New PC DRAM issue

[Sir_Ovbov]

So my friend gave me some parts to build a PC so I used PC part picker to see if all the parts work together and it says they do; however when I put it together the DRAM light on the motherboard turns on and the PC doesn't boot or do anything else. I'm not sure if I just got the wrong RAM/ it arrived dead so needs to be replaced or I'm just being super dumb atm so any help would be great, thanks!

 

Specs: 

CPU: Intel Core i5 9400F

Mobo: ASRock B365 Phantom Gaming 4 Micro ATX LGA1151

RAM: Corsair Vengeance LPX DDR4- 2400

GPU: EVGA GTX 1060

PSU: Corsair CMX 550W

Do you have 2x8GB, 2x4GB? Try booting with only one ram dimm. Are they in spaced out slots, or are they next to each other?

I have 2x4GB and they are spaced out on the second and fourth dim slot on the board.

Nvm, I found some 2666 from my brothers old computer so now the DRAM isn't an issue, it just doesn't output anything
