I have written in the past about improving QuickBooks performance by allocating more RAM to the QuickBooks Database Server, especially in later versions of QuickBooks Enterprise 13, and Enterprise 14. Configurations in QuickBooks 15 are designed to permit the QuickBooks Database Server to use more RAM as needed if available without needing to perform the 'boost' procedure(s), but there has been very little we could do in terms of the Client Workstations.
While all versions of QuickBooks (for Windows) remain 32-bit applications, changes made in recent releases of QuickBooks 14 and QuickBooks Enterprise 14 allow you to take advantage of additional addressable memory if you are running on a Windows 64 bit system and the memory is available.
These changes are extremely beneficial if you frequently compile large reports such as all transaction histories or audit trails and your file size is large. Because of various issues (including memory management) with QuickBooks 15, many users are still running QuickBooks 14 versions.
To enable these enhancements in QuickBooks 2014 and Enterprise Solutions 14:
1. Close QuickBooks
2. Make Changes to both the QBW32.exe and QBW32_4GB files in the QuickBooks program folder.
3. Locate the appropriate folder using the following path:
- C:\Program Files (x86)\Intuit\QuickBooks 2014, or
- C:\Program Files (x86)\Intuit\Enterprise Solutions 14.0
4. Locate the QBW32.exe file and rename it to QBW32_old
5. Locate the QBW32_4GB file and rename it to QBW32.exe
6. Restart QuickBooks
Note: In order to accomplish this task make certain to 'uncheck' the "Hide Extensions for Known File Types" option under the View tab of the Folders Options within Windows Explorer in order to insure you are selecting the proper file(s).
You should see improved client workstation performance as the QuickBooks application will now make use of additional memory when warranted. When you couple this action with enhanced QuickBooks Database Server performance via RAM allocation, your QuickBooks performance should be enhanced significantly.
