How much memory (RAM) can FCS Express use?
FCS Express Memory Requirments
On 32-bit Windows operating systems:
- If the computer is set up in a standard way, FCS Express (32 bit) can use up to 3 GB, depending on how much memory is on the computer, and how many other programs are running.
- If the computer is booted in a special way described in solution 4 below, FCS Express (32 bit) can use up to 4 GB.
- FCS Express (64 bit) will not be able to run .
On 64-bit Windows operating systems:
- FCS Express (32 bit) can use up to 4 GB.
- FCS Express (64 bit) can use up to 128 GB.
If you are experiencing crashes in FCS Express with a 32 bit system or the 32 bit version, the reason may be that your computer system has run out of memory. This can happen when there are many large files loaded in the layout at the same time. FCS Express does not limit the size of data you can use; however, your computer, or Windows, does set a limit.
If FCS Express encounters an error that it cannot handle, it will display the following dialog:
To find out if this was caused by a memory problem, click the link labeled Click here to view or edit the report. You will then see a window labeled Edit Issue Report Contents. In this window, in the section Technical Report, scroll down a few lines until you see the words exception class, like in the image below
If you see the exception class is EOutOfMemory, then you know the program has run into an out of memory situation. You can see more information in this report, too. For example, it also displays how much physical memory is available on your computer (the line labeled physical memory), and how much memory is currently allocated to FCS Express (the line labeled allocated memory).
- Reduce the amount of memory FCS Express needs by lowering the number of undos that the program can perform. By default, FCS Express can perform 30 undos. This number can be lowered (or raised, if memory is not a problem) by clicking on the Application Button, then Edit Preferences, and changing the option in the General category.
- Reduce the amount of memory FCS Express needs by changing your layout design, so that you are using fewer data files in your layout at any given time. If you would like help with this, please contact us at email@example.com
- Add memory (RAM) to your system. On Windows 32-bit operating systems, the maximum you can install in your computer is 4 GB. On 64-bit Windows, up to 128 GB of memory is supported and FCS Express can use all available RAM..
- If you have a Windows 32-bit operating system, and you already have 4 GB of memory, then FCS Express will normally be able to use up to 3 GB of that. However, if you change the boot settings of your computer to enable more than 3 GB, FCS Express will be able to use up to 3 GB. Please note that this switch involves an important operating system file. De Novo Software does not offer any support for changing this setting, nor is any support implied by this web page. This change should only be performed by an experienced IT person.
- To enable 3GB supports on computers running 32-bit Windows Vista or 32-bit Windows 7 or Windows 8, you will need to use the command bcdedit /set increaseuserva 3072. For details on using this, please see http://msdn.microsoft.com/en-us/library/ff542202.aspx.
- To enable 3 GB support on computers running Windows 2000, 2003, or XP, you will need to set the /3GB switch in the file C:\boot.ini. For details on setting up your system with the /3GB switch, please see the documentation on Microsoft's web site, http://technet.microsoft.com/en-us/library/bb124810.aspx. Please note that even though this instruction page indicates that the setting applies only to Windows 2000 Server and Windows Server 2003, it also applies to Windows XP.
