Yellow DRAM light on after installing new CPU

[Sammmmmmmmm]

I upgraded my CPU from an i5-8400 to an i7-9700k. I immediately got a yellow DRAM light and I tried to switch back to my old CPU but the error prevails. I unplugged everything and took it all apart. After putting my PC back together it's still here. I've been doing this for 6 hours and am just exhausted. My motherboard is ASUS strix z370-e gaming, my ssd is Samsung 1 gb, my power supply is evga 650w, my cooler is cooler master, my ram is 1x8 ballistix and a 1x32 teamgroup. I tried switching out the ram in all slots and got no results. Please help I'm tired

Have you cleared the CMOS and then try each individual stick one at a time?

Yes though I'm not sure if I'm clearing CMOS correctly

I tried CMOS a few more times and nothing
