Well, This Beta bios (6.61) clearly doesn't boot up my new Ryzen 5700g even if it has Cezenne support in it.AsRock has experimental BIOSes out for Vermeer support. It appears they are 22.214.171.124 Patch C
Do you cross flash AB350 Gaming-ITX/ac with X300 BIOS? I don't think if I understand this correct... If you cross-flashed and it works, than I will gonna upgrade soon. Do you have any peripheral issue?@EUA - I've already confirmed the 5600G works on 1.60 bios.
Later today im getting a 5700G and I'll confirm if that works on 1.60 bios as well.
And for the X300 desk mini bios make sure you're using bios from here:
AMD AM4 Socket CPU, - Cezanne, Renoir, Picasso, Raven Ridge, up to 65W, - Support MAX Height ≦ 46mm CPU Cooler<br />Supports Overclocking Option with X300<br />High-Speed DDR4-3200MHz Memory<br />Dual Ultra M.2 (NVMe), - M2_1 M.2 (2280) – PCIe Gen3 x4, - M2_2 M.2 (2280) – PCIe Gen3 x2/x4<br />2...www.asrock.com
Please let us know your results! I have the exact same board and am considering a similar APU build with the Ryzen 5 5600G.New B450 ITX bios available. Cross-flashed and Successful boot with Ryzen 1700. Will test if it works with 5600G. There are some rumors about if AGESA 126.96.36.199 should lifted the ban...
Don't even tried by borrowing the CPU from friend because learn somewhere that 188.8.131.52 bios still has a B300 lock for Cezanne cores. But probably it will work with 4600G...Please let us know your results! I have the exact same board and am considering a similar APU build with the Ryzen 5 5600G.
On another note, I know the Asrock AB350-ITX actually has HDMI 2.0 ports (not 1.4 as advertised). Do you know if the board will support two displays (one 2560x1440, one 1920x1080, both at 60Hz) with an APU?
Let's see if they will include the B350 boards in the 184.108.40.206 release. It's still another full month away before its release.Even Asus are coming out with this, though confusingly omitting B350 boards: https://www.techpowerup.com/292983/asus-announces-bios-support-for-ryzen-5000-4000-processors
