i have a old gaming laptop, purchased it on 2019, i can still play modern games easily on moderate settings with 60+ fps, but i have 2x4= 8 gb dual channel ram and i think its holding me back a little, wanna upgrade it to 16 gigs, but 2x8 dual channel ram kits are kinda expensive, so if i just get 1x8 gb ram, and make it 16 gigs, do i lose the dual channel ? or 2x4 and 1x8 will work dual channel and single channel respectively? i know 2x8 would give me better performance but just wanted to ask...
