I have a problem where I get 3 long beeps and 2 short beeps upon power on the case.  The post code prevents the system from booting up.

 

My guess is memory, however if I pull 2 sticks of 4 installed, it won't post either.  Any combination of two dimms won't work either.  I was thinking this system required 4 sticks of ddr4, but the z170 chipset from what I can tell is dual channel and therefore can only use 2 sticks if required.

 

What does this mean?
