| Summary | pp_dpm_mclk always on level 1 (cant set to level 0) rx 480 |
| Product | DRI |
| Version | unspecified |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | normal |
| Priority | medium |
| Component | DRM/AMDgpu |

I can't set memory state to 0 (300 MHz), it always stays at state 1 (2000 MHz).
If I set
echo "manual" > power_dpm_force_performance_level
echo 0 > pp_dpm_mclk
the memory clock stays at level 1, and I get kernel message:
[ 239.231304] amdgpu: [powerplay]
failed to send message 146 ret is 255
[ 239.995386] amdgpu: [powerplay]
failed to send pre message 201 ret is 255
The hardware is "SAPPHIRE NITRO+ Radeon RX 480 OC" and it might be BIOS
related, since some rx 480 users does not have such problem.
Using Ubuntu 16.04.2 kernel 4.13-rc4.
