@Lost_N_BIOS no I just needed to confirm something that I suspected as either Biostar or AMD BSing over, which is to say Precision Boost working only on X470 chipsets. No replies from Biostar today so far I can imagine some of them might well be scrambling for solutions and answers right now.

PBO is enabled out of the box for nearly all X370 boards.

...Except for the boards manufacturers are too lazy or incompetent to update ;) I knew what was being said was BS but I wanted to make absolutely sure with someone who uses a Zen+ CPU to eliminate all scenarios just in case there were some situations I wasn't aware of where PBO didn't work.

So you take X470 PBO and put in there? If not, how is it working for Barisuraz?

i haven't fiddled around with the fan problem but stumbled across an other problem which i have with the non moded bios as well. sometimes after wakup from hibernate and suspend th clock is stuck at ~550MHz. the only way to fix this is a reboot. do you know if that's an issue of the bios or a windows energy profile issue?

Simply put, the core of all X370/X470 bioses are same. It's the AGESA. Per AMD spec, PBO is only required to be enabled for 4xx boards. But as they share the same codebase, it can be enabled pretty easily on 3xx series boards. In fact, lots of mobo manufacturers have already enabled it for their 3xx lineup but Biostar is lacking as always.

Yep thats it in a nutshell AFAIK PBO works best with Zen+ CPUs though which is why I asked bar to check the feature out.

Sorry @ket I thought by the way you asked him, that you figured out something and send him another BIOS to test. Since it's working for him, but not you, what does that mean, some compatibility issue with your CPU type but not his?

@Lost_N_BIOS No, PBO only works with X series CPUs.

I gotcha now! Should be enabled for all CPU's, who does AMD think they are, Intel?

It is weird only being used on the X models but its likely more just a suggestion in AMD documentation that manufacturers have taken too literally.

I bet you are right, I wonder if maybe we can fix that?

Probably something that can be changed I never tested it on my 1700 though so don't know or not if once the option is exposed and enabled if it'll just work on any CPU or not.

@ket @Lost_N_BIOS : thanks for your replys but i cant figure out why the fans don't behave like in the non modded bios. as soon as the temp reaches 32 °C all my fans go fullspeed. X37AG807.BST is working without any issues regarding the fans for me. but there is so much stuff missing like custom p-states, memory resistance, etc.

would it be possible for you to mod a bios for me the the "old" fan module which is found in X37AG807.BST? that would be really great!
