Question Ryzen 3 3200g and ROG B450-F build issues - Power/ no post / no display

[MCAM77]

Hi all, I'm having issues with a new build and I'm hoping someone has some ideas. I have a ASUS ROG B450-F Gaming, Ryzen 3 3200G, 2 x 4GB DDR4 Viper 2400MHz and 2 x 4GB Corsair 2666MHz. Can't get the MB to post. Q-LEDs flash in sequence white, yellow, red and keeps cycling over and over with longer pauses on yellow and red. Tried using 1 stick at a time, same result. Swapped out CPU for a Ryzen 5 2600x and a cheap GPU, system boots no problem. Swapped the 3200g back in with the same GPU and no go, however this time Q-LED is solid yellow. Tried T-FORCE 3200MHz from the same working system that had the 2600x, still won't post. Installed the 3200g in the system I pulled the 2600x (B450M-PLUS, 8GB RX580, 2 x 8GB T-FORCE 3200MHz) and the B450 won't post either. I also updated the B450-F bios while the Ryzen 5 was installed.

Any other ideas? I'm at my wit's end with this processor.

Thanks!

You should always use matching sticks of RAM (either a 2 or 4 stick kit).

Try without a discrete GPU. Just Ryzen 3 3200G, 1 stick Corsair RAM (in second slot from the CPU), no drives. Goal is to get it to post and get into BIOS.

Thanks for the response. I've been trying everything. 8GB patriot kit PVE48G240C5KRD is listed on Asus QVL for board and processor, Corsair kit isn't listed. No drives are installed won't post with or without discrete graphics. Ram in A2 only Q-LED cycles white, yellow, red. Ram in A2 and B2 Q-LED solid yellow. Pretty sure it's not the board since it posts and registers all memory with the Ryzen 5 2600x. Maybe a faulty processor? I've also tried cleaning pins on the 3200g. Always same result.
