[SOLVED] Can't get remotely close to advertised speed

[my name is jeff]

Can't run my ram at a frequency beyond 3600 Mhz even though it is supposed to run at 4400 Mhz. I tried using the D.O.C.P profile, changing the frequency while leaving CAS and voltage the same as the D.O.C.P profile. 3600 Mhz seems to be the highest I can run. I am running the two sticks in slots a2 and b2

CPU: Ryzen 2700x
Memory: 2x16Gb g-skill 4400Mhz
Mobo: Asus z170

I also tested it with one stick and it fails to boot 3 times and goes into safe mode, like with two sticks

If your mobo is the z170-a I think you will find the max ram speed is 3600.
