Ryzen can't run on designed RAM speed of 2933 MHz.

[kubikolos]

Hello guys! I have some weird problem. I can't set my RAM on the highest settings possibile which is 2933 MHz. I have all 4 modules installed with same exact RAM modules which is golden ADATA AX4U3000W4G16-DGZ x2. I mean it's its 4x4 GB. I\ve tried setting all vaules manually and by Auto and still couldn't run it higher than 2400 MHz. When I had only 2 RAM modules installed I could even set them to 2800 MHz. My mobo is MSI B350 PC MATE paired with Ryzen 5 1500X.

EDIT:
I have the newest BIOS installed as of right now.

Purchase memory on the QVL to ensure compatibility. Especially for 300 series motherboards.

return the 2 kit and get a 4x4GB kit

by that table this tam is working only in 2400 speeds. and this is exactly the result you're complaining about ?

When all 4 channels are populated the max speed they will run is 2666 on 400 series and 2400 on 300. This is on amd's page for the 300 series of motherboards. It is only within dual channel 2/4 channels populated that you would see the 2933 memory speed.

ADATA AX4U3000W4G16-DGZ is a kit of two modules.

Using multiple kits is something not guaranteed to work by memory manufacturers. You may have to run at a slower memory clock speed to get such a combination to work.

Populating all slots in a B350 PC MATE will also cause the memory to run slower than with just two modules.
