Color coded. Slot closest to CPU first, and the matching color slot next.

You are in single channel then.In this case I think it was the operators fault. The system may be too weak for maximum performance, but it has been working fine running at good speed with no significant heating problems since I removed 16 GB of memory and installed the remaining 16 GB in the correct slots. By working fine, I mean, no more over heating and no more freezes - no troubles - and it will be some time if ever before my actual need for memory exceeds the 16 GB installed.
The ASUS documentation does indicate that 32 GB is a heavy load for this board and suggests the correct memory slots to use. Would have saved me a lot of grief if instead of suggesting, the manual would have said something like, "Use memory slots in this order."

Edit Add: The correct memory slots on the ASUS MB are slots 1 & 2 nearest the CPU.
