I've got two laptops one asus X501A and ome lenvo e520. I took the ram from the asus and put it into my lenovo they're different types so I wonder if it safe or it will cause any problems. I booted up the pc and it's recognizing both ram sticks and show the right amount of ram. so will this mix of ram cause any problems in the future?
