Advanced Plus just 2GB RAM in Windows

Hi fellow Udoo users!

Bios shows 4GB of RAM, Channel A 2GB, Channel B 2GB.
CPU-Z shows 2GB in "Memory" - in "SPD" I am able to select the two slots but everyhing is greyed out.

I am running VVVV with a particle simulation on it.
Task Manager Shows exactly 1GB of 2GB used.
GPU VRAM says 1GB used.

So the GPU has reserved that 1GB and Windows is strugging with the remaining 1GB.
Do I have a defective board?

regards, A

 

What Windows version did you install? You need an x64 version.
