Question Motherboard memory problems

[USMCrules02]

So I recently have been having ram issues and have obtained a brand new set of ram from g skill but I am still have the issued of trying to boot into my PC. My os is corrupted and no matter what I do to boot into usb the PC will start them get stuck and give me error codes 49-53 which are all ram related (like no usable ram detected or ram instillation error) the PC was working fine until I upgraded to the 9900k now nothing seems to work even if I put the i3 back it just won't boot. Any suggestions for possible fixes.

EVGA z370 classified k
I9 9900k

2x8 gb gSkill ripjaws 3000mhz

Did you make sure the ram was compatible with your motherbd?
Their full list for your board is here

Have you upgraded the bios> the 9900k needs a minimum version of 1.08

I can't get it too boot into windows but it then freezes and yes the ram is compatible and the bios is up to date.
