Memory is like Money: If you have owned a computer for a number of years, you know it is a true statement: you always can use more memory. With today's powerful system software and the newest generation application programs you need more memory, lots of it in fact, to run your computer efficiently.
   Depending on your applications and work habits, you may want to upgrade your Mac to 32MB or 64MB, or maybe more than 128MB, and in some cases up to 512MB of RAM.

What does it all mean?: 168-pin 64-bit 5V 2K-refresh FPM Memory DIMM

  • 168-pin means that the memory module has 168 connections to connect to the DIMM socket on the logic board. Part of the 168 connections are the 64 data bits that are transferred to and from the memory module. Other connections are the address lines and the power connections.
  • 64-bit means that the memory module features a 64-bit data path, thus a single memory access can transfer up to 64 bits or 8 bytes.
  • 5V means that the chips on the DIMM operate with 5V operating voltage, as opposed to 3.3V, another common, but incompatible DIMM operating voltage.
  • 2K-refresh refers to the total number of refresh cycles required by the memory chip to maintain data integrity. Some incompatible memory chips are offered with 4K refresh, but some Mac models require 2K-refresh or less to function reliably.
  • FPM means Fast Page Mode, a memory access mode to increase the memory access speed in certain Mac models.
  • DIMM means Dual In-line Memory Module. This term refers to the two-sided connection method of the memory module to the connector on the logic board.

Choose with confidence: In order to successfully upgrade the memory of your Mac, there is no need to understand all these terms in detail. Simply verify that your Mac model is listed in the above table and select the part number for the memory size (amount of MB) that you desire from the product selection table on the bottom of this page.

Note: The above listed Macintosh models are incompatible with EDO memory. According to Apple, EDO memory can damage the Mac logic board of the 7200-series and 8200-series Macintosh computers.
