Asrock AB350M Pro4 with Asrock AB450M Pro4 bios

[Final_Fighter]

So if you saw my other thread you will understand the logic behind what ive done here. so straight to the point, the flash works so far. ive tested the usb ports, the sata ports, m.2 slots, lan port along with the audio outputs. ive put it threw my normal rounds of prime95 for stability and other random tests. it seems to hold my overclocks on both the ram and cpu just fine. all sensors report properly as best i can tell. the OC tweaker tab and H/W Monitor tabs have some more options that are not on the ab350m pro4 bioses. i dont have pics of the bios screen yet but will get some here shortly. (edit: the pics of the bios are uploaded.)

Warning Warning Warning

This can brick your pc and there does not seem to be any benefits to doing this that i have found so far. Flash at your own risk!​

the images below are from my other thread but are completely relevant. the process is the same.

First and foremost, set your bios to its defaults. then proceed ahead.



So first step i did was download AFUWINGUI.exe V5.09.02.1384. i downloaded it from the Asrock website HERE, its included inside the Windows flash method 3.40 bios, go ahead and extract it. then head over to the bios section for the Asrock ab450m Pro4 and grab the bios for that board. extract it were you can find it. after that go ahead and open it up AFUWINGUI.exe



Next click "Open" and select B45MP4_1.ROM. after that go over to the "setup" tab shown above and select the boxes as shown.




Once thats done slect the "Progress" tab and click "Flash". after it reads all the blocks the above window will appear. make sure to read it then press "ok" if you are ok with potentially screwing your board up.




After the program does its thing it should look like the above.

if i have any problems ill let you guys know but feel free to test this at your own risk and report what you find.


Findings:

It seems the fan controller maybe different and i was not able to change the fan speed on my fans

Findings:

It seems the fan controller maybe different and i was not able to change the fan speed on my fans. all fans would run at 100%.

with this bios i was now able to adjust the soc voltage in ryzen master only. the bios soc voltage does nothing but in windows i can see a change in the soc voltage using software such as hwinfo64. i have not tested to see if this provides higher overclocks on the ram or cpu yet.
