72-pin Memory SIMM

	The 72-pin 32-bit SIMM is the standard memory SIMM for the second generation Macintosh models. These SIMMs come in 1MB, 2MB, 4MB, 8MB, 16MB, or 32MB sizes. The BigSIMM is available in 64MB or 128MB size. Depending on the Mac model they are installed individually or in pairs to achieve a 32-bit or 64-bit data path, respectively.

MicroMac 72-pin Memory SIMM Benefits: Guaranteed compatible for your Macintosh model Free technical support for memory installation questions 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 application programs you need more memory, lots of it in fact, to run your computer efficiently.    Whereas a Mac with 16MB or 20MB and System 7.5 allows you to comfortably run one or two smaller applications, you need 32MB or 36MB to run System 8.0, a couple of standard applications, and a memory hungry web browser, like Netscape. You need even more to handle large Photoshop or other graphic files or to design web pages and preview them simultaneously in several browsers. Why do I sometimes need to install the SIMMs in pairs?: The Centris and Quadra 68040-based models, as well as the Performa models have a 32-bit wide data path to the memory. The memory in these models can be upgraded one SIMM at the time. For better performance the first generation PowerPC-based Macintosh models have a 64-bit wide data path to the memory. These models require that the 72-pin memory SIMMs are upgraded in pairs.

System Requirements, Data Path Width and acceptable SIMM Sizes:

Mac Models	accepts a single 72-pin SIMM	accepts up to two individual 72-pin SIMMs	accepts up to four individual 72-pin SIMMs	accepts one pair of 72-pin SIMMs	accepts two pairs of 72-pin SIMMs
