Phisically unplugging monitor (and rebooting) did help. If i just disable monitor in manager, the memory frequency does not go below 2000 MHz. So if i wish to save power and temperature I would need to physically unplug the monitor. So this is not a bug? (sorry for posting 3 replys, didn't know about attachments) Is this still an issue? For what I understand it's firmware issue and depends on total monitor count. If there is only one monitor I can set gpu memory to either level (0 or 1). If you have more than one monitor plugged, than it's fixed to level 1 (2000 MHz). |

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.
