Does anyone know much about Turboboost on Nehalem? I would like to have some indication that this is working, and perhaps measure what effect it has. I have enabled Turboboost in the BIOS, however when I modprobe acpi_cpufreq I get
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.31.12-0.2-desktop/kernel/arch/x86/kernel/cpu/cpufreq/a cpi-cpufreq.ko): No such device Dave Jones' blog suggest this is a BIOS issue. Any ideas? I have tried BIOS flags for hardware and software control of CPU stepping. The contents of this email are confidential and for the exclusive use of the intended recipient.
