[SOLVED] Boot problem if more than one stick of RAM is installed ?

[mjvnts]

okey, first of all im sorry if this is a duplicate i havent found any solutions yet and wanted to ask myself mby there is someone who could help me out.

my problem is that my pc only starts with 1 ram stick in the A1 or A2 slot. If I install 2 or more the pc turns on but the dram light stays yellow and it wont completely boot up.
I tried every ram stick single channel so they‘re not broken as it seems.
I resetted my bios, updated my bios… I even tried adding more dram voltage and define the frequency manually because it said 2133mhz in bios which is standard i guess?

i really dont know what there is left to do ?

specs:
asus rog strix b450 f-gaming
ryzen 7 2700x
corsair vengeance pro rgb 4x8gb 2666mhz
nzxt kraken x52 cooler
geforce 1060 6gb (dont think is necessary)

thanks for everyones help i hope there is someone to fix my problem.

Hi mjvnts (y)and Welcome to the forum

Is your RAM kit listed on the MB QVL as a single kit that are tested?
If not sure then list the P/N.
They should work at 2666Mhz and if this continues then I would suspect the MB RAM slots.
There should be an XMP profile in Bios. Have you tried that?

This motherboard?

Ensure that you are installing supported RAM and that the RAM modules are a matched set for dual channel use.

Reference Pages ix, 1-5, and 1-6.

[Do verify that I found the correct motherboard user manual.]

Also go to the ASUS website to look for any updates regarding supported RAM. Reference QVL (Qualified Vendors List).
