1. The minimum Solaris operating system is Solaris 10 8/11 and Solaris 11 11/11.

Memory Installation Notes

1. In dual-CPU systems, install DIMM filler panel 350-1288 in any DIMM sockets that are not occupied by a DIMM.
   In single-CPU systems, DIMM filler panels are not required in empty sockets associated with processor P0,
   but socket D7 for processor P1 requires a filler panel to support proper air flow for cooling.
2. Install DIMMs in the Blue slots first in slots D0, D2, D5, and D7.
3. Then install DIMMs in the White sockets in slots D1, D3, D4, and D6.
4. Install the highest capacity DIMMs first. Install the highest rank DIMMs first.
5. When Dual Rank and Quad Rank DIMMs are installed in the same channel,
   install the Quad Rank DIMMs in the slots farthest from the CPU.
6. Do not mix Load Reduced DIMMs with Registered DIMMs.
