well.

1. make sure your computer actually HAS the ram you try to allocate to tekkit/technic.

2.  check the pages for every block you've used. some-say, the blackhole chest-are world-crashers on their own. others can combine to crash the world-for instantce, quarries+teleport pipes.

3.  tiny render? my puny xp can run vanilla with tiny render, even in the nether...

4. all animations off?

5. are you using the development build or the latest STABLE build?
