Yeah, it uses DDR4 RAM.
I wish you asked for advice first before making your purchase. I would have recommended the following Acer Aspire E 15 E5-575-33BM for the same price, but it has better specs. The Core i3-7100u is a much more powerful processor than the A6-9200 series APU, even though the i3-7100u is considered weak when compared to Core i5 and Core i7 CPUs (especially the quad core versions). The Intel HD 620 is also considerably more powerful than the Radeon R4 (Stoney Ridge) integrated graphics cores even though the Intel HD 620 (in 7th gen Intel Core CPUs) is considered weak itself. The Radeon R4 is about equivalent to the Intel HD 4000 (in 3rd gen Intel Core CPUs) that was released back in late 2011. The Acer also has a 1920x1080 resolution rather than a 1366x768 resolution screen.
