Quote - well I am having alot of out of memory errors with P8 which i dont have with P7 and so i am just trying to see what is different between poser 7 and 8 :)

Funny thing is some of these P8 out of memory errors occur after P8 has finished a render lol

SO it had enough memory to complete the render but not enough memory to return to the preview window? lol
Must be a memory leak or just bugs that need exterminating .

I am looking forward to the SR1 :)

Are you using "Texture Shaded" for your display? Poser 8 is a lot more aggressive about using shader trees (it uses transparencies, for one thing), and these texture maps have to go through main memory before going to the video card.
