sofar, my Raspi (Rev. A, latest stable Raspbian with all updates, latest raspi-config version) works very well, usually 24 hrs per day.
Since I want to use it as media center, I think that some overclocking is required to give it more muscles.
So, I used raspi-config to set overclocking to high.
This was acknowledged. When I checked config.txt, I saw that arm_freq was set to 950 Mhz.
Reboot. Checked config.txt again: 950 Mhz, but cat /proc/cpuinfo said that arm clock is at 697.95, which is a far cry from 950.
Can someone please help me ? Did I something wrong or did I miss anything ?
BTW a call of /opt/vc/bin/vcgencmd measure_clocks arm shows 7000000
So overclock parameter in config.txt did not have any effect
Thank you very much in advance for your help
