https://bugzilla.kernel.org/show_bug.cgi?id=207693 Bug ID: 207693 Summary: amdgpu: RX 5500 XT boost frequency out of spec Product: Drivers Version: 2.5 Kernel Version: 5.6.12 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: 0xe2.0x9a.0x9b@xxxxxxxxx Regression: No Hello. A Navi GPU (model: MSI RX 5500 XT Mech OC 8G) installed in my machine defaults to 1885 MHz in Linux as its maximum frequency. However, in Windows 10 the GPU's maximum observed operating frequency is 1845 MHz and the manufacturer's website states that the boost frequency of the GPU is 1845 MHz. $ cat pp_od_clk_voltage OD_VDDC_CURVE: 0: 500MHz @ 730mV 1: 1192MHz @ 774mV 2: 1885MHz @ 1112mV Sometimes, the printed voltage is 1107mV. https://www.msi.com/Graphics-card/Radeon-RX-5500-XT-MECH-8G-OC Windows uses 1845MHz@1112mV. If Linux is running the GPU at 1885 MHz shouldn't it also increase its voltage in order to decrease the probability of hardware errors? -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
