 to do it and I'm not comfortable with it... On a day to day basis...
Now, for benchmarking just for bragging rights... That's another story!
