ok i got pi.how do overclock it in openelec and how can test my internet connection.I am using wifi at the moment seems slow in places loading content. any ideas to make run better.

mount /flash -o remount,rw
nano /flash/config.txt

The file system is normally read only, so to edit the required file you need to remount it as read/write with
Code:mount /flash -o remount,rw
To edit the config.txt file you use
Code:nano /flash/config.txt
There are some settings in the file itself that you can use as a starting point.

You'd be using a Micro SD card to boot? You did set that up with your Windows PC? Or a different PC?
Can you read the content of the SD card with your PC? Is there a file called config.txt?
Look for the following lines:
Code:# arm_freq=700
# core_freq=250
# sdram_freq=400
# over_voltage=0
These are your overclock settings. Uncomment and set as desired. Good suggestions should be in comments right above these entries.

Yes i've got noobs card ,I will try it out later, what is safe overclock setting for Pi+ without killing it.
# Overclock mode settings.
#
# default recommended values are: arm_freq | core_freq | sdram_freq | over_voltage
# no overclocking : 700 | 250 | 400 | 0
# mode 'Modest' : 800 | 300 | 400 | 0
# mode 'Medium' : 900 | 333 | 450 | 2
# mode 'High' : 950 | 450 | 450 | 6
# mode 'Turbo' : 1000 | 500 | 500 | 6
arm_freq=1000
core_freq=500
sdram_freq=500
over_voltage=6
# set to 'force_turbo=1' to disable dynamic overclocking (you can lose your warranty!)
force_turbo=0

force_turbo=0
As you can see it has a table of values above it that you can use as a guide. the force_turbo= 0 means it overclocks dynamically. Changing 0 to 1 keeps it always overclocked. Its fine left at zero. Below is an example file that I used.
config.txt

(2014-08-08, 13:33)calev Wrote: The setting above is safe. If you notice it restarting or freezing, you may have to lower the overclock. Sometimes a bad power supply can cause those problems as well. SD card issue is fixed, shouldn't be a problem but there is always a chance for corruption when restarting without properly shutting down. It runs much better with this overclock especially when streaming stuff. Don't really have a good recommendation for a speed test. You could transfer a file over samba to get a good idea.
Edit: meant the setting above media pi's. His setting is a little more intense and fewer pis are going to work with that setting. His will also lose your warranty.
