# Modify EDID, so my screens work at 61Hz
Trying to fix some what high power draw of RX 7900XT(to make its memory run cooler).




## XOrg
Put below config in `/etc/X11/xorg.conf.d/XXX`(also attached as file in /X11/XXX).
```
XXX
```
Then restart X session and from system settings set new resolution.



## Wayland(Gnome/KDE)
In this case, there are 2 options. First is to pass `video` kernel parameter(but it does not work for me) and other is to modify EDID so it contains addidional resolution data.
