AMD Ryzen 7000 Undervolting Yields Great Results with Temperatures
AMD Ryzen 7000 "Zen 4" processors can hit up to 95 °C at stock settings, with cooling most appropriate to the TDP level. This is because the PPT (package power tracking) limits for the 170 W TDP processors is as high as 230 W, and for the 105 W TDP models, it's 130 W. After reaching this temperature threshold, the processor begins to downclock itself to lower temperatures. Harukaze5719 discovered that higher than needed core voltages could be at play, and manually undervolting the processors could free up significant thermal headroom, letting the processors hold on to higher boost multipliers better.

Very strange that other "hardware enthusiasts" commenting here don't recall clock stretching tbh.
AMD has to set a value to make all CPUs stable under wide variety of conditions under all workloads. By all means tweak away, cause its cool and fun but randoms on Twitter and forums didn't discover something that AMD engineers didn't already know.
Why is that bad thing, considering most of them improve performance/compatibility or fixes previous bugs? Did you also forget AM4 socket is now 5 years old? And now tell mewhich Intel MB from 5 years back supports 12th gen:rolleyes:Think I misunderstood what you're saying :ohwell:
Or await verified proof perhaps that could work!.
And anyway, like system reporting software isn't ever wrong, they likely need to update hwinfo64 ASAP.
woah... I had no idea...
I feel like that should really be mentioned in the article. The final silicon may have a completely different voltage curve.
Of course different applications draw different levels of power and stress CPU in different ways.
And if you USED your pc for more than occasional gaming and 24hr trolling you would have seen it.
Would community grid, folding at home, at the same time, WORK, etc, does not equal light browsing and a bit of gaming.
Also on the last Intel chip I had, the USB3 drivers were full out of whack, sometimes they completely stopped working (all of the ports!) and required a hard reboot. That was back on a Z77 board though, and eventually I realized that it was the Intel drivers fault.
Also, because you had a problem with Intel USB 3 drivers, does not mean all Intel boards or drivers are crap either.
as for the topic of modern furnace CPUs:
Alder Lake runs surprisingly cool when you disable hyperthreading
probably going to be the same for Zen4, we'll see soon enough
Now, if AM5 was to be better than AM4 - then it would let you set SOC, IOD and CCD voltage while the CPU is still running. :)
As currently, the main thing that makes LGA1700 "better" than AM4 besides mild performance improvements - is the fact that to get that performance, you don't need to watch paint dry for several hours.
Several hours of boredom on top of already having to do memeory overclocking - but that part is the same for both AM4 and LGA1700, hee hee.
The BIOS updates always added new CPU support, and occasionally a bugfix.
Intel just require you to buy a new motherboard, free BIOS update included. For using 125W?
I'm not sure you thought that one through.
