It’s DDR2. The machine’s pretty old but not THAT old. It’s a Dell XPS 400 from 2005. I already did some price checking on memory at Tigerdirect. $56+shipping for 2x2GB looks like the cheapest, not counting overstocks or used deals. I’ve never actually bought memory used though. It doesn’t sound like I’ll be able to get that much out of it. I think I’ll drop plans to upgrade for now and start saving for a new machine unless I change my mind in the next week or two. I’m about to start a big project. I haven’t used Blender in a while. I was going to be using Blender Internal for most of the rendering anyway because Cycles still isn’t feature-complete yet for animation, but it’s getting closer. It’d be nice to try it out for a few shots.
I’ll probably get in the habit of using Linux more often though, cause it’s definitely faster.
I haven’t really hit max memory usage on Blender anyway so I’m not sure if more memory would really help me. I tend to not do very memory intensive scenes to begin with poly-wise or texture-wise, but I do love using raytraced lighting. I’m actually excited to try out some old-fashioned filmmaking and compositing tricks. I only started considering an upgrade when I realized how cheap it would be to get a better graphics card.
So more memory is off the table for now. I might change my mind when I start doing some bigger-scale painting in Gimp, but that’s probably a topic for another forum.
