GA-Z170X-UD5(rev.1.0) will not post using DDR4_1 or DDR4_3

[dargz09]

I just purchased a GA-Z170X-UD5(rev.1.0) and I am unable to use Memory Channel B in any configuration. When ever I try to use either DDR4_1 or DDR4_3 the motherboard will try to boot up print out code 55 and then restart doing it all again in a loop. Both of my ram sticks work in DDR4_4 and DDR4_2. Any suggestions of what I can try?
