My specs
r5 1600 W. stock cooler
ROG strix b350-f-gaming
corsair lpx 2*4 gb 3000 mhz 15 CL
Gtx 1060 3 gb
Evga gq 650 80+ gold
intel 540s 240 gb ssd

My problem:
ok this is a newly built system, that when I only use one stick of ram only one of them work, but when used together. In system informationjit says 8 gb of ram but every time I boot up a game it crashes. And I have Bsod often like: Video_Internal_Scheduler_Error. But when I use on stick of ram (4gb).My pc only boot with one of them. And when it boots with the one that works it works fine. only some freezez after long time of gaming/up time.
