            Bug ID: 105664
           Summary: AMD HAINAN (Radeon R5 M330) Clock frequency is 750MHz
                    while it is supposed to be 1030MHz
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: yassine10suno@gmail.com

Kernel source: /drivers/gpu/drm/radeon/si_dpm.c line 2985:

                          max_sclk = 75000;

  instead of

                          max_sclk = 103000;

Why is that? I changed it and rebuilt the kernel, and I can say that
there are absolutely no issues when using the 1030MHz clock, **which is the
default frequency this GPU is designed for**.
