so I got this old netbook from a friend and she wants me to make it usable. I installed Xubuntu but it seems that this ESH settings in BIOS which should overclock CPU up to 30% does not work! When I do cat /proc/cpuinfo|grep MHz I still see numbers around 1300 and not 1.74GHz as I hoped even when CPU load is high. I installed this TLP package (http://www.webupd8.org/2013/04/improve-power-usage-battery-life-in.html) thinking that this is necessary to make ESH work, but still it's the same. If I run sudo tlp-stat -p I get

Isn't this boost (not available) the problem? Any ideas how to make this CPU work faster? Youtube is unwatchable even at frikin 360p unfortunately like this :-\
What if I just put some number to scaling_max_freq into TLP config /etc/default/tlp? Can I just put there any number of MHz, would it take it?
