RAM no longer hardware reserved after getting new CPU/GPU?

[Xorph]

I have 16GB of ram installed in my computer, as two 4gb sticks and one 8gb stick. Today, I upgraded my old Phenom II CPU to an FX-8350, and my GPU from a Radeon 7770 to an R9 380x. Until today, 4gb of my ram was always listed as Hardware Reserved, but now only around 32MB is reserved, and I'm wondering exactly why upgrading my CPU and GPU changed this. Thanks in advance for any help!

It was using your DRAM as shared memory to your old GPU, your 380X has plenty of dedicated DRAM on the card itself, the 7770s only had 1GB od DRAM, also the 8350 manages DRAM better
