    MAXIMIZING my RAM

    Panthers Edit

      So I have a new PC WINDOWS 7 64-bit DELL Precision T7600

      64 GB of RAM- and when I render it typically tells me it is only using 8 - 11% of the RAM

      I thought I had my prefernces set up correctly - any insight and tricks into using ALL of my RAM would be awesome.

      This box typically only renders AE files... and I'm afreaid I am not getting my 64GB worth

          Long and short answer: You are using a temporal effect or feature that causes AE to revert to single process rendering. Refer to this:

           

          After Effects Help | Memory and storage

           

          Beyond that there is no way to enforce more memory usage or better CPU usage. AE takes what it needs given on a specific situation and that is that. also search the forum for past discussions on "ideal multiprocessing settings" or "optimum PC".

            The temporal effect reason makes a lot of sense- it took a little more work to find a simpler explanation for me to understand.

            Considering the effects I am rendering with- that seemed like a good explanation.

             

            Searching the forum for  "ideal multiprocessing settings" or "optimum PC" yielded no results.

             

            But today I am rendering 1080i  quicktimes- flipping the frame rate to 29.97 and creating .avi files with the MATROX HD I-frame codec

            (codec&format is required for files for the "Crossfire" clip player by Click Effects in our control room)

             

            So this seemed like it should be a simple enough render to take adcantage of my 64GB of RAM- but it has used 7 - 10% of my RAM only.

            (I cant seem to post the image of the 7% used of 63.9GB image like the above picture for some reason)

              @Panthers, The machine is a great workstation but what you have is over mounted for the adobe products..  If you want to use more ram, change your project bit-depth (default is 8bit) and/or work with larger comp sizes (3-5k).  As @Mylenium stated ensure that the effects you are using are multi-processing friendly in order to max use of multi-processing.

               

              Hope it helps

                You are converting framerates. That is a temporal operation. And simple limitations from the primordial age of computers will prevent multiple programs from writing to the sam, file, anyway. So you can only process one file at a time and all frames sequentially for that matter, which easily explains the limited use of your resources.

                  That message about "11% used" is only referring to the RAM used by the foreground application; it has nothing to do with the RAM used by background rendering processes, et cetera. In other words, ignore that message; it's misleading.
