It works perfectly with 3.81 X399 Fatal1ty and ASUS ROG STRIX 3090 flashed to latest FW.

I think the system feels better to handle several GPU loads at the same time, with less stuttering/slowdowns.]]> Tue, 29 Jun 2021 16:50:21 +0000 https://forum.asrock.com/forum_posts.asp?TID=19172&PID=88028&title=x399m-resizeable-bar#88028 https://forum.asrock.com/forum_posts.asp?TID=19172&PID=88027&title=x399m-resizeable-bar#88027 Author: crion

Well yes, when you disable CSM your boot disk needs to be set for UEFI boot (GPT layout).

This can be trivial but I needed a couple of tweaks to get the disk layout to change to GPT.

'sminfo' can verify if BIOS is in Legacy or UEFI.

run chkdsk before on disk so that you know it's in good condition.

Hello there,


I upgraded to version P3.81[BETA] to test the resizable bar thing with my VEGA64.

When i enable BAR option and disable CSM (mandatory) my nvme won't boot and I'm unable to use windows.

Has anyone ever experienced this ?

(if I deactivate the BAR option, everything returns to perfect normal)]]> Mon, 28 Jun 2021 21:03:24 +0000 https://forum.asrock.com/forum_posts.asp?TID=19172&PID=87998&title=x399m-resizeable-bar#87998
