Question PC won’t boot with 2 sticks of Ram

[LloydC99]

Just finished my first build yesterday and have an issue where my pc won’t boot up with both sticks of ram. When both are in slot 2 and 4, it starts but doesn’t boot. When in slot 4 by itself same problem but when in slot 2 by itself it boots up fine. Also both ram sticks are working, tested both in slot 2 by themselves and no issues booting up. I was told to start with 1 stick, go into BIOS, enable XMP, turn off PC and insert the second stick but it just causes the PC to constantly turn off and on again every 2 seconds. Is there a fix by tuning the ram settings in BIOS or is my MOBO faulty?
Components are:
Ryzen 5 3600
Gigabyte A520 auros elite
Corsair Vengeance LPX
Crucial M.2 500gbs
Xfx Rx 570 8gbs
EVGA 600watts Psu

Was this RAM purchased in a two stick kit or did you by two separate sticks of the same RAM?

They came together in a 2 stick kit

I doubt its your mobo, you could have simply got a n incompatible pair of RAM. If possible return the RAM to where you bought it and get another set. Or if you cant contact Corsair for a RMA and get a replacement from them.
