Question DRAM then CPU Q-LED, no POST ?

[9636]

Motherboard: ROG STRIX X670E-A GAMING WIFI
CPU: Ryzen 9 9950x3D
RAM: 2X24G G.Skill Trident Z5 RGB (Part number F5-7200J3646F24GX2-TZ5RW)
GPU: AMD RX 9070XT
PSU: Seasonic Vertex Focus v4 GX1200 ATX3.0

I am building a new computer. However, I did not check that the compatibility between the Motherboard and the RAM. The CPU and GPU are QVL, but the RAM is not supported officially. However, upon contacting the supplier, they assured me that the RAM would function on this mobo.

After pressing the power button, the fans and RGB all function, but the RAM Q-LED comes on, and after 5-15s, it changes to the CPU Q-LED. I have disconnected everything apart from the CPU, CPU Cooler, and RAM, as well as connectors to the case for the power button.

Which part is causing the problem? And how can I diagnose this?

I have tried clearing the CMOS (by pressing clear cmos button w/o power for 10s), and flashing the BIOS, but nothing has allowed it to go past POST.

Rams are populating slots A2 and B2?

How are you cooling the processor? If I were you, try, and breadboard the system with just one stick of ram on slot A2, rest the cooler on the CPU's IHS(without any mounting pressure) and see if you're able to get the system to POST with the iGPU.

Thanks for the answer,
I am trying ATM with only 1 stick of ram in both A2 and B2, I am using an AIO cooler from Valkyrie. I have tried to reseat the cooler without mounting any pressure, but I am still unable to get to POST, and the system is still stuck in the same senario.

If the CPU light is the only one on the motherboard thinks the problem is with the CPU. Check the pads on the bottom of the CPU and the pins on the motherboard. If all is good there try putting it back in the socket and booting up.

If it's still not working the only thing you can do is either put the CPU in a known working motherboard or put a different CPU in this motherboard. If this isn't possible it's time to get a replacement for one of the two.

Thanks for helping!
I removed the CPU/Cooler, reapplied thermal paste and reseated it, I also checked for damage on the AM5 motherboard socket and the CPU, but the contacts seem all fine. Testing again afterwards still has the same problem.

Solved now, turns out its just ASUS AM5 motherboard stuff. After rebooting countless times waiting around 10 minutes, memory training seemed to work, and I had to do the same process for other stick of ram. Now everything works.
