Ryzen 7 3800X and RAM problems

Hi Everyone,

So I built a PC the other day using:

MSI B450 Mortar Titanium MB

Ryzen 7 3800X

Corsair H60

Corsair Vengeance LPX 2X8GB DDR4 2400MHz CL16 CMK16GX4M2A2400C16 (2 sets, total of 32Gb by 4 sticks of 8gb (2 sets of 16gb))

Kingstone A1000 nvme 480gb SSD

Asus RTX 2080TI Dual Advanced GPU

Samsung EVO 850 480gb

Coolermaster 750W platinum 80+ PSU 


then I updated the bios to the last version (16/6/2020 ver) and then went into the bios and switched to XMP mode, 

BUT I went into a problem...., when I tested the PC using Userbenchmark my memory went like 60 to 72 percentile which is a very low score, then I opened the CPU-Z software and saw the following information:

Slot#1: 8gb 2400Mhz

Slot#2: 8gb 2133Mhz

Slot#3: 8gb 2400Mhz

Slot#4: 8gb 2133Mhz


PLEASE(!) if someone can tell me why does the CPU-Z is showing some of the memory sticks as 2133Mhz and not 2400Mhz???? 

Can someone help me to solve this issue?, thanks in advance!!
