Several times ago i bought a Computer with a X370 Gaming k7 and a ryzen 7 1700X and 16gb DDR4 3200mhz G.SKILL. There was a problem with rams and i got a new rams. Now i noticed that there still are problems: sometimes the PC doesn't read all 16gb in windows, In single Channel mode it works fine, and still in dual channel mode without XMP profilw (but sometimes it crashes, rare). If I enable XMP the PC goes very bad ( BSOD, freezes ecc). Moreover, if I move the case, the PC crashes, i tried to reseat Ram and GPU, but the only result is that the rams work in Dual Channel but without XMP.
