Resizable BAR / SAM on Zen 2 (Ryzen 3000/4000) on X570 Taichi

[Figo]

Looks like ASrocks new 4.0 Bios has unlocked SAM for older Ryzen CPUs

Decent wee performance bump on the RX 6800 - not bad at all for a bios toggle!

Interesting. It is the same AGESA as MSI ones. I don’t have AMD GPU so can’t tell if that options is available.

Do you know if this will come to B450?

Do you know if this will come to B450?

I believe so yes via a bios update first.
