Table C-2 Dimm Bank-To-U-Number Mapping - Sun Microsystems Ultra 60 Service Manual

C.1.6.1 DIMM
The DIMM is a 60-nanosecond, fast-page-mode-style DIMM. Four DIMM
configurations are supported in the system unit: 16-Mbyte, 32-Mbyte, 64-Mbyte,
and 128-Mbyte. The minimum memory capacity is 64 Mbytes (four 16-Mbyte
DIMMs). The maximum memory capacity is 2 Gbytes (sixteen 128-Mbyte DIMMs).
A block of data (64 bytes) always comes from one bank of DIMMs. An error code
containing the address of where a failure occurred, as well as the associated
syndrome, is logged when an ECC error occurs.
There are a total of four DIMM banks in the system unit.
