Hi Tom,
that one came with 32 GB RAM. I don’t know how to upgrade a Laptop’s RAM, but on a Desktop, it is best to have the exact same make and model and if possible use 2 RAM ‘sticks’ for best performance (if you have 2 x 8 and want to upgrade to 32 GB, it is best to go for 2 x 16 and not 4 x 8 or 1 x 32…)
