I'm trying to replace my single channel 8G RAM with dual channel 16GB RAM. I keep getting black screen on start up with new RAM. Old RAM works but is damage. My old RAM was DDR3L and I mistakenly ordered regular DDR3 RAM, is this my problem? Does that matter? Also I have a Acer Aspire E15 E5 573G laptop if that helps answer. Thanks in advance this is very frustrating.
