Oddly enough, those out of memory errors have gone away thus far with this new cpu. I have the same amount of RAM I had before (2 gigs). I was able to render a 1536x2048 pixel images with the following settings with no out of memory errors.

Cast Shadows - Turned on
Raytracing - Turned on
Smooth polygons - Turned on
Remove backfacing polys - Turned on
Use Displacement maps - Tuened on
Raytrace bounces - 5
Min shading rate - 0
Pixel Samples - 5
Max Texture Size - 4096
Max Bucket Size - 64

I'm suprised this CPU fixed this problem. It must not be a memory problem. It must be more related to the CPU even though you get a out of memory. Kind of stumped on this one. I normally have to turn bucket sizes and texture sizes on this size of render way down to be able to render. I didn't think Poser 6 was multithreaded but this CPU definately speeds things up quite a bit. Tested render times in Bryce which I know isn't mutlithreaded and there was almost no deference in rendering speeds from my old FX-53 times

Total render time was roughly 20 minutes, I think. Going to try a few more tests. Is there any standard Poser scene out there for benchmarking purposes?

Hmmmm..... Now =that= is interesting.... 'Poser' itself isn't multithreaded, but isn't the current incarnation of the Firefly renderer? That could be the root of that particular bug. A second thread capped off, but like a good thread, it drops a memory pointer into the render every time whatever resource or function trapped there is called; a few hundred unanswered calls would take up a lot of RAM... Jim Burton did a quick scene with Ingenue Vickie and a mirror set up to add reflections and raytracing load to P5 as a quick test how fast a system could render it. A forum search should turn up the link. There needs to be a few more people with different configs testing with X2's and getting the same results, but it sounds as if this might be significant....

I just my new Athlon X2 system (X2 4600+, GF 6800, 2 GB, RAID) so I'm really curious how it works out for others. I had my box configured with Windows 64, not sure if Windows 64 would have much benefit for Poser (or anything else), but it is supposed to support the dual cores better and help memory intensive apps (if you can believe the marketing). I'm still amazed at the raw power of this chip; I just ran Doom 3 at ultra high quality and had Poser render a full frame animation at the same time. Didn't drop a frame! Amazing...
