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
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
