Warning: 64MB SIMMs using 16M by 4 bit chip (64M bit
technology) are not available in the market and are not
formally tested by AOpen quality test department yet.
However they are supported by design specification from
Intel and they will be tested as soon as they are available.
Note that 64MB SIMMs using 16M by 1 bit chip (16M bit
technology) have chip count exceed 24 and are strongly
not recommended.
Tip: 8 bit = 1 byte, 32 bit = 4 byte. The SIMM size is
represented by number of data byte (whether with or
without parity), for example, the size of single side SIMM
using 1M by 4 bit chip is 1Mx32 bit, that is, 1M x 4 byte=
4MB. For double side SIMM, simply multiply it by 2, that is,
8MB.
