AMD AGESA version 1.0.0.4
AMD AGESA version 1.0.0.4
No one has updated the latest AGESA yet. It seems to maintain the same boost performance as before, around 4.1Ghz for your 3900X. You're testing with Cinebench R20 and AIDA64 while using Ryzen Master. The default settings are applied, and no autoOC is being used. Your Gigabyte motherboard is in use.
Check if the single-core boost is verified using a Cinebench single-core benchmark.
Check if it's intended for Beta testing or an official launch. Also, confirm whether there are any voltage variations observed.
On Gigabyte boards, the latest BIOS is officially released, not just a beta version.
It seems voltages are handled differently now. Besides faster clock speeds and better performance, there are other changes you've observed.
