The default gpu_mem (when NOT set in config.txt) is 64MB. The default in OpenELEC for the Pi2 is 256MB.
I've found that when running the GUI at 1080 with high colour depth and higher quality fanart/imageres settings in advancedsettings.xml, gpu_mem=320 is necessary to eliminate resource issues.

Is this normal with Openelec?
Shouldn´t it be "disable_l2cache=0"?

It seems to be normal for all operating systems - same with Raspbian.
Enabling l2cache (disable_l2cache=0) will hang kodi.bin on startup. vcgencmd will also hang.

Ok, i just wondered because of the official explanation from the config.txt
Also added your gpu_mem value, thanks for this tip.

what is over_voltage_avs=0x1b774, program_serial_random=1, config_hdmi_boost=2, arm_control=0xa5800010 and ignore_lcd=1?

Reading this thread, it appears that "arm_freq=1000, core_freq=500, sdram_freq=500, over_voltage=2" has the standard mentioned by the experts. Two questions:
1) Can I still use Leo's old config tool to make this setting or better to do manually?
2) It appears that my RPi2 cannot handle the over-voltage=2 as my powersupply cannot supply enough voltage to make it work (I am using the USB from the Bravia). This is unfortunate as it used to work with the RPi and also worked with RPi2 without OC. What's the best I can try without over_voltage or with overvoltage=1?
Thanks!!!

Well, the best you can try is actually to do yourself a favour and get a decent 5.0V 2A power supply for you PI 2. It isn't meant to be powered by the USB out of your Bravia. If overvoltage 2 is already a problem my guess would be that even without overclocking you are already running on the limit.

One of the main reasons for using a RPi is that I don't need an extra powersupply (I really dislike cables), so I would love to find a way to get things working powered by the Bravia. It worked perfectly with the RPi1 and I do not have any USB devices attached.
Are you suggesting that I can save some power by turning off max_usb_current?
Let me try Leopold's new update of the config tool. Can it be installed from his old repo?
