Notes

1. Eight DIMMs form a bank.
2. All DIMMs within a bank must be the same size.
3. The first bank of memory can be either Bank 0 or Bank 1.
4. Install one bank on each CPU/Memory board before installing the second bank on any board.
5. Install the largest density banks first, then medium density banks, and finally the smallest density banks.
6. The 256MB DIMMs require OBP >=3.2v23.
   OBP 3.2v26 fixes 2GB memory bank BugID 4323635.
   OBP 3.2v29 fixes mirrored SRAM identification BugID 4427581.
   See Patch 103346.
7. The Solaris 2.5.1 prtdiag command displays incorrect memory capacity. Install Patch 104595-09 or higher.
8. OBP 3.2v26 fixes 2GB memory bank BugID 4323635.
