It's not only it can, it must be done without rebooting, stuff in /sys are =
live
settings, even on installed distro, you must expect to lose them on reboot,
it's a fake file system, writing there does not write something on your hard
disk, reading and writing there is just reading and writing bits in memory =
with
a file system view for convenience.

Beware, there is a little mistake in Jan Ziak's directives (missing a leadi=
ng
slash before =E2=80=9Csys=E2=80=9D), this is ok:

$ echo manual > /sys/class/drm/card1/device/power_dpm_force_performance_=
level
$ echo 1234567 > /sys/class/drm/card1/device/pp_dpm_sclk

Do that *and do not reboot* or you'll lose the changes so you will never te=
st
them. The way to test them is to apply these changes at runtime and doing s=
tuff
without rebooting. If you reboot you'll lose the change.
