Otherwise, I have the code ready for you again: All you have to do is look for the line setenv ddr_freq 825 in /media/boot/boot.ini and replace the 825 with 933. By default it runs at 825 MHz and it is extremely easy to overclock it to 933 MHz. Hardkernel made it very easy to overclock the ODROID-XU4 RAM.

Quite simply: the faster the clock rate, the higher the bandwidth. The clock rate of RAM determines how high the data rate is set. On startup, it’ll pick the new kernel and will use the newly defined clock rates. When it’s done compiling, you can restart the ODROID-XU4 with the “reboot” command in your terminal.
#Odroid xu4 recalbox 4.1 install

#Odroid xu4 recalbox 4.1 manual
But now enough for the benchmarks! How can the CPU be overclocked? Thanks to ridge's observations in the code of the kernel, he wrote a little tutorial, available here: įrom the manual I copied the needed code just log in as root and copy the following script into your terminal. Of course the CPU Governor was set to performance. $ sysbench -test=cpu -num-threads=8 runĪll commands were executed three times and the average was taken from the results. $ taskset -c 4,5,6,7 sysbench -test=cpu -num-threads=4 run $ taskset -c 0,1,2,3 sysbench -test=cpu -num-threads=4 run Especially the little cores because their base clock is only 1.5 GHz. Here are the first of the results (lower is better): Core-TypeĪs you can see, with an increase of only 0.1 GHz you get much better performance.

To illustrate the performance increase I did a small benchmark with sysbench. I couldn't find any problems or crashes during my 1 week test phase and would describe it as stable.

I'll explain below how to customize and compile the kernel to use 1.6 GHz and 2.1 GHz as maximum clock speeds. Unfortunately, stability problems are inevitably left out until you have put together a perfectly functioning setup.īy default the four little cores, these are the processor's economical ARM cores, and the four BIG cores, performance focused cores, are operated with a maximum clock speed of 1.5 GHz and 2.0 GHz respectively. The general problem is thermal throttling, automatically underclocking the processor to decrease the chance of damaging the hardware. To prevent the latter problem, I recommend swapping the stock fan, as described in my article here. Hardkernel advises against changing the CPU clock speed values of the ODROID-XU4, since it can cause stability and heat issues.

Note: Any changes to your system can potentially void your warranty and negatively impact the system’s stability, so every change is made on your own responsibility. The original German article can be found here: This article is an authorized translation of the german article “ODROID-XU4: Tweaks unter Ubuntu 18.04 und Kernel 4.14”. In this article I would like to share what I have learned. During the time I’ve used it, I found out several tweaks that improved the speed or decreased the power consumption. Like many others, I’m interested in getting the most out of my ODROID-XU4.
