Does PBO affect the CPU?
Does PBO affect the CPU?

I hadn't encountered that piece before, yet it still clarifies quite a bit about the actual function of Scalar settings.
A few observations are being highlighted:
"In premium motherboards, XFR2 is enabled by default (though this may vary by manufacturer), whereas in lower-end boards with insufficient VRM capacity, it could be turned off or restricted when paired with power-hungry processors like the Ryzen 7 2700X."
What about users who don’t rely on a 'top-tier' board, where all features remain active despite having powerful VRMs?
And regarding PBO, there’s a secondary setting named Precision Boost Overdrive Scalar (PBO Scalar) with a scaling factor ranging from 1x to 10x.
This introduces additional impacts, such as increased heat production in both the CPU and VRM due to higher current and voltage, leading to elevated temperatures on the CPU.
For example, on a Ryzen 7 2700X running single-core tasks like web browsing, the voltage is typically around 1.44–1.5V. In gaming, it drops to about 1.39–1.43V, and during intensive productivity tasks it reaches roughly 1.35–1.38V."
(Referring to what standard?) Scalar 1? What would the results be if it were disabled? Also, it remains unclear how this relates to the Ryzen 3000 series, as the article is quite outdated.)
Applying PBO Scalar at 10x would likely shorten the chip’s lifespan (which is expected), but it’s hard to quantify exactly. I’ve tested PBO for several months and find it among the most attractive features Pinnacle Ridge provides.
I concur that pushing your system harder can affect silicon longevity—this is undisputed, even if using it at all reduces lifespan. The main argument here is difficult to verify, though. Previously, better cooling was emphasized as crucial. Overall, the recommendation leans toward using it cautiously, given the positive tone of the discussion.
Also, I should note that the post I mentioned earlier was essentially a rephrased guess from another source, and I’m still uncertain about its specifics."
It appears the warranty details don't reference PBO or overclocking beyond what's already noted. The only clear point is the vague warning about improper use.
AMD’s product warranty excludes damages resulting from overclocking, even when enabled through AMD hardware or software. PBO voids your CPU warranty, though physically applying LN2 and leaving the device as-is does not cancel the warranty. From an AMD video, "Discover how updates to Precision Boost Overdrive on certain AMD Ryzen 3000 Series processors introduce a new automatic overclocking capability that enhances performance."

Does not imply that in AMD literature or simply because you're reading it that way changes its meaning.
As I mentioned before, AMD intentionally avoids using the term 'void' when talking about their warranty and PBO.
EDIT add: And yes, I agree the 'automatic overclocking' feature is often seen as overclocking, which I noted earlier. However, you can still enable and adjust PBO and SCALAR without activating automatic overclocking. In my experience it doesn't function properly, likely due to something MSI did in their BIOS.
My 3700X with PBO and some tweaks gives 5135-5155 MT and 511 consistently ST. The 519 score for your CPU indicates it's maintaining a higher clock under light load, which is typical for a 3800X but I'm unsure if it's suitable for a model reaching 4600 on single-core boosts. My higher MT scores suggest the chip isn't reducing clock and voltage as much when handling the load, so it should stay cooler. I run three tests with CB20; 5155 is the score from the first run, and 5135 from the third.
From AMD's website, "AMD’s product warranty does not cover damages caused by overclocking, even when
overclocking is enabled via AMD hardware and/or software."
From an AMD video,
"Learn how updates to Precision Boost Overdrive on select AMD Ryzen 3000 Series processors provides an all-new automatic overclocking feature that can give you higher performance. "

One Click Overclocking
Making Precision Boost 2 even better
Precision Boost Overdrive (3) uses your motherboard’s robust design to boost clock speeds higher and longer, and lets you overclock (4) at the touch of a button."

(3) Precision Boost Overdrive requires an AMD Ryzen Threadripper, AMD Ryzen 5 3000, AMD Ryzen 7 3000, or AMD Ryzen 9 3000 Series processor and a motherboard compatible with one or more of these processors. Because
Precision Boost Overdrive enables operation of the processor outside of specifications and in excess of factory settings, use of the feature invalidates the AMD product warranty and may also void warranties offered by the system manufacturer or retailer.

(4) AMD’s product warranty does not cover damages caused by overclocking, even when overclocking is enabled via AMD hardware and/or software. GD-26.
AMD consider PBO itself an auto overclocking feature, as stated by AMD above in there video. PBO boosts multi core performance. It is made up of AMD hardware and software. Auto-OC is different from PBO but still appears in the PBO settings. Both features are overclocking the cpu, thus reasons for voiding your warranty.

What Will Void a Warranty?
If you overclock using PBO, its a reason for voiding your limited warranty. Hence
,
the term void is used correctly. There is no need for AMD is state void, its a legal outcome of breaking your limited warranty and rendering it
invalidated
.
Void (law) - Wikipedia
en.wikipedia.org
In
law
,
void
means of no legal effect. An action, document, or transaction which is void is of no legal effect whatsoever: an absolute nullity—the law treats it as if it had never existed or happened.
invalidate
. to take away the

force or effectiveness of; to annul, as a contract.

To
invalidate means
to cancel something or make it
void
, as if it never happened. In
invalidate
you see the word valid which
means
true or correct. When you
invalidate
something you are making it less true, less official, or less correct.
