I applied the above tweak earlier in respect to adding the switch in at boot to access the higher amount of ram. 

Poser didnt run any faster BUT it did allow me to finish a render which I'd previously tried a half dozen times or so  with numerous render settings (and failed) including minimal bucket and texture sizes.  i did still have to lower the bucket and texture sizes but not to the same extent, and to my relief this time I didnt get an out of memory error.

I've also dual cpu and have set Poser to run from CPU 1 rather than spreading the load across both that way if I am also in PS doing something or Bryce or Daz Studio I can set those to run from CPU 0 and not suffer any noticable performance degradation in those apps.
