This article contains the following PowerBook G3 Series frequently asked questions (FAQ) regarding memory, with answers to those questions.

Note that they pertain to the PowerBook G3 Series models that were released in September, 1998.

1. Is it possible to add more memory to the system?
2. What is the maximum amount of memory that can be installed?
3. Are they special memory modules or standard SO-DIMMs?
4. Can memory from the original PowerBook G3 systems that were introduced in November 1997, be used in the new systems?

Answer : Yes. There are two slots for memory on the daughter card that also houses the processor, cache, and ROM. The bottom slot is usually filled by the factory, which installs the base memory of either 32MB or 64MB. The top slot, which is accessible to the user, is open if the system comes with 64MB of memory or less; the user can install more memory in this slot.

Question 2 : What is the maximum amount of memory that can be installed?

Answer : The system supports up to192MB of RAM using standard 64 megabit-based SO-DIMMs.

Question 3 : Are they special memory modules or standard SO-DIMMs?

Answer : Standard SO-DIMMs can be used. We recommend choosing memory that has been tested and approved for use with the new PowerBook G3 Series. Check with the memory manufacture to verify this.

Question 4 : Can memory from the original PowerBook G3 systems that were introduced in November 1997, be used in the new systems?

Answer : No, the memory types and sizes are incompatible. But memory from the PowerBook G3 Series that was introduced in May 1998 continues to be compatible in the new configurations.
