[skeleton.anas]

hello, i just finished building my pc and i have this problem

my motherboard is MSI Z370-A PRO, first time i ran the pc i got like this screen for few seconds

i did userbenchmark test and everything was fine expect ram it was "performing below expectations"

then i changed ram slots ( there is 4 slots ) and i didn't get the error message, but i did the test again and still performing below expectations.

this is from cpu-z

Have you enabled the XMP memory profile in BIOS?

i just did and the DRAM frequency became 1500 mhz only
is this normal ?

Since it is DDR4 (Dual Data Rate), you double the 1500 MHz for 3000MHz, so,Yes it is normal.
