Can someone help me with my GPU OC on Fedora 31?

First of all, I’m sorry if the forum is not for support but I’ll go ahead ask for help. I was happily using overdrive on my RX 560 and made some changes to grub and it doesn’t work anymore. I made changes to grub with grub-customizer and then ran the grubby command to add the parameter amdgpu.ppfeaturemask=0xffffffff to the kernel but even though these steps have worked before it is not the case anymore. I’m using xxmitsu mesa repo btw.

It worked after I set the parameter alone and the other parameters on another variable. If together I was sais to put it last.

GRUB_CMDLINE_LINUX=“resume=UUID=90416566-7972-4322-96dc-722d764f06cb rhgb quiet splash”
GRUB_CMDLINE_LINUX_DEFAULT=“amdgpu.ppfeaturemask=0xfffd7fff”
