A:AnswerYou cannot get the memory pre-installed before purchase; but you can definitely reach out to Best Buy's Geek Squad team to see if they can assist in upgrading the RAM!
A:AnswerAbsolutely. Bought it for my wife a couple of weeks ago.
Been in IT for 30 years. I have really been pushing it hard.
It has come through with flying colors. Excellent buy especially for the price.
Peace,
