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

isnt the DRAM frequency supposed to be 3000 ? what am i missing
 
Solution

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


Have you enabled the XMP memory profile in BIOS?
 


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