    I have an imac 27 2017 , and I would like to improve it adding 8 gb of ram. Do you think its better to buy 1 x8 gb or 2of 4 gb. I thought maybe for the future it is better to have an extra slot , but I have heard something about dual channel. The performance is the same ¿

    You want it in matched pairs. Dual channel is faster. But it will work with one. Search there forum there are other detailed threads on configurations, slots and placements. Personally I have stock 2x4GB plus 2x8GB. If I want more I will just keep spare or sell the 4GB’s.
