SoC voltage 5800x3d on b550 taichi

hello, i just HAD to create an account after reading your post because I just ordered a 5700x3D and have been researching online on how to undervolt it through bios the same way I've done for my 5600 i've been using for the last couple years. is that 3.46 beta bios the one needed to unlock the voltage controls for the x3d chips? I really dont want to have to use PBO2 and set a task scheduler just to have it run those settings everytime. I'm even willing to run it stock as to not have to do that many extra steps of using PBO2 after running my manual undervolt without issue all this time. It was just a couple of settings in bios to tweak and the results were great.

So you can't run uclk:mclk 1:1 memory higher than 3800mhz, WHEA errors and etc. tried on 3.40 and 3.46beta bios. If you put 1.15v or 1.2v you will see this value in Ryzen Master, but in HWiNFO, A-Tuning and Zentimings it shows actual value 1.1v Why you did this, Asrock? you can set 1.2 on msi b450 board or any other vendors, but not on Taichi wtf?

Same here, worst experience ever I upgraded from an asus B450f strix gaming to an asrock B550M PRO4, to being able to use 2 NVME without cutting from x16 to x8 the GPU PCI-e. Now they ruined my 3967mhz ram OC profile because I can't rise vsoc from 1.1 to 1.125, it's absurd that they do that. I have the 5700X3D CPU.

I have WHEA 20 when trying to boot above 3800. I did a short google reading, looks like it is infinity fabric related.

After opening a ticket with ASRock support, they suggested to user Ryzen Master to check for VSOC. At least for my rig ... it works, if I change "SoC/Uncore OC Voltage(VID)", the change is reflected in Ryzen Master.

Did not get the chance to check if the value actually change and it has impact on infinity fabric stability, rather than just reading a BIOS value but with no impact whatsoever.

use ryzen master app

if it cant be changed even there, then your bios has it locked
