| Summary | RX460 Memory clock stays high until card is "used" |
| Product | DRI |
| Version | unspecified |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | normal |
| Priority | medium |
| Component | DRM/AMDgpu |
| Assignee | dri-devel@lists.freedesktop.org |

linux 4.11.4 I use the IGPU on SKL and a RX460 as a dedicated card. In XOrg i turned autobindgpu, autoaddgpu off and singlecard on. with fb fbcon=map kernel parameter i map the linux ttys to different cards. the way i switch to the AMD card is to vt switch and then change the input on my monitor. this works fine and lets me login via agetty and launch a new xserver. One thing i noticed is that until i actually do that the memory clock of the card stays high (17xx mhz?) which makes it 5-8°C hotter and probably uses more power than it needs.
