Are you checking if PBO exceeds the specified maximum clock speed?

I thought Precision Boost Overdrive would never push the core speed past the chips' stated maximum.
The 5900X reaches a max boost speed of 4.8
However, HWinfo lists a max core clock of 4.950
I turned off PBO in the BIOS anyway, yet I’m still seeing this speed. It seems it only appears at startup.
I noticed this because idle temperatures are very high during idle but lower under load, which is confusing.
You'll need images from every bio page, assuming your motherboard supports overclocking or full-core enhancements.
Ah right, that would be Core Performance Boost. I'd forgotten about that.
PBO isn't performing that way; it's more like Precision Boost or the classic Turbo feature. Watch: https://www.youtube.com/watch?v=B7NzNi1xX_4
4.8GHz is the maximum default turbo speed. PBO can increase it by up to 200MHz further if cooling and voltage conditions are met. Typically, there are two options (don’t ask me why) for enabling PBO—one in the tweeker settings and another in the AMD overclock section. It can be confusing. In my Asus BIOS, turning one on or off doesn’t affect the other.
Yeah PBO is in the AMD Overclocking area and the misc, XFR section ... lol
I have just left them at AUTO which I understand is disabled.
I have a problem with the CPU not down volting at all. Always about 1.3V going to 1.4 too often.
I have discovered that NZXT CAM software is NOT compatible with Windows 11 at all. Which I Find laughable tbh .
Have you tried using Ryzen Master for any adjustments?
What motherboard model do you have?
For context, it seems we’re likely starting with default configurations across all settings, without any third-party tools. If that’s not accurate, let me know so we can move forward efficiently.
I hadn't altered the stock settings at all; I was using the F36 BIOS from Gigabyte for the X570 Elite Rev 1 board with a Kraken X63 cooler.
I haven't applied Ryzen Master beyond monitoring temperatures and core speeds, relying on HWInfo for temperature readings.
It appears to be boosting continuously even when idle. At full load, temperatures are normal at 71 degrees. After gaming or rendering, idle temps stay above 60 consistently. Cool boot temperatures are around 50 degrees.
I think the board supports three settings in BIOS: Eco, standard, and performance. To adhere to AMD and Ryzen recommendations for power limits, timing, and voltages, you should use the Standard mode. Performance mode increases these values, essentially reaching a gigabyte level of PBO. Most major manufacturers offer this, allowing them to claim their boards outperform others.
