Memory Notes

1. The minimum memory requirement is two DIMMs in any bank.
2. The 16MB DIMM uses 10-bit column addressing and was not sold.
3. The 32, 64, 128, and 256MB DIMMs use 11-bit column addressing.
4. If 10-bit and 11-bit DIMMs are mixed, either pair will be ignored.
5. The 256MB DIMMs are not supported in the Ultra 5.
6. Memory speed is 60ns if 50ns and 60ns DIMMs are mixed.
7. UltraSPARC IIi speeds >=360MHz support 50ns memory speed.
8. System Boards 375-0066, 375-0079, and 375-0115 support 50ns memory.
9. OBP >=3.25v3 is required when Micron MTxLDxx72FG-5 series EDO DIMMs are used with 360MHz, 400MHz, or 440MHz CPU modules.
