Error code 55 on z170

[Lofty2101]

Whenever i try to use my ram sticks on either dimm b1 or b2 it comes up with that error, the following are the results
a1 or a2 - post
a1 & a2 - post
b1 or b2 - no post
b1 & b2 - no post
any a & any b - no post

Is there any solution for this? i have looked online at other forums and none of them helped.

Are you checking each memory stick in each slot?

What is the system board and CPU you are using?

Try to loosen your CPU cooler, I know of 2 system that had similar symptoms that were fixed by that.
