[maxx0531]

Hello

Just finished building my workstation.
have checked all components in other builds.
when boot up, I get no post
only EZ debug LED
signalling DRAM
but I have checked RAM compatibility
and it should be compatible with the board
I dont have any other RAM
so I cannot check
what should I do?

im on a MSI B450 GP
Ryzen 5 2600
And a Crucial Ballistix Sport LT - DDR4 - 8 GB , 2666 MHz / PC4-21300, CL16-18-18, 1.2 V
