Cpu ddr error light

[beastintheeast]

I have a Msi z590 gaming carbon and I sold my old cpu a 10900k and replaced with a 10500. I'm giving it to my daughter so she don't need nothing crazy and I needed a little extra money. The ddr light is orange and the cpu will flash red. I've tried reseating the ram and cpu. The cpu is on the supported page for the board and the ram worker previously so im not sure why now. Any ideas would be greatly appreciated. The debug led just cycles codes so I don't know if it's just checking for problems but it doesn't stop at one or two. There's lights on the side for cpu, ddr and vga and those are what I was referring to
