Which BIOS you using for your Tomahawk? I am still on 126.96.36.199c for the B550 Tomahawk since I keep fTPM disabled and found a reliable way for the X3D single core boost to work. I just checked the X570 Tomahawk page and we have same BIOS releases unsurprisingly....the Beta Bios I was running for a similar MSI board already kicked the CPU in pants when I mistakenly enabled the CPU boost option in the firmware, but this was not stable.
Looks like Tomahawk owners are kinda left in the dust when it comes to newer beta BIOS' from MSI, but it isn't a big deal unless a real 5800X3D unlock arrives (doubtful).
I've been googling it and people said it was bad, with voltages still too high. I doubt enabling it on the X3D will do anything but increase voltages, but I am curious.If the board has the game mode option in the UEFI you should try it. Tomahawk B450 set my 5600G to 4.7GHZ all core, but all power saving features were still active. Max voltage was lower than OOB PBO.
Enabling PBO in BIOS with scalar of 2x does increase core clocks by a little bit, effectively overclocking the X3D by a miniscule amount. With my BCLK OC, enabling PBO scalar 2x creates boot instability which I find kinda interesting. Maybe I need a bit more voltage, which I can increase with MSI's tools.
We can even turn on Game Boost with Dragon Center. Not brave enough to enable it right now.
