It doesn't explain why GPUs that are integrated into a CPU (like AMD's ones) and use the same memory, cannot use it all.
If they could use all memory, you could cheaply run neural networks with 64Gb of RAM without buying a professional GPU. No wonder manufacturers don't want you to be able to do that.
