Agree with this (1)


Not with this (2)


For (1), it's a customization that some motherboards BIOS offer that they sustain boost clocks for longer time by sustaining voltage for longer time. True that disabling this can sometimes help temps/stability, especially if you are also running AMD own PBO

For (2), "unrealistic" power limits are a myth. I have so far used a 5900X on an Asus B550 and a Gigabyte X570 board. The Asus one sets max PPT to 395W, the Gigabyte one 1200W. In both cases, the chip automatically limits itself to about max 200W with PBO on, all Auto. In other words, motherboard limits are just what the motherboard is capable of providing, the CPU will not use more than what it needs. How much will it use is a combination of what limits you give it and cooling. If you can cool it infinitely, then it will boost to it's max infinitely. Basically that's it.

If you don't want any overclock, I suggest still turn on PBO, set the PPT/TDC/EDC to the default values (these can be Googled), leave everything else auto, and use curve optimizer to undervolt, it will certainly help temps.
Well, on theory it should reconcile to the thermal limits. However, we have cases of whea errors because of firmware/hardware stuff. You might get lucky with default settings from motherboard maker, not everybody is lucky.

The point is in a typical desktop setting, the CPU never hits or even approaches those limits. So if you're getting WHEA errors, I highly doubt it's because of the mobo power limits, which in the case of PBO is specifically the 3 parameters of PPT/TDC/EDC. Other parameters such as boost scalar, max boost override, max temp can also be controlled via motherboard but those limits are capped at the same as AMD's own, i.e. max scalar 10X and max boost override 200MHz.

Enabling PBO and manually setting limits to the default, ensures you are getting the stock out-of-the-box limits + the benefit of undervolting to improve temps. Improvement of temps also helps with stability, since the CPU clocks don't yo-yo between hitting the max capability of your cooler and what it has the potential to do. In the Intel camp, there's the phenomenon where the i9 10900K hits a higher max boost than the 10850K but overall sustained clock is lower by about 100MHz because that's exactly what happens.

Point is, motherboard default is actually not at the appropriate settings. And they are unrealistic considering AMD official spec. The normal user will not think of googling the official values and manually set them. So many issues with Ryzen3000/5000 arises from this.

Lol, I thought that's the point of these forums, as are many avenues like other forums and Reddit. What's the point of discussion if we don't learn anything? Well, I'm just sharing from my experience and what I learn elsewhere as well, a (free) way to improve performance. PBO is baked into Ryzen, you paid for it anyway so why waste it. Anyway, to each his own, your rig your call. I put the info out there, it's for anyone who reads to do what they wish with it :)

Reference image for what I was referring to earlier. This is a steady state after 15 min of 100% load. I remember wrongly, it's not 4.6 GHz steady but 4.5 GHz. In other words, by undervolting and playing with just the PPT/TDC/EDC, I get a constant boost of just 100MHz below the max stock boost of a 5600X. The CPU at this point is not thermally limited but power limited, hence the 100% of PPT/EDC. CPU power at this point is 73.5W, 8.5W higher than the 65W stock TDP of the 5600X and temperature is steady at 70C. My radiator fan curve is 70%/70C to 100%/75C, so this is also not pushing the limits of my cooling potential.

Now this is very different from overclocking, because with PBO it is not a static 4.5 GHz. The CPU is still able to reduce clocks or even set cores to sleep when cores/threads are not loaded. Btw do not be alarmed at the red colors of PPT and EDC, the color scheme simply is applied according to how close the values are to the limit. Even at stock, these will show red when the CPU hits the (low) limits. Undervolting plays a big part since it literally reduces the heat produced at the same clock speed as a non-undervolted core. I only apply a modest undervolt of -10 for preferred cores and -15 for the rest, which translates to a range of -30 to -50 mV preferred cores and -45 to -75 mV for the rest. This is the other genius part of PBO undervolting - it doesn't apply a fixed offset but a range, allowing the CPU some wiggle room in terms of stability. I run this CPU at 100% load, 4.5 GHz, 70C for a full 24 hours and nothing is going wrong, no crash no WHEA no whatever. Pretty sure it'll go for days without issue. I even have room on my fan curve to cool the CPU even further if I want to, but higher speeds = more noise and I think 70C is very decent and well within the limit of the default thermal throttle temp (95C).

Okay, I think this is a lot of info on PBO for Zen 3 already. Again, it's just for reference. Whatever anyone does with their CPU is none of my business, just sharing some information which might be useful for someone.

Seemed like updating the hwinfo to 7.02 works, was only on 6.40 previously... max temp running heavyload with hwinfo was only 77.6. Idling between 33-37degC room temp. Down to 31degC when i on my AC

Was playing abit of RDR2 last night too. Max temp only hitting between 58-62degC. Guess this issue is "resolved" for me now. Thanks all for the advice.

Congrats, glad you solved the issue!

So it wasn't even a hardware problem to begin with but an app-specific one. I'm gonna guess it's a memleak crash, but it's just speculating. End of the day, good to know that the hardware is doing fine.

anyone got any advise on Asus ProArt B550-CREATOR?

Is it just because of better I/O? or it claim of superior 24/7 of quality, stability and compatibility?

thanks

I had the USB issues a few months back. Have been keeping updated with all BIOS release, and currently have no such issues anymore. My previous board was Asus ROG Strix B550-I with BIOS 2201. Current board is Gigabyte X570 Aorus Master with BIOS F33i. My keyboard/mouse are all using Logitech Unifying receiver. Both boards are fine, no USB dropout issues anymore.

hows Windows Update 20H2 doing for you guys~?

it seems to re-recognize my USB ports (mouse and keyboard and maybe more).

then there's 2x (gradual) freezes and 1x blue screen before reaching the login screen.

currently on Asus B550I.


prior to that the system is relatively stable, was able to complete my 70+ hrs AC Odyssey.

That's quite concerning. In my experience with the Strix B550-I, I never had a freeze. Only once I changed RAM timing forgot to increase voltage then system cannot POST, must reset CMOS. Could there be some component that is unstable, e.g. RAM or GPU?

yeah it's weird.

5600X (Undervolted -10), G Skill Flare X 8GBx2, ASUS B550I, EVGA 3070 (Undervolted)

i feel like my motherboard's driver got reinstalled or something..
the first boot after 20H2, ASUS ArmouryCrate actually loaded up (which usually only happens on a fresh install)

then again, all these were on Saturday. So far.. havent encounter it 🤞🙏

If i were to compare 20H2 to version 2004 which i was using previously. i prefer 2004 lol every update windows 10 die a little inside

Those with USB issue got it sorted out with new bios firmware?

i am still having random issue of my ps4 controller using with inputmapper disconnecting randomly during gaming, have to restart the whole pc if it happens. however i think that this might be the app issue as the app was last updated in May 2020. Already updated to the latest bios from asus.

is it the 1.2.0.2 (or something?) patch?

yes.

TUF GAMING B550-PLUS BIOS 2201
"- Update AMD AM4 AGESA V2 PI 1.2.0.2
- Fix USB connectivity issue

Also updated my chipset driver to 2.13.27.501 downloaded from AMD website.
