Poser cannot handle too many large textures. No matter how much RAM you have.

You may be able to fix it by adjusting your render settings. Try turning texture filtering on, and setting the maximum texture size to 1024 or smaller. (See article.)

If that doesn't work, try some of the suggestions in Stew's Firefly FAQ:
