I don't think that PBO includes XMP or undervolting and lifting power limits sure does not include them.
Z boards will often do much more than just lift PL and will do things that will void your warranty like pushing an all core turbo.
I was strictly speaking about PL and nothing else.
If lifting the power limit makes the CPU go "off-spec", then it would void the warranty as well. It'll come down to how each motherboard implements voltage delivery via VRMs power delivery. I'm also guessing VRM* efficiency becomes more important there and how they're controlling the cooling (of the VRMs).

So I don't have a straight answer for that one, other than "if the voltages go out of spec due to it, you do void the warranty".

Regards.

Oh yeah, thanks for reminding me, I forgot to block your ignorant persona. Bye.

Intel's power limit recommendations are just that ... recommendations. btw the system throttles down if the board heats up .. built in safety procedure.

It is irrelevant what you or Intel calls them. The fine print is clear: if the voltages are messed with on the CPU, your warranty is void. It doesn't matter how that happens.

Same for AMD.

Just saying, but you do know that to go up in clocks you do need more voltage, right? I'm not familiar with how Intel defines the "spec" for locked CPUs, but they do have a table for clocks per power limit on each. If the motherboard goes above that, then you're effectively using the CPU out of spec, no? Take the 12900 that has a lower PL2 compared to the 12900K. If the motherboard makes the 12900 go to the 12900K PL2, then that is out of spec, no? To do that, it will need additional voltage. I'm wondering if it's just a technicality, but at the end of the day, anything that bypasses power limits on the CPU is effectively an OC.

The locked intel cpu's stay in turbo boost mode longer when you choose to remove the power limits.

It's somewhat explained in this video.

That's a common misconception, maybe because a lot of mobos also enable MCE which IS OC, but lifting PL only allows software that uses more power than others to run at the same high clocks as software that uses much less power.
That's why mobo makers can get away with using PL settings of thousands of watts without having to worry about RMAs, the CPU stays within intel's max clocks for the CPU.

Intel also has stopped using turbo tables for years now for just this reason, turbos are adaptive now and having rigid tables would mean a lot of lost performance.

Raising power limits does not raise clocks above what is set as default by intel.

And yes, same applies to AMD and PBO only that AMD doesn't cover it in their warranty.

Not quite. That's the weird thing with Intel.

If the CPU is "specced" for a PL2 of, say, 200W, it implies all clocks and turbo behaviour will be within warranty if you don't go beyond the 200W and the voltages don't go over safe boundaries (somewhere in the spec these are mentioned as a recommended range, I believe). If a motherboard decides to enable the CPU to go beyond the 200W, be it a locked SKU or not, it can fall under OC if the clocks are pushed a lot higher. Think increasing BLCK, SoC voltage, etc, in order to attain stability at a higher power limit; be it user or motherboard trying to "enhance" the clocks.

It's not super clear cut, but at least they do make it explicit mentioning the voltages. What is clear to me though, is that you can still void the warranty as easy with Intel as you do with AMD; that's the point. Well, at least on paper. How either AMD or Intel would know, I have no idea.

Regards.
