@ Gareee ,
I have 4gbs of ram on Win XP pro with the 3gb switch enabled ,

@AnAardvark ,
Yes I am using "texture shaded" for my display just like I do with Poser 7 ,
In Poser 8 I have tried all the different setting EG:
Open GL Hardware/software ,enable hardware shading On and Off
Transparency Display - actual , limit to 50% and enhance multilayer tranparency On and Off ect
and changing these setting seams to have no effect on whether or not I get the out of memory errors :(
Although Turning enhance multilayer transparency doe slow down the UI a bit

BTW I have a ATI RAdeon HD 4850 with 512mbs ram

I have read in other threads about some other people have the same out of memory errors .
