A:Answer This Lenovo IdeaPad 3 15 Gaming Laptop, model number 82K201XCUS, ships with 8GB DDR4-3200MHz RAM installed (1x 8GB SO-DIMM DDR4-3200MHz RAM). There are two DDR4 SO-DIMM slots, dual-channel capable. As long as the RAM you are using is DDR4, you will see a reduction in performance, but the RAM should be compatible. We recommend you consult your certified technician about your RAM upgrade options.
