Can a “ram disc” allow longer ram previews?
Has anyone here ever done this?
There are some apps that can allow software running on your OS to use more ram than your OS can regognise, for example if your using a 32 bit OS your restricted to 4 gig of ram, BUT say you have 16 gig of ram installed on your PC apparently these apps (ramdisc etc https://members.fortunecity.com/ramdisk/RAMDisk/ramdriv003.htm ) can access all your extra ram and distribute it in the form of extra ram cache to your apps.
more info here https://en.wikipedia.org/wiki/RAM_disk
This night be just what we need to get longer ram previews in AFX.
Any thoughts?

No, not really.
Keep in mind that the disk cache (which this doohickey seems that it might add to) only applies to standard preview (aka, spacebar play).
The RAM cache (the part of RAM that RAM preview frames are stored in) is contained within the RAM allocated to the foreground process of the After Effects application. This is theoretically limited to 4GB; once you subtract the bite that the OS takes for its UI libraries and such, you’re left with about 3GB. And After Effects will only use a set percentage of that for the RAM cache (which ends up being about 2GB).
Adding more RAM to your system will not increase RAM preview length, unless you had so little RAM that you weren’t able to give that 3+ GB to the foreground application.
Adding more RAM to your system _will_ make it so that you can use the Render Multiple Frames Simultaneously multiprocessing feature without starving your processor cores of RAM.

Oh well, loocks like my reacent switch to working in HD is going to require me to move back to 64 bit then, ok no probs.
Thanks for clearing that up for me guys.
