Ryzen 3000, amd publishes new beta bios that fix the boost clock
Table of contents:
A new beta BIOS has been released and promises to improve the 'boost' frequencies of Ryzen 3000 processors. This new BIOS was tested by the people of Tomshardware and it seems that it works, at least, with the Ryzen 7 3700X, although there are still deficiencies, probably due to being in a Beta state.
Testing with Ryzen 7 3700X
Tomshardware plots the frequency of the eight cores on the left axis and the temperature (red line at the bottom of the graph) on the right axis. The Ryzen 7 3700X processor runs at the factory settings and a Corsair H115i heatsink at full speed.
The first graphic shows the behavior of the CPU with the latest official firmware of the MSI X570 Godlike motherboard. Here we can see that the Ryzen 7 3700X reaches 4, 375 GHz. Although this does not reach the 4, 7 GHz nominal power of the 3700X, it is a relatively small margin. However, the deficiencies vary depending on the quality of the silicon.
Applying the new ComboPI1.0.0.0.3ABBA AGESA firmware, and as you can see, the Ryzen 7 3700X now reaches its 4.4 GHz rate easily and stably.
Testing with Ryzen 9 3900X
Our tests with the Ryzen 9 3900X do not show the overall improvement that was expected, which may be due to the beta nature of the BIOS.

Here we can see the Ryzen 9 3900X with the old code AGESA ComboPi1.0.0.3ABB. This is the latest firmware released for the Godlike X570 motherboard. We can see that the chip reaches 4, 575 GHz during execution, with the workload migrating between the cores during the test. That's just 0.025 MHz below the chip specification, but many users have seen differences of up to 300MHz, and more.
With the new firmware, the chip peaks at 4.625 GHz during the first few moments of testing. The chip is tuned at 4.6 GHz during LAME testing, and then runs at 4.55 GHz during the POV-RAY portion of the test. Interestingly, the chip falls to a lower threshold during Cinebench at the end of the test, reaching just 4.425 GHz during that portion (yellow lines).
While we see a higher peak gain, the chip runs at a lower frequency for most of the test. This may be due to a bad firmware implementation for this particular motherboard, or it may be due to the beta nature of the BIOS. We will have to wait until the new final firmwares to know if this is definitely fixed in the Ryzen 3000 series.

AMD has changed the product specifications of all Ryzen processors. The Max Boost Clock is now properly explained.
Amd would have lowered the frequencies 'boost clock' in ryzen 3000
AMD had been too aggressive with the boost clock, and with a view to improving reliability, those frequencies would now have been lowered.
Agesa 1.0.0.4 improves ryzen 3000 'boost clock' speeds
MSI confirmed that AMD had AGESA plans extending to AGESA 1.0.0.7, which means there are even more improvements on the way.
