Hi,

I tried the testing XBMC RC3 & new firmware and everything seems to work until I tried some high bitrate + DTS movie. I just saw that overclocking is not working anymore.

I don't know if it's a problem with new firmware, I didn't try before upgrading firmware

My config.txt is :

Code:

arm_freq=900                                                                                                                                                                                  

core_freq=375                                                                                                                                                                                 

disable_overscan=1                                                                                                                                                                            

gpu_mem_256=128                                                                                                                                                                               

gpu_mem_512=128                                                                                                                                                                               

sdram_freq=450                                                                                                                                                                                

over_voltage=0                                                                                                                                                                                

hdmi_ignore_cec_init=1                                                                                                                                                                        

initial_turbo=30

cpufreq detects my overclocking :

Code:

xbian@xbian:~# dmesg |grep cpufreq                                                                                                                                                            

[    1.190855] bcm2835-cpufreq: min=700000 max=900000 cur=900000

but the arm freq while watching movies is stuck @ 700 Mhz :

Code:

xbian@xbian:~# sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq                                                                                                                 

700000

If i switch to ondemand governor, the arm goes @ 900 Mhz on load and the movie plays fluently.

Does anybody have the same problem ?

Thx.

Did you check:

Code:

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

While running in performance mode?

Yes, it was 700 Mhz with performance governor

The there is cleary something wrong with your install. Did you run rpi-update?

Also, can you post a full dmesg on pastebin and post the link here?

Here is my full dmesg : http://pastebin.com/rMJgyAWw

Tonight I will try to revert to standard xbian config.txt just in case.

kernel seems fine...

Ok, solved, the guilty is the initial_turbo=30. Thx anyway for help.

You're welcome!

Hello,

it seems i have a similar problem.

My Pi is overlocked to 1 GHZ.

dmesg shows this

Code:

root@xbian:/home/xbian# dmesg |grep cpufreq

[    1.248761] bcm2835-cpufreq: min=700000 max=1000000 cur=700000

[    1.249058] bcm2835-cpufreq: switching to governor performancebcm2835-cpufreq: switching to governor performance

then cat cur freq

Code:

root@xbian:/home/xbian# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

1000000

and cat cpuinfo shows this

Code:

root@xbian:/home/xbian# cat /proc/cpuinfo

I have 3 different values, which one is the right? Smile

Every command was executed while running an 1080p movie.

The second

The other two only show the specs as stated by the manufacturer

ok, then everything should be fine.

Thank you.
