[SOLVED] Dual Channel Ram or more Ram?

[Metamorposis]

I have a Ideapad 330-15arr and it has a ryzen 3 2200u with an integrated graphics, 4gb ram that is soldered. The question is which will be the best approach since i read that dual channel ram will increase the dedicated vram of the integrated gpu. More ram that is single channel or dual channel?

Memory

Maximum Memory: 20GB

Slots: 1 (1 bank of 1)

Standard Memory: 4GB non-removable

Supported memory for Ryzen 3 2200U: DDR4-2400

It uses one regular DDR4 SO-DIMM up to 16GB in size. 2400MHz looks to be a good speed for it.

Can i change my Vram with more ram?
