Overview

This tool was implemented with TDO to improve its performance when a large amount of memory is needed, such as the new collage, the Multi-Tooth page, and Image Acquire.

This tool patches x86 executables to allow 4GB (instead of 2) of virtual memory on x64 platforms. It is handy for applications that need a great amount of virtual memory. For more info about this tool, click here (external link).

Note: TDO version 12.405e and above. If on TDO version 12.373g and below, please contact TDO support for the memory patch.
