This Ryzen 7 2700x is experiencing unstable high clock speeds and elevated temperatures.
So I own a Ryzen 7 2700x with an all-core overclock at 4.3 ghz. Sometimes when heavy tasks run, the hardware monitor displays it reaching up to 4.78 ghz across all eight cores for about two seconds before returning to the set value. This frequent fluctuation causes instability since the voltage is locked at 4.3 ghz for stability rather than a higher 4.7 ghz. I’m considering increasing the voltage or enabling auto-voltage, but right now it’s hard to maintain under 80°C with the current settings. If I let the voltage rise to keep stability, overheating becomes likely. Should I upgrade my cooler or simply keep the core clock locked? I’m using an MSI X470 gaming M7 AC motherboard, and the cooler I have is probably not much better than the stock Wraith Prism model. When it shows 4.78 ghz across all cores, it means each core is indeed reporting that figure.
Or that. I would certainly enter the BIOS and turn off any kind of boost or PBO/XFR settings.
Did you disable the TURBO setting in BIOS during the overclocking process? When you adjust your CPU cores to run at specific speeds, you usually need to turn off TURBO in BIOS, which is typically enabled by default for every standard CPU you purchase. It seems your CPU might be attempting to boost when it perceives 4.3 GHz isn't sufficient for certain demanding applications, and since the stock frequency is now used instead of the TURBO speed, it triggers a boost that pushes you up to around 4.7 GHz. I have been overclocking my CPU for years without reaching the frequencies I intended, so this is just my hypothesis.
This might be a glitch; your CPU isn't reaching 4.8 GHz. Many users face problems with the HW monitor. Try running hwinfo64 and selecting "sensors only."
And regarding the glitch, it isn't that I used the hardware monitor Ryzen Master command center CPUZ or checked the built-in performance section in Task Manager. I also notice it's unusual to be able to use XFR2 alongside my all-core overclock in the BIOS.
Are you sure your BIOS is current? Did you perform a fresh Windows installation when you first got the 2700X?
It's unlikely you're reaching 4.8 GHz. The highest recorded speed for an air-cooled 2700X is around 4.6 GHz.

it isn't maintaining a stable 4.8, it briefly drops for about 2 milliseconds before returning. This is probably because I didn't set a limit on my xfr2 profile, causing it to stay between 4.3 and 4.4 across all cores around 98% of the time during full load. It might jump to 4.7 when the system transitions under load.
and it doesn't always crash when the clocks go higher, but i've seen that whenever it does crash, it displays these clock speeds.
