168-pin 5V EDO Memory DIMM
with Parity

The 168-pin 64-bit DIMM with parity is the preferred memory DIMM for the above mentioned Power Macintosh-based Apple Network Server models.

These DIMMs come in 8MB, 16MB, 32MB, 64MB or 128MB sizes.

The DIMMs for these Mac models are installed in pairs to achieve the highest performance by employing the memory interleaving technique.

Checkmark Guaranteed compatible for your Macintosh model
Checkmark Free technical support for memory installation questions
Checkmark Economical

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 of server programs you need more memory, lots of it in fact, to run your server efficiently.
   Depending on your server applications and work loads, 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 EDO Memory DIMM with parity

  • 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.
  • EDO means Extended Data Output, 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.
  • parity is one addition bit for each 8 bit of data. This additional bit allows the computer to check for (but not to correct) corrupted data. The computer then typically warns the user about a memory integrity problem.

Why do I sometimes need to install the DIMMs in pairs?: The Apple Workgroup Server models use a memory interleaving technique to access both DIMMs of the pair in short succession to achieve highest data throughput and highest performance.

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 Apple Network Server 500 and 700 models ship with and support parity DIMMs for error checking. Although parity DIMMs are not required, they are recommended.
