Memory as you need to enable multiprotsessings?

[Michael Szalapski]

3 GB is nowhere near enough for multiprocessing.
For multiprocessing, you want at least 2GB of RAM per core you’re using. PLUS at least 1 GB of RAM reserved for other applications and your operating system.

if you are only working in sd, then you may be able to use less than 1gb per core… i work mainly in 720p and use 1gb of ram per core (though i have 16gb of ram and 16 cores — 8 cores are for ae, 8 for other apps, 8gb for other apps).

however, 3gb would still only allow you to use 2 cores, and leaving only 1-1.5gb of ram for a 64-bit os will probably still hurt your performance when the os runs out of ram (as i mentioned, i leave 8gb for the os). when the os runs out of ram, it starts to cache to disk, when that happens, performance will drop significantly.

you’ll probably notice this more often with longer renders, before i had increased the ram for other apps to 8gb, i had noticed performance decreases at about 5-10 minutes into a render that coincided with high disk activity. after increasing that to 8gb, i rarely see that happen.
