nice to see my card dominating in performance per dollar

I've followed that and verified by grub boot entries. amdgpu.ppfeaturemask=0xffffffff amdgpu.dc=1 amdgpu.dpm=1
For some reason my card is stuck on the 300mhz entry. I've used watman-gtk (hence ppfeaturemask) to verify. I haven't tried to apply any wattman settings as I don't want misconfigure anything further. I'm assuming on default values clock gating should work out of the box.
When using the feature mask boot parameter clocks are stuck at 300MHz on 4.18
Thanks to a good fellow on these very forums, the workaround seems to be :
echo "1" | sudo tee /sys/class/drm/card0/device/pp_sclk_od
echo "1" | sudo tee /sys/class/drm/card0/device/pp_mclk_od
And voilà , your card should be running normally.
You can than overclock through p-states:
FYI I've been able to push my RX 470 to 1350MHz/1750MHz at stock voltages.
Didn't try to go higher yet.

Is it not time to benchmark COMBOS?
Freesync + AMD vs G-sync + Nvidia
And their combo price range and performance per dollar in combos
At least until there will be crossed drivers, if they ever be
As Freesync monitors are cheaper ...
would not be AMD GPUs in advantage when you are going to purchase a combo for gaming
in 1080p as 4k is still not for gaming?

In case you missed some of the random information that came after. 4.19 fixed the clock gate issue for me. i had to remove the featuremask as it was causing graphical issues. But the wattman output now seems to suggest a different mask to what I was using.
please have a look @ amd-staging-drm-next
