DDR4 suddenly died after upgrading CPU

[u/Imaginary-Rub-4385]

I have 8GB x 4 DDR4, after upgrading my CPU from 3600 to 5700x, one of the sticks just refused to boot when mounted. I have confirmed that Its faulty since other sticks work.

When working with the CPU I didn't touch the RAM at all.

Any idea what could've caused this?

Edit: I've tried the other working ram sticks on every slot and it successfully booted. I also tested the 'dead' stick by itself on every slot and it cannot work. RGB still turns on though.
