Question Some RAM issues!

[zerothelightbringer]

So I have a number of "issues" with my RAM. The ram works fine but it is currently clocked at only 2133 mhz. I have 4 sticks in total one pair is AX4U300038G16A-DATA & the other pair is F4-3000C15D-16GTZR. My motherboard is a B350 ROG STRIX Gaming & my CPU is a Ryzen 3600. They don't run at the same speeds. In my BIOS I see the ADATA at 1333 aka 2666 but the Gskill are at 1066 when I check while in windows it shows my ram speed as 1333. I have updated my BIOS to the most recent version as well. I have tried to turn on XMP & that just makes my PC stop posting or I get bluescreens when I restart my PC. Everything is stable at 2133 but I would like to figure out why I can't seem to go above it. I know the RAM timings can mean a lot but I honestly have no clue where to start with finding the right timings since they are two different brands. Do I have to get matching sticks? So all 4 A-DATA or all 4 being the Gskill?

Any help would be appreciated! Thank you in advance!
