Hi !
I saw many tutos talking about overcloking RPI 2 (here) for use of media center for example. In case of Rasplex v0.6.0, do you recommend to overclock RPI 2 ? Espcially gpu_mem or arm_freq ? Or which field need to be changed ?
Thank you !

To my knowledge the RPi foundation still has not issued ANY information on valid overclock modes for the RPi2.
So everything you do is based on guesswork (your own or some internet poster's), and is done at your own risk.
I have made a few attempts myself, based on on info similar to what you mention and claimed to be valid for the RPi2.
But I quickly abandoned those attempts after 'weird' errors which have no other explanation than that overclocking.
For the time being, until OFFICIAL recommendations are available, I advise everyone to avoid overclocking the RPi2.
Btw: gpu_mem is not a clock setting, but specifies the amount of RAM reserved for GPU usage. (in MegaBytes)

Ok ! Thanks a lot for your advises !

Whilst I agree with what @dlanor is saying you could try the following:
arm_freq=1000
sdram_freq=500
core_freq=500
over_voltage=2
I have been running one of my Rpi2 24/7 with these settings for the past 8 weeks with no issues.
If your RPi2 is in a hot environment you may wish to add the following:
arm_freq_min=400
sdram_freq_min=250
core_freq_min=250
initial_turbo=30 #Does not affect warranty. (Speeds up boot)
The arm_freq setting will add some heat to the board when pushed, however, you can improve performance without overclocking the arm_req as follows:
sdam_freq=500
core_freq=500
over_voltage=2
I have another RPi2 with extreme speed settings (this has only been running for a few days but seems stable) as follows:
arm_freq=1100
sdram_freq=500
core_freq=500
over_voltage=6
temp_limit=80 #Will throttle to default clock speed if temp is hit.
Note: Applying any of these settings are at your own risk, I will not accept responsibility for any damage you may incur!
As you would expect at 1000MHz overclock it only gives you an extra 100MHz over four cores (1000Mhz for each core), with the previous Model B if you added 400Mz to the one core it would give you 1100Mz, however 1000Mhz over four cores is better than 1100Mz on one core.

hi
first.. I overclocked my Rpi 1 when running xbmc because I felt it was lagging..
after switching to plex.. I really haven't had any reason to overclock.. and especially now when I run RpI2..
What's your reason for wanting to overclock? just because you can or do you see any issues you believe overclocking will solve?
I have tried overclocking my Pi 2 following Ned’s suggestions, although it was stable I could not discern any difference to its non overclocked performance, perhaps at the moment there is no need for overclocking.
Considering the Pi B that I have runs 0.6.0 out of the box awesomely... (I realize the default config for Pi1 is set to High overclocking, non-forced turbo) I don't really see the point, the Pi2 steamrollers Rasplex, better to protect the longevity of the device and leave it stock.
