Running at a significantly lower voltage is identical to overclocking without enough power.
Yieks wasn't aware of that... Are you familiar with the suggested vcore voltage for an I7-9700? I usually run it at 1.25, which was just the lowest I could afford. On a 1.22 core it didn’t even boot, so I think 1.25 is a bit low and might cause issues. I also recall the stock voltage was higher—around 1.45 for that CPU. Do you know what voltage range would be ideal to avoid problems?
Sorry, I can't handle that. Not because of my behavior, but because the latest Intel part I have is a 3770K.
If the newer components resemble the old ones, 1.35v should be sufficient for all conditions. Usually 1.25-1.3v works well. I'm not completely sure about the updated parts.
For a reason the auto was set to 1.45V, which seems too high for a non-K chip. I lowered it to 1.25 but still noticed some performance drops. It's running at 4.7GHz.
I’d just let it be, allow whatever happens. You won’t hurt it. 4700 is still a fast pace. Not too long ago that number was the limit—or nearly it—especially if you think of comfort. Don’t let it rise too high. They can handle the upper 80s and 90s just fine. If I had it, I’d avoid pushing it beyond that. I’d invest in a decent heatsink, something solid but not overly flashy. There are plenty of good options out there.
