[SOLVED] ASUS x570 TUF + Yellow Debug LED on boot

[PhoNamDuhh]

ASUS x570 MOBO - yellow post light is on when booted, indicates a DRAM issue. Exchanged the MOBO after trying two different types of RAM, tried a 3rd brand on the new MOBO (RAM was working in another computer) still a yellow light on boot.

Ryzen 5 3600 CPU

Tried Corsair Vengeance LPX 3000 and ADATA APG 3000 RAM and set of the Trident Z.

I tried all of them in the last DIMM slot to the right (furthest from CPU), which is the suggested setup for one stick as described in the mobo manual. I tried 2/4 slots as well.

I’ve tried clearing CMOS as well. No luck.

All the wires from PSU to CPU/MOBO/GPU are secured.

Can the yellow debug LED indicate any other issues beside RAM?

PSU - EVGA GQ 850W

GPU - ASUS 1060 6GB

Looks like the RAM should be supported.
