A friend of mine got himself literally the same setup (He had B2 and bought B3) doesn't work for some reason, I'd say it's safer to buy the same revision, but from a different package because it's easier to find, K2/16 for example, K2 means Kit of 2 sticks and /16 means that total of 16GB ram is in the package, so the sticks are literally the same, just from a different kit, told my friend to do that, I'll update if there will be any issues but it should have zero chance of not working
