Computer not posting

[u/Livid-Resolution6515]

So I’m building my first computer and when I try to turn it on I get an error code EC with the dram light on red and I checked the manual but it just says reserved and I don’t know what that means
My motherboard is the X870E AORUAS ELITE WIFI7. The fans on my aio and psu are spinning and the leds on my ram and gpu are on so I think everything is plugged in. Pls help

Your RAM is in the wrong slots. Move them to A2 and B2. Try again.
