NOTE:
• If more than two DIMM types are installed in the BL870c i4 or BL890c i4 systems, the customer
will receive a warning indicating that optimum interleaving is not possible and memory may be
de-allocated. Mixing more than two DIMM types is only supported on the BL860c i4.
• If DIMMs are loaded in pairs in the BL870c i4 or BL890c i4 systems, the customer will receive a
warning indicating that the memory is not configured according to the Hewlett Packard
Enterprise loading rules and some memory may be de-allocated.
Once the memory loading rules have been satisfied, all memory installed in the system will be
recognized.
