Hello guys, Curious if anyone knows if adding 2 more sticks of ram to this setup will prevent me from achieveing the whole 3600 mhz listed on the pkg. I have read online running 4 sticks means i wont hit max speed.

Asus Rog Strixx z390-H
i7-8700
2080TI
2x 8gig Gskill RGB 3600Mhz

I am looking to add 2 more sticks.
