Overclock Raspberry Pi2 with yunohost

the raspberry pi 2 come configured to 700mhz,so i am trying to overclock a little,but i always have corrupted mysql databases after some days…even at 800/900mhz/1000MHz overclock… i change the usb power supply for one better,but its not a 2amps,im waiting for a new one to come.

and i found this in internet and it works:

check

tail -500 /var/log/kern.log

if you have this lines sometimes:

raspberrypi kernel: [63730.611441] smsc95xx 1-1.1:1.0 eth1: kevent 2 may have been dropped
raspberrypi kernel: [63730.627113] smsc95xx 1-1.1:1.0 eth1: kevent 2 may have been dropped
raspberrypi kernel: [63730.643020] smsc95xx 1-1.1:1.0 eth1: kevent 2 may have been dropped
raspberrypi kernel: [63730.658552] smsc95xx 1-1.1:1.0 eth1: kevent 2 may have been dropped

edit /etc/sysctl.conf
and #Uncomment some lines from net.ipv4 and .ipv6 for better security…

and add this lines in the end

vm.swappiness=25
vm.min_free_kbytes = 8192
vm.vfs_cache_pressure = 50
vm.overcommit_memory = 1

this resolve the problem with this errors in kernel

im still trying to find a stable overclock with yunohost
you can try edit the /boot/config.txt
or use raspi-config

and you can tell in this thread what is working for you in the raspberry pi 2

now im waiting for a better power supply to continue my tests… :smiley:
