Question DRAM light on when RAM is in A2, B2 (preferred setup), won't post in A1 or A2 slots ?

[x4sq]

Hi, I built my first PC over a year ago now, and when first testing it I realized it wasn't posting. I googled what this meant and was informed to try only 1 ram stick, and I tried it in B2, and it ended up working. I ran with only 1 ram stick for a while, and ended up trying my 2nd one in different slots. It only works in B1, and B2, otherwise it won't post. I'll send a list of my specs below here and please inform me if I need to send more information as I'm new to this stuff. I've also been informed that it can be due to bent CPU pins, which I've looked for and don't see any visible to me.

CPU: i9-10850K
GPU: NVIDIA GeForce RTX 3070
MOBO: Asus Prime Z490-A
RAM: 2x16 GB Corsair Vengeance

Thanks in advance, Ryan.
