Regarding to the RAM that u selected, if the RAM isn't in the QVL that doesn't mean that the RAM don't works with the mobo that only means that the mobo's manufacturer don't tested the mobo with that model.
Thank you for quick answer,
I'm glad that you're telling me about G.Skill Pi but in my country for them I have to paid 33$ more then for those G.Skill Ripjaws and another 66$ for G.Skill Trident F3-16000CL9T-6GBTD.
I've read about them and there is no big reason to go in 2000mHz memory. According to tests I should find something with 1600mHz because I wont fell such big difference (it's not my own opinion).
I'm looking only for some G.Skill memory so is there worth to pay this 33$ extra money for those Pi?
In this computer there wont be more memory then 3x2Gb.
It's not about buying something cheap but buying well so that's why I've come to this forum, first time in my live
