Just want to say that I get up to 2.7 on my Acer Aspire 5720Z laptop. cycles: out 3955, in 3679 cycles: out 3972, in 3683 cycles: out 3963, in 3692 cycles: out 3961, in 3663 cycles: out 3977, in 3679 cycles: out 3990, in 3675 The test program was run with the following frequency setup: # cpufreq-info cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to linux@brodo.de, please. analyzing CPU 0: driver: acpi-cpufreq CPUs which need to switch frequency at the same time: 0 1 hardware limits: 800 MHz - 1.47 GHz available frequency steps: 1.47 GHz, 1.07 GHz, 800 MHz available cpufreq governors: ondemand, userspace, performance current policy: frequency should be within 800 MHz and 1.47 GHz.
