Does anyone know if ASRock is planning on adding SOC voltage manipulation in the next BIOS? Seeing how this parameter is so important to get a stable memory overclock, I don't see how I can get my RAM to run at its rated speeds without a higher SOC voltage. 

Thank you.

I doubt it, it's kind of odd we can just change it in Ryzen Master but not in the UEFI :(

I agree. Ryzen master has these option, but not the bios? Lol.

Each bios update has given more options, so let's hope.

I hope so as well. This is my first ASRock board and I'm super happy with it aside from memory OC.

Same. I've ran into issues overclocking but besides that, it's been a great board for how much I paid. It was retailing $65-69 USD and with micro-center combo it dropped 30 dollars Wink.  

This board is pretty feature rich for the price. I mean 2 m.2 slots? Some of the ATX boards only have 1 Pci-e m.2 slot, but this one gives you both pci-e and sata m.2. 

The growing pains for the memory seems to effect almost all brands, so fingers crossed! Hope you get it to work for you.

Hey guys
I have the AB350 Pro4 and am mostly satisfied with it
There are two ways of messing with the SOC voltage on this board (for now):

1. Ryzen Master - not ideal, but it works
2. If you overclock the RAM manually (i set my 32GB Corsair LPX from 2400 to 2933 @1.30V) from Advanced UEFI menu - AMD CBS; the board wil automatically overclock the SOC to a fixed 1.087-ish voltage for stability.

So the board is 100% capable of said voltage adjustment, and not having a setting in the bios is kind of user hostile to push the more expensive X370 boards over the "budget" B350 ones.

Hopefully the next uefi update will include the SOC voltage.

Cheers !

This is a result of OC'ing the memory. Ryzen does this automatically when OC'ing either processor and or memory.

Figured that much out, but this behaviour is not obvious in any way :)
BTW. CPU is at stock settings.

No. It's not obvious. That's why I piped in, to say so for those that weren't aware it does this.

In AMD CBS(forget which heading below it) do you have the option to set SoC voltage? There are some settings there that aren't available through the BIOS. Heck, you can just as easily OC the board from within it. I don't have a clue what this board has available under AMD CBS.
