I changed the XMP from Auto to "XMP 2.0 Profile 1", then the DDR Frequency was set to DDR4-3603.
This had dramatic effect on my CPU. The CPU frequency dropped from 3600MHz to 2600MHz.
I tried to set various memory speed in UEFI and the higher speed I choose the lower frequency I got on the CPU.

After I changed XMP the memory frequency increased from 2133MHz to 2745MHz
However running dmidecode in Linux it could only see 2 of 4 memory modules.
Handle 0x0018, DMI type 17, 40 bytes
Memory Device
        Array Handle: 0x000F
        Error Information Handle: Not Provided
        Total Width: 72 bits
        Data Width: 72 bits
        Size: 8192 MB
        Form Factor: DIMM
        Set: None
        Locator: DIMM_D1
        Bank Locator: NODE 1
        Type: DDR4
        Type Detail: Synchronous
        Speed: 2745 MHz
        Manufacturer: Undefined
        Serial Number: 00000000
        Asset Tag: DIMM_D1_AssetTag
        Part Number: F4-3600C17-8GTZ    
        Rank: 1
        Configured Clock Speed: 2745 MHz
        Minimum Voltage: Unknown
        Maximum Voltage: Unknown
        Configured Voltage: Unknown

I changed the XMP back to Auto and everything was fine, but I want my memory to run at higher speed and preferably at 3000MHz without speed impact on the CPU.
