You might be able to disable these features:
-
In your system's BIOS setup windows, look for settings labeled PowerNow or Cool'N'Quiet, and disable them.
-
If you are running a Linux host operating system, look for a system daemon or applet called cpufreqd, cpuspeed, powernowd, cpudyn, speedy, or cpufreq, and disable it. For example, on some systems the command service cpuspeed stop might work. The instructions to disable the daemon or applet found on your system vary. Refer to your system's documentation for more information.
