Rasplex Overclock

Hi

 

Is it possible to overclock a raspberry pi running rasplex and if so can someone point me to a guide?

 

Thanks

If i remember right, sftp or ssh into your rasplex (while turned on) and in there you will see a config file. within this you will see the settings for your overclocking.

I believe that is inaccurate.  Your best bet would be to remove the SD card and edit the config file on another computer.  Rasplex is already overclocked, however.

The config with overclock settings is in /flash/config.txt. Default the /flash/ folder is mounted as read only, so:

1) first login on your rasplex using ssh as root;

2) execute mount -o remount,rw /flash

3) edit /flash/config.txt using nano: nano /flash/config.txt

4) reboot using reboot

Thanks guys, but if its already overclocked I guess i can't get much more performance out of it by overclocking anymore?

you can get a lot more out of it

@dansvarre:
how exactly?
Thanks!

it`s possible to overclock a lot more than standard rasplex and it makes a big difference in my system.

could you post your overclock settings? Thanks

This is my config.txt file:

# Overclock Settings
arm_freq=1000
core_freq=500
sdram_freq=500
over_voltage=4

# GPU Settings
gpu_mem=128
cma_lwm=16
cma_hwm=32
cma_offline_start=16

This is my config.txt file:

# Overclock Settings
arm_freq=1000
core_freq=500
sdram_freq=500
over_voltage=4

# GPU Settings
gpu_mem=128
cma_lwm=16
cma_hwm=32
cma_offline_start=16

is that off your sd card or usb?

And do you use any active cooling to get these numbers?

We played around with over-clocking a bit but it seemed to make not that much difference and causes a lot of trouble with some RPis.

Have you experienced a measurable performance improvement?

(More than a good feeling after finally getting the overclocking settings working)

Thanks.

In my system it makes a great difference in load times on home screen and navigating sections. Aktually it also makes the pi able to play remuxed bluray rips.

arm_freq=950
core_freq=450
sdram_freq=450
over_voltage=1

Anything above this only makes it unstable. This is my sweetspot :-)

Hi, sorry only replying now, totally forgot about this thread. That is running off a class 10 SD card. No active cooling. Its in a standard plastic case, no heatsinks etc. Doesnt seem to get noticeably warm at all.

As for performance improvements, i do notice that menu navigation is a "bit" quicker, but again, maybe thats just my imagination, but i do feel it makes a slight difference. Main reason for overclocking was that i dual boot the system with Raspbian using BerryBoot off one SD card using the same config.txt and the overclock makes a more noticeable difference in Raspbian than it does in RasPlex
