Because the below configurations do not have at least one DIMM for each controller, we do not recommend using them. Two or more interleave sets can now be introduced to the memory controller algorithm which causes very disjointed regions. Memory performance for these configurations is significantly less than configurations meeting balanced or unbalanced conditions. We do not support unbalanced configurations except for 1 DIMM & 2 DIMM configurations.
