Insufficient memory issue on Windows 10 x 32 - Vision Point 32 bit build
Last Updated 3 years ago
Insufficient memory (memory is needed not only for DMA stream itself but also for rendering engine) may cause a splash screen problem using our Chameleon camera simulator
The solution consists of 2 parts:
1. Adding an option to Vision Point 32 bit build process that produces software able to utilize more than 2 GB memory (which is default without this option). Starting from Vision Point, 5.0.0.5316 version found here, when starting acquisition process, a log record that reports memory status was added and can be found in the log file as "ullTotalVirtual." For example, a record saying "ullTotalVirtual==2147352576".
2. The following option is added to Windows to allow large memory allocations for user applications. Start 'cmd' with administrative privileges and run the command "BCDEdit /set increaseuserva 3072". The BCDEdit /set increaseuserva Megabytes command can specify any value between 2048 (2 GB) and 3072 (3 GB) megabytes in decimal notation (one can read more about this command here https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/bcdedit--set).
After rebooting Windows and rerunning Vision Point acquisition, please open a new log file and search for word "ullTotalVirtual". With that 'increaseuserva' option set one should see "ullTotalVirtual==3221094400".
