Trouble setting up my new Ryzen on B450 Pro4

Hi guys, picking up from where I left off over the past 7 months or so. I am trying to desperately trying to upgrade the ram from 8GB to 16GB but to no success.

1. I tried to complement the original 2 Crucial rams by buying 2 similar sticks of Crucial rams. But these 2 new sticks have slightly different identification ending CT4G4DFS8213.A8FAR11. Once again the motherboard started boot-looping again and I have to take out the new 2 sticks which I installed.
2. Next I bought 4 sticks of ADATA DDR4 2133(15) 4GX8 U-DIMM with the all the same identification (AD4U2133W4G15-BHYA) thinking it might work. To my disappointment, the PC is displaying boot-looping again. I tried installing as 4 sticks before decreasing 2 sticks thinking that maybe the 2 ram slots are faulty. The results turn out negative so I have to revert back to my original 2 crucial rams.


I did a complete CMOS clearance (battery out, pressing against the jumper) for each time i attempt to install new rams. But it does not work.

Will someone please help me out here? I'm desperate.

Regarding the specs of the B450 Pro4, M2_1 does not support M.2 SATA3.
But your WD Green m.2 are M.2 SATA3 SSDs.
For this first M2 slot, you have to use a M.2 PCI Express SSD.

The to pins need a shortcut for some seconds (after switching off power supply and anplugging the cord from the wall as described in the manual). If no jumper on hand, use something else (tweezers) to make the shortcut. If this feels too dangerous for you, put two RAM sticks in A2/B2, switch on and try to get into the bios by pressing del key and load CMOS defaults. If this still does not work, remove the CMOS battery for some minutes or look for a jumper elsewhere. Maybe it is somewhere in the package of your mainboard.

Thank you Ray62 for the tweezers suggestion! That was all I needed because I was looking all around for the 'jumper cap' but there was none.

Now it boots up, I have another problem though.

My m.2_1 port is not working. I tried switching both my m.2 SSD into the port, but it cannot be read. Can anyone help me with that?

Current setup:
m.2_1 : Does not recognize any of my m.2
m.2_2 : Working with WD Green m.2 120GB / WD Green m.2 240GB
SATA3_A1 : Working with WD Green 2.5" 120GB
SATA3_A2 : Working with WD Green 2.5" 240GB
SATA3_1 : Empty
SATA3_2 : Empty
SATA3_3 : Empty
SATA3_4 : Empty

What is the problem?

Mixed RAM is definately a huge possibility!

Try just 2 sticks of RAM from the same type in solts A2/B2. Clear CMOS and check again. It should boot now.
