   Odds are the memory "latches' at the middle of the board didn't fully engage.

Meaning, try pressing down on this end to seat the mem fully.

Too, if you had to move the mem from A1+B1 to A2+B2, be sure to reset your BIOS after moving but before booting up.

	2 RAM modules should be installed in slots A2 and B2 which that image also states. The only time you need to use A1 and B1 is if you are using 4 modules. There is no way around having to pull the RAM. Its unfortunate but necessary to troubleshoot RAM issues.

	Hello i have AsRock X370 SLI Killer board with 1700. And this ram: RAMs (3000Mhz): https://www.amazon.com/Corsair-Vengeance-3000MHz-Desktop-Memory/dp/B0134EW7G8 I have put one in the A1 ram socket (nearest the CPU) and one to the B1 socket, according to this: https://s16.postimg.org/cbdcvvcwl/image.jpg I tried to start it up, ok, went to the bios and i see that the ryzen on its first page of UEFI bios says i have 8192 MB ram... and it sees only the ram in the b1 socket and also ranks my system as single channel... (Altough i have 16 GB of ram, 2 sticks, dual channel, properly plugged to the RAM slots. WTF is this...? Im pretty sure i pushed both rams fully, was checking it before i mounted my big scythe ninja 4 cooler. Also currently it also looks like both rams are plugged fully in... Whats the problem...? (i would really love to avoid unpluggin and replugging the ram in the 1st slots that it doesnt see since i would have to remove my big cooler and it was difficult to mount in the first place... wheres the problem?
