Long story short - I am rendering some high res video (3200x1800) with some filters in Sony Vegas Pro 13 using CUDA. The source video is uncompressed and when I render the final video project to MP4, the CUDA code dumps everything it processes into pagefile.sys, meaning that I require 2TB-3TB of virtual memory to finish the render. In Windows the maximum pagefile size I can set is 716800 MB (700 GB) - I want to know if it is possible to manually make it as large as 3TB on a single partition? When I set it to 'System Managed' it won't even expand beyond my RAM capacity, which is pointless. I have got around the problem by creating 8 partitions that are 700 GB, and setting up a pagefile on each. While this works it is not the ideal way to have my 3TB drives partitioned - I will have to set them back to to a striped array to capture video footage again. So.. can I make a pagefile larger than 700 GB in Windows 8.1.1 x64?
