What brand and kit do you recommend and I just want to use two slots to get 16gbHow many threads do you need to initiate? You also need to be patient for a response/post/suggestion/answer. If you read the technical guide book I'd linked, you'll learn the maximum ram capacity is indeed 16GB but you've got 4 slots, divided the max capacity with the number of slots. You get a 4x4GB kit requirement for your Dell OptiPlex 7010 MT system.
Short answer; that kit you've linked won't work. 4x4GB DDR3-1600MHz 1.65v kit.
