Hi Krzysztof,
Thanks to look at it.
mem_gov is /sys/class/devfreq/10c2.memory-controller/governor
Here some numbers after increasing the running time:

Hi everybody,
Is DVFS for memory bus really working on Odroid XU3/4 board?

seems to not working properly:
The microbenchmark is doing pointer chasing by following index in an array.
Indices in the array are set to
25 matches
