Is this RAM compatible with my PC (Aurora R6)?

Hello everyone. Just bought this Ram "Kingston Hyper X Fury HX426C15FBK2/16 16 GB 2 x 8 GB DDR4-RAM 2666 MHz CL 15-17-17" Link here PC-Arbeitsspeicher Kit Kingston Hyper X Fury HX426C15FBK2/16 16 GB 2 x 8 GB DDR4-RAM 2666 MHz CL 15-17-17 . After i removed my 16gb Ram in order to switch it with the new pair of 2x8gb, the alienware sign started to blink 4 times in orange/yellow. So i'm not sure if my system is not compatible with it or if the new pair of rams are having an issue. Already tried different slots (first time the two white ones, second time the two black ones and third time one black and one white) as well, outcome is still the same. Does anyone know which would be the case or maybe a different reason? I would be really happy, if one of you guys could help me. I just want to have a dual ram of at least 16gb in my PC.
