Red DRAM Light on new PC: What should I do?

My build consists of:

Gigabyte X870I Pro Ice (Mini-ITX so only two RAM slots before people suggest changing placement)

32GB (2x16) Klevv Cras RAM

7600X3D

850W Coolermaster SFX PSU

5060TI 16GB (Shouldn’t matter, I’m only running these tests with Intergraded Graphics)

So my issue is when I try to boot my PC up, the fans spin, lights turn on, even the RGB on my RAM kits turn on, but… nothing. It never posts. I feel like I’ve taken this PC apart and put it back together five times over. Re-seated the CPU, tried booting it with one stick in one slot, then changed slots, then changed sticks. Nothing. I’m hesitant to think it’s a RAM issue, because neither stick is working. I’m hesitant to think it’s a CPU issue because no pins seem bent. I’ve let each stick sit in each slot for 30+ minutes, and I let them both sit together for over an hour in case it was memory training. I tried flashing the bios, albeit I’m not entirely sure I was successful as I’ve never done it and I’ve never seen this motherboard do it. I tried resetting CMOS, but again, that’s something I’ve never had to do and this specific board forced you to short it rather than disconnect the battery, so… i believe I did it correctly, but am not 100% sure

I’m mostly looking for any advice. I don’t have a third DDR5 RAM kit to test, so unfortunately I’m limited. Just advice on what I can possibly do would be nice.
