Overclocking is running a CPU at higher clock speeds than advertised. If you just change PBO limits, it never goes beyond what AMD knows their silicon can hand

Overclocking is running a CPU at higher clock speeds than advertised. If you just change PBO limits, it never goes beyond what AMD knows their silicon can handle, and what is sold to the customer. Individual cores might already be boosting to those clock speeds over short intervals. You're just allowing more cores to do that and longer, within your configured power limits. The expectation here is thermal throttling, not an unstable system.

  PBO allows overclocking[1]. But it mainly allows you to configure other stuff, liking raising/lowering certain limits, that are not overclocking. Changing these values will not make your CPU reach voltages it wouldn't otherwise have reached, nor will it make your CPU reach clock speeds it wouldn't otherwise hit. It will however make your CPU draw more amps and use more watts to sustain clocks for longer than normal and on more cores at once. Allowing here means that in the typical motherboard you'll have to change PBO from the default "Auto" to "Manual" to see these settings. Where do terms like "undervolting", "overvolting", "setting TDP" even fit in your vocabulary if you insist everything is to be called "overclocking"? These terms should be literally self-explanatory. [1] But only technically, because for some reason the AutoOC feature is found in the PBO menu on motherboards, even though AutoOC is not part of PBO. They are however typically marketed together.

  That's not a very technical article, though. Are you calling this explanation completely wrong?: https://www.gamersnexus.net/guides/3491-explaining-precision-boost-overdrive-benchmarks-auto-oc https://www.gamersnexus.net/guides/3491-explaining-precision... This is someone who should really know what they're talking about. > What is important to note is that PBO only affects these three power limits. The effect on CPU clock speed is indirect, and PBO will never boost the CPU past the advertised clocks. I think it's fair to say adjusting power limits falls under a deliberately broad "overclocking" umbrella, but it's not really overclocking, and doesn't require you to do the effort part of real overclocking. > This is patently false! I don't know where you got this idea when I literally just quoted AMD saying it raises clocks past factory specifications! The part you quoted doesn't have the word 'clocks'.

    > The part you quoted doesn't have the word 'clocks'. If you don't know clocks is slang for clockspeed, you're out of your depth. So just stop talking. > This technology can improve your PC’s performance by raising clockspeeds And you're saying that technical documents from AMD don't know what they're talking about (it's a technical document. It's a technical article.) But GN, the kings of stating guesses confidently with the worst understanding of statistics I've ever seen to an uninformed crowd do? Please. I don't even care how you cope with PBO being an overclock anymore, call it a "raising clock speeds over stock" if it helps you sleep.

      > If you don't know clocks is slang for clockspeed, you're out of your depth. So just stop talking. I phrased that badly. I was talking about the second quote there. It's a little bit subtle. The first quote says it will raise clock speeds. The second quote says it will operate outside of specifications. But nowhere does it say the clock speeds will be outside the specification. It's raising the power limits outside the specification so that it can raise clock speeds inside the specification. > And you're saying that technical documents from AMD don't know what they're talking about (it's a technical document. It's a technical article.) If you can quote me something from AMD that specifically says PBO (not AutoOC) raises the maximum clock speed above the number you can boost to within spec, I will admit I was wrong and apologize. But the page you linked doesn't say that.
