did they come as part of a kit? If they are not from the same kit then your mileage may vary. Are you looking to buy these or do you already have them? on top of taking the chance that they don’t work together, dual channel is normally something that is handled more by the motherboard rather than the RAM themselves. You will need to consult the manual for your motherboard to see if it supports dual channel. Furthermore, if you are buying these online brand new, you are spending far more money for these RAM than you would on other RAM that actually come in a kit. Like the the G.Skill AEGIS 16GB (2×8) 1600Mhz kit for $75 on Newegg https://www.newegg.com/Product/Product.aspx?Item=N82E16820231746 Or if you live in a country that isn’t America then these RAM might not be the best deal. Let me know what’s up with the answers to all my above questions.
