          When you assign RAM to background processes for Render Multiple Frames Simultaneously multiprocessing, you choose from a small number of options in the RAM Allocation Per Background CPU menu. But you're not limited to the values in this menu. They are just presets. You can change these presets in the text preferences file.

           

          For example, you could change the value for "MP - Allocation Per Background Process Preset V" to "4.000000" instead of "3.000000" to create a preset value of 4GB. Then, you could assign 4GB to each background process.

           

          Here are the relevant lines of the text preferences file:

           

          ["MP - CS5 - 4"]

                  "MP - Allocation Per Background Process" = "1.500000"

                  "MP - Allocation Per Background Process Preset I" = "0.750000"

                  "MP - Allocation Per Background Process Preset II" = "1.000000"

                  "MP - Allocation Per Background Process Preset III" = "1.500000"

                  "MP - Allocation Per Background Process Preset IV" = "2.000000"

                  "MP - Allocation Per Background Process Preset V" = "3.000000"

           

          For information about the preferences file, including its location, see this page:

          Keep in mind that Adobe doesn't officially support making changes to the text preferences file, so be sure to be careful about making changes, be sure to make a backup before you make changes, et cetera.
