ROC-RK3328-CC Showing lower clocks

Hello all, I have had my Firefly board for some time now and finally found time to come back to it and run Ubuntu instead of just a media server. However I noticed that I am not getting full clock speeds.

I’m running the official Ubuntu_base image but only showing the output below.

cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies
408000 600000 816000 1008000 1200000 1296000

Any ideas? I thought this board was clocked at 1.4Ghz.

Any help is useful.

Thank you
