I have found a new free toy today called Rambooster(v1.6), which I am tickled pink with that one can download it at: http://www.sci.fi/~borg/rambooster/ I have not the fastest machine in the world: Win 98se P800 III with 314 Ram, but works well most of the time. But I have a number of applications that run in the background that I do not like to have not running like my firewall, virus alerts etc. If your Poser is crashing and seizing up due to load CPU resources while you render this is the real answer. You can allocate in the preferences the amount of ram you need to get you up over the hump while you render a big scene. The indicator bar will show you when you are getting low as if Scotty on Star Trek is right there saying "We need Moooorrrre Powerrr Captain! You hit the Optimize button and Bang! Nitro-oxide for your Poser (The Fast and the Furious feel) render.
