I changed the XMP from Auto to "XMP 2.0 Profile 1", then the DDR Frequency was set to DDR4-3603.

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.

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.
