Notes
1. These systems have 32-bit-clean ROMs.
Computers with 32-bit-clean ROMs can
take advantage of more than 8 MB of physical
RAM under System 7 or higher.
2. The ROMs in these systems are not
32-bit-clean, but with the 32-Bit System
Enabler under System 7.1 or MODE32
with versions of System 7 prior to
7.1, they can run in 32-bit mode and
can take advantage of more than 8 MB
of physical RAM.
3. The Macintosh Portable has 1 MB
of RAM soldered to the main logic board.
You can add more RAM using an expansion
card. The Macintosh Portable memory
expansion card can have from 1 MB to
4 MB of RAM. The backlit Macintosh
Portable memory expansion card can
have 1 MB to 3 MB of RAM.
4. If the processor-direct slot (PDS)
is used for other peripherals, the
maximum RAM is 5 MB for the Macintosh
Portable and 4 MB for the backlit
Macintosh Portable, using a memory
expansion card.
5. The PowerBook 100 has 2 MB of pseudostatic
RAM on the main logic board and one
expansion slot. Additional RAM can
be added using a RAM expansion card
for a maximum of 8 MB.
6. The PowerBook 140, 145, and 170
have 2 MB of pseudostatic RAM on the
main logic board and one expansion
slot. The 4 MB configuration shipped
from Apple has a 2 MB RAM expansion
card installed. To expand up to 8 MB,
replace the 2 MB RAM expansion card
(if installed) with either a 4 MB or
6 MB RAM expansion card.
7. The PowerBook 145B, 160, 165c,
180 and 180c have 4 MB of pseudostatic
RAM on the main logic board and one
expansion slot. The 4 MB configuration
shipped from Apple has no RAM expansion
card installed. To expand up to 6 MB,
8 MB, or 14 MB, install a 2 MB RAM
expansion card, 4 MB RAM expansion
card, or 10 MB RAM expansion card,
respectively (note that the PowerBook
145B can be expanded to a maximum of
8 MB).
8. For the PowerBook 165, 165c, 180,
and 180c, we suggest 85ns pseudostatic
RAM. Use of 100ns pseudostatic RAM
results in a performance decrease of
approximately 5-10%.
9. The PowerBook Duo 210, Duo 230,
Duo 250 and Duo 270c have 4 MB of low-power
DRAM on the main logic board and one
expansion slot. The 4 MB configuration
shipped from Apple has no RAM expansion
card installed, while the 12 MB configuration
has a 8 MB expansion card installed.
To expand your Duo, add the appropriate
size memory expansion card.
10. The PowerBook 150 uses Duo type
memory. However in order to add more
RAM, you must first have a memory adapter
installed. The part number for this
adapter is M3179LL/A.
11. The PowerBook 5300cs and 5300c
come with either 8 or 16 MB of RAM
soldered on to the logic board. Either
configuration is expandable to 64 MB
of RAM.
12. The PowerBook 5300ce comes with
a 16 MB expansion card installed.
13. The PowerBook 2300c has 8 MB of
RAM on the main logic board and one
expansion slot. The 8 MB configuration
shipped from Apple has no RAM expansion
card installed, while the 20 MB configuration
has a 12 MB expansion card installed.
14. The PowerBook 190 and 190cs come
with either 4 or 8 MB of RAM soldered
on the main logic board and one expansion
slot. The model that comes with 4 MB
on the logic board is expandable to
36 MB. The model that comes with 8
MB on the logic board is expandable
to 40 MB.
15. The PowerBook 3400 and PowerBook
G3 utilize 3.3v EDO memory.
16. Refer to Apple's own article 24612:
"PowerBook G3 Series: Memory
FAQ" for additional information
on memory expansion for the PowerBook
G3 Series.
17. Due to space limitations, a 256
MB SO-DIMM will fit only in the top
slot. The PowerBook G3 Series (Bronze
keyboard) uses memory similar to iMac
and the original PowerBook G3 Series.
18. The iBook uses 1.25" SO-DIMM
for memory expansion. The RAM chips
must be 3.3v, 66 MHz (15 ns).
19. The PowerBook (FireWire) uses
memory similar in size to the PowerBook
G3 Series (Bronze keyboard) but of
different specifications. Be sure to
use PC100 memory in the PowerBook (FireWire)
to ensure proper operation.
20. A 256 MB memory module can be
used only if the iBook Firmware Update
has been installed; otherwise, 128
MB is the largest capacity module that
can be used.
