I have a acer aspire vx15 entry level gaming laptop. It came with 8Gbs of DDR4 -2400 Mhz Micron ram. Now, will it be an issue if I add a second stick of DDR 4 - 2400mhz ram, but the brand is Crucial memory. I know Crucial uses micron ram chips and is part of Micron, so I'm hoping it won't be an issue, they both 1.2V chips with the same specs. Will mixing these brands be a problem ?
