I'm planning to buy an 8gb DDR4 2666mhz stick from Ramsta and I have a 4gb 2666mhz stick of ram also made by Ramsta. I was wondering if I could use both 4gb and 8gb together without any problems??

My current specs:
Cpu: I3 9100f
Gpu: Rx 560 2gb
Motherboard: Asus Prime H310M-E R2.0
Ram: Ramsta 4gb DDR4 2666mhz
Storage:
WD 500gb HDD
Kingston 128 SSD
PSU: 250w
