You should be able to do this eg. on my R9 285

echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_le=
vel

cat /sys/class/drm/card0/device/pp_dpm_mclk=20
0: 150Mhz *
1: 1375Mhz=20

echo 1 > /sys/class/drm/card0/device/pp_dpm_mclk

cat /sys/class/drm/card0/device/pp_dpm_mclk=20
0: 150Mhz=20
1: 1375Mhz *

Though it will undo if you change modes or go into DPMS.
