this would be my first time buying a gaming laptop, i used to play on the ps and i got a couple of questions

first of all i've heard about the rams etc, i just wanted to be sure of the rams used in the 15IRX10, is it ddr5 or ddr4?

i know that the same kind might have different specs, so i provided these photos

Thanks in advance
