What do you derive from that the maximum freq isn't 800MHz _after_ you set it? All the CPUs are in P15 as per the output you supplied, which is a good indication that no lower P-state is in use anymore (as even the CPU where the command was carried out was still in P15). Lower P-states would of course have been in use prior to you running xenpm. Sadly while there is a way to reset the statistics, the hypercall subfunction isn't wired up beyond the libxc wrapper function. > Why are my fans running at full speed and why doesn't xenpm maximum frequency > setting work? I'm afraid I can't answer this question, as I don't know how exactly fan speed is controlled on that system of yours. Jan
