Umm, Asrock B450 boards have supported Resize Bar (also known as Smart Access Memory) for a long time now.

You have to disable CSM, and then enable "Above 4G Decoding" + "Resiable Bar."

re-bar is supported on your mainboard since agesa V2, that would be bios version 4.40
if you dont see it, then you dont meet minimum requirements to enable it
requirements:
ryzen 3000 or better (not including 3400G/3200G)
above 4G decoding needs to be enabled
CSM needs to be disabled
operating system needs to be installed in UEFI mode on GPT drive
GPU RX 6000 or better or nvidia RTX 3000 or better, but on nvidia only like 30 games have enabled rebar due to performance issues]]> Tue, 12 Sep 2023 23:10:26 +0000 https://forum.asrock.com/forum_posts.asp?TID=26589&PID=107515&title=resize-bar-support-for-b450pound#107515 https://forum.asrock.com/forum_posts.asp?TID=26589&PID=107514&title=resize-bar-support-for-b450pound#107514 Author: radry

So some B450 Mainboards (Asus) support resize bar with a Ryzen 3000 CPU via Bios update.

Will Asrock B450 Boards (specifically the Fatal1ty B450 Gaming-ITX) support it too some day?

I noticed a beta bios 8.01 which seems like a large Version jump from the current 5.20 when it only updates AGESA. There must be other, hidden changes or not? Does it maybe include resize bar?]]> Tue, 12 Sep 2023 22:00:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=26589&PID=107514&title=resize-bar-support-for-b450pound#107514
