Hi all, this issue been bothering me for quite sometime. Recently i purchased a Acer Nitro 5 AN515-43-R9B3 come with R5 3550H and RX560x GPU and 4GB 2666Mhz RAM. I installed additional 8GB 2400Mhz RAM to make it total 12GB of RAM but task manager shown 2.1GB as Hardware Reserved. Does Ryzen cpu reserved more ram memory for their integrated Vega 8 comparing to intel cpu? Would like to hear from others owner of Ryzen laptop user.
