Hmm, with an other SD-card I've got the same problem.

 C L O C K    F R E Q U E N C I E S  

    arm   = 1200 MHz       pwm   = 0 MHz
    core  = 250 MHz       emmc  = 200 MHz
    h264  = 300 MHz       pixel = 0 MHz
    isp   = 300 MHz       vec   = 0 MHz
    v3d   = 300 MHz       hdmi  = 0 MHz
    uart  = 47 MHz       dpi   = 0 MHz

SD card = 50 MHz

 S Y S T E M    V O L T A G E S  

core = 1.3250V
sdram controller = 1.2000V
sdram I/O = 1.2000V
sdram chip = 1.2250V

@TheOldPresbyope The voltage can't be the problem. The values are default. This PI ist powered via the HifiBerry Amp+ with  a 18V 85W powersupply.

Very strange.
