Actually, according to the system documentation, the problem is not
the slots in use, but the number of the DIMMs:

---
Memory modules must be installed in pairs of matched memory size,
speed, and technology, and the total number of memory modules in the
configuration must total two, four, or eight.

It looks like 6 DIMMs are not an optimal configuration, whatever slots
you use ...

Does anyone know why is that?

Thanks.
