VU DUO 4K SE RAM AMOUNT

When I check the RAM of my vu duo 4k SE device, it appears to be 1.5 GB, whereas it says 3 GB RAM on the box. Does anyone have information about this issue?

How do you check it?

with press " long yellow "?

Yeah, that's normal, because the kernel is configured to only give 1.5G to user space; look at /var/log/messages, where you can see how to memory is partitioned.

On my Solo4k with 2G it looks like:

Your "missing" memory is likely reserved for use of the DVB drivers. FBC obviously needs some memory, which this layout probably guaranties.
