Dual Channel RAM doesn’t work but single stick does

[Blixton]

So I upgraded my old 8gb stick of ram with G.Skill Ripjaws 16gb kit, but with both sticks of RAM on the dual channel slots I don’t get a post, just a motherboard RAM error light.
 

I took one of the sticks out, and my system boots just fine. I put both of the sticks right next to each other on the mobo, and it boots just fine (although my motherboard gives me a message to place the RAM in the “optimized” slot, yet boots up fine) picking up the full amount of memory.

 

I benchmarked my system with this configuration and the RAM wasn’t running at its full potential.

I updated my BIOS and installed some drivers on the motherboard, but it still won’t boot with the dual channel configuration. Is there something I’m doing wrong?

 

CPU: i5 8400

Motherboard: MSI B360 Gaming Pro 

RAM: G.Skill Ripjaws V 3200MHz 16GB

GPU: GTX 1060

PSU: EVGA 500w 

 

I’ll add that the system itself is practically brand new besides the old RAM that wasn’t being replaced until today.

try slots 1 and 3 instead of 2 and 4

my guess is a bad ram slot, a cpu mount issue (unlikely with LGA1151..), or a bent pin in the socket.

Unlucky, the motherboard is brand new and I’ve been using it for a few weeks with a 8gb in the second left slot and it’s been working fine

Clear CMOS after putting both sticks in. Use slit 2 and 4.
