Ram in bios shows 4100 or (4000 more stable) mhz however cpu-z shows 2000mhz

mainboard asus
cpu i9
ram: CORSAIR Vengeance LPX 8GB (2 x 4GB) DDR4 DRAM DIMM 4133MHz Unbuffered 19-25-25-45 Black Heat spreader 1.4V XMP 2.0


Ram in bios shows 4100 or (4000 more stable) mhz however cpu-z shows 2000mhz where I did wrong ? is it normal for cpuz to show 2000mhz ?

How can I match 4133 in cpu-x ?

If I change to 19-25-25-45 computer doesn't boot stuck black screen therefore I had to change settings to 19-23-23-45

This is because CPU-Z shows non-DDR speeds. DDR stands for Double Data Rate hence 2000 MHz in CPU-Z = 4000 MHz actual speed. For example, my 3600 MHz kit appears as 1800 MHz in CPU-Z. Hope this helps!
