It works that way on my other boxes. On this specific box microcode_ctl is not activated automagically during startup of the machine. > This doesn't have anything to do with C1E. OK, that helps. Thanks. What else could be the cause of microcode_ctl not updating? Situation is: microcode: CPU0: patch_level=0x10000b7 microcode: CPU1: patch_level=0x10000b7 Is that new enough so that there is just no newer code to be uploaded for AMD Athlon(tm) II X2 235e Processor ?
