PHP Code:
Basicallyyou are running out of RAMOne way to reduce the memory usage for the render elements is to write the image to a .vrimg file and then use the vrimg2exr converter to extract the channels
(*) 
Make sure you are using the V-Ray VFB
(*) 
In the Common tab of the Render scene dialog set the resolution to something like 320x240
(*) 
In the V-Ray VFB settingsturn OFF the "Get resolution from Max" option for the VFB, and specify the actual resolution that you need
(*) 
Turn off the "use memory frame buffer" option
(*) 
Turn on the "write raw image file" option and specify a .vrimg file in the field below it
(*) 
Turn on the "generate preview" option
(*) 
After the rendering is complete, use the vrimg2exr tool to extract the render elements as .exr filesYou can find the vrimg2exr tool in the Start menu Programs Chaos Group V-Ray for 3dsmax ToolsThere is also a GUI for it posted in the off-topic section of the forumI think

Alternativelyyou can simply render on a 64-bit machine with 64-bit 3dsmax and V-Ray

Best regards

I am still quite ticked that with a new machine and Windows XP I can't render an image at 2400 x 3600 px! Apparently, with Windows 64bit you are not limited by memory.

Someone out there correct me if I am misunderstanding things.
