MXL5: Macintosh System Memory Requirements

 * }

-

The information in this article applies to:


 * Microsoft Excel for the Macintosh, versions 5.0, 5.0a
 * Microsoft Excel for the Power Macintosh, versions 5.0, 5.0a

-

SUMMARY
The amount of memory required by your Macintosh and by Microsoft Excel can vary depending on the following items:


 * The version of Microsoft Excel that you have installed: that is, Microsoft Excel for the Power Macintosh, Microsoft Excel for the Macintosh (68K), or Microsoft Excel for the Macintosh and Power Macintosh (a fat installation).


 * The type of installation (that is, whether you are running a shared installation across a network or a local installation)
 * The state of the Virtual Memory setting (it can either be On or Off)
 * The state of the RAM Doubler extension (it can either be On or Off)
 * The setting for the Preferred Size of Microsoft Excel (this option is set in the Get Info window)

MORE INFORMATION
The following table outlines the approximate memory requirements for your computer system and for Microsoft Excel under the given scenarios.

In most cases, the values listed in the "Memory Heap to Run Excel" column should be the default setting for the Preferred Size.

NOTE: Having Virtual Memory or RAM Doubler turned on will not greatly affect system memory usage on a 68K Macintosh or a Power Macintosh running Microsoft Excel for the Macintosh (not Power Macintosh); therefore, these scenarios are not shown in the table.

The large variation in system memory heap and Microsoft Excel memory heap on a Power Macintosh occurs because of the way program code is handled on these computers. For additional information on how virtual memory is handled on a Power Macintosh, please see the following article(s)in the Microsoft Knowledge Base:
