Overclocking Pi 2
#1
What config file settings should be possible?

Are we going pretty much the same, except "arm_freq" and "gpu_mem"?

Gazes into Raspberry shaped crystal ball and mutters incantations to try and summon that bloke who likes mixed Popcorn...... Oo

Raspberry coloured smoke appears, and out of it steps....

Got my Pi2 this morning, works quite well with these settings.
Will see how far I can go up with the arm_freq Huh

arm_freq=1100
core_freq=520
sdram_freq=520
gpu_freq=510
isp_freq=510
gpu_mem_1024=256
over_voltage_sdram=6
over_voltage=8
current_limit_override=1
force_turbo=1
hdmi_force_hotplug=1
hdmi_drive=2

Don't make it smoke! Smile

And what's your experience in general with the new Pi2? Snappier? Much faster? etc? I have the original Pi and am very interested in this and if things navigate much quicker, etc!

My Pi monitoring tool, bcmstat, has been updated with multi-core support. Can be useful to monitor your clock speeds, network throughput, CPU and memory performance.
Texture Cache Maintenance Utility: Preload your texture cache for optimal UI performance. Remotely manage media libraries. Purge unused artwork to free up space. Find missing media. Configurable QA check to highlight metadata issues. Aid in diagnosis of library and cache related problems.

Oh, didn't know bcmstat, just tried it on my Pi 1 B and it's really useful. Thanks @Milhouse!

I've gone for a lower overclock then Chrisiooo
I'm running at:
arm_freq=950
force_turbo=1
gpu_mem=256

Be nice to see if I can get up to 1000MHz with no overvoltage, to be honest I'm quite happy with the default settings. I prefer this to my hummingboard i2ex which I paid double the price Smile

Is the Leopold .Unofficial Raspberry Pi configuration addon working on the Pi2?

Yes. Used it to update to Milhouse's latest Pi2 build last night.

Cool so the overclock option is working?! Smile

Ah sorry - I tested his OE updater addon. Not tested the config editor.

I would guess it will work, but doesn't include a Pi2 specific overclock setting.

Just set it to arm_freq=1000, core_freq=500, sdram_freq=500, over_voltage=2 manually for now.

Tested different config file setup´s and ended up with this:

OS is the latest Openelec build #0203 from Milhouse
arm_freq=1100
core_freq=520
sdram_freq=520
over_voltage=8
over_voltage_sdram=6
gpu_mem=256
force_turbo=1
disable_overscan=1
avoid_pwm_pll=1
current_limit_override=1
hdmi_force_hotplug=1
hdmi_drive=2


arm_freq=1100 was the highest value I can get without freezing the Pi during Usage.

But the backpower method with a USB Y-Cable isn´t working, like I did with my old Pi B. I think the reason why I can´t go over 1100freq is the less power provide through the micro usb port. Any Idea how I can get this working again?

With this setting everything runs really smooth, from my feeling much smoother than with standard settings.
I use the skin 1080XF with many Addons and boblightd active, also playing 1080p movies in the background while scrolling through my movie list ist possible without any lack of speed.
