[SOLVED] DRAM light despite 2 ASUS mobos, 2 AMD CPUs, 4 RAM sticks

[Aren Cambre]

I have two identical AMD Ryzen 5600G CPUs, four 8 GB RAM sticks, and two ASUS motherboards. No matter what combination of any of these I use, I get no response other than things power on (motherboard-driven fans spin) and the DRAM light on the motherboard.

Thanks to the DRAM light, nothing else happens.

All these components are new in box.

The ASUS motherboards:

• TUF GAMING B550-PLUS (WI-FI)
• PRIME B550-PLUS

The RAM:

• Corsair Vengeance LPX 16 GB (8 GB x 2)
• G.Skill F4-3200C16D-16GVKB

Yes, the RAM is seated properly. You can't see the PINs.

I can reproduce with nothing connected to the motherboard except case (fan/switch/etc.) cables, CPU cooler cable, and main power-supply cable. I don't even have my m.2 drive connected.

I've tried paired combinations of RAM and all four sticks individually, in the gray RAM slot B2 (per Asus's instructions, that's where you put a single stick).

I am scratching my head. How could four brand new RAM sticks all be bad? If the problem is the CPU or motherboard, how could all possibly be bad?

I found a second power connector that I completely missed. Hooking it up solves everything.

I used to be a VAR in the late 1990s, and my frame of reference is the single, large 24-pin power connector. I didn't realize these now have a second power connector!

Do the motherboards have a new enough bios to support a 5600g?
