Question Wrong RAM? Or how do I fix timings?

[ps2cho]

So I bought a 32GB pair of DDR4-4000 sticks. https://www.newegg.com/g-skill-32gb...-32GTZR-_-20-374-106-_-Product&quicklink=true

When I select 4000MHz in my Asus ROG X570 Crosshair XIII formula motherboard, I boot up and CPU-z is showing the following:
DRAM Freq: 2000MHz
FSB/RAM 3:60
CL: 28
tRCD: 27
tRP: 27
tRAS: 58
tRC: 92
CR: 1T

Why are my timings nowhere near the advertised > Timing 18-22-22-42
what should I tweak/do in my motherboard to get the best performance out of this kit, or did I simply buy the wrong kit and this isnt designed for AMD?

The QVL on Asus' website shows the 16GB kit as listed compatible (I have 32GB kit, but part# is the same otherwise (G.SKILL F4-4000C18D-16GTZR 2x 8GB SS Samsung 18-19-19-39 1.35v)

Did you go into the bios and set the memory profile to the XMP choice for 4000MHz? It's in the AI Tweaker section under AI Overclock Tuner, the XMP (DOCP) option.

Can you show screenshots from CPU-Z - memory and spd sections?
