Notes

1. The minimum memory requirement is one DIMM in U2.
2. The memory installation sequence is U2, U3, U4, and U5.
3. Each bank addresses 512MB of memory with 500MHz UltraSPARC.
4. Each bank addresses 1GB of memory with >=550MHz UltraSPARC.
5. OBP <=4.5v0 incorrectly reports errors as DIMM1 (U2) to DIMM4 (U5).
6. OBP 4.5v9 correctly reports errors as DIMM0 (U2) to DIMM3 (U5).

UltraSPARC Notes

1. The 450-700MHz processors were originally named UltraSPARC IIe.
2. The 550-700MHz processors were renamed UltraSPARC IIi in 2002.
3. The System Board was designed for 450-700MHz processors.
4. The Sun Blade 100 was only sold with 500MHz UltraSPARC IIe.
