Memory Ussage

[Nero]

Hey guys,
So I have been coming across some issues. When I render I get errors on really high poly models that include:
"The render was cancelled due to insufficient memory. Adjust the scene or Render settings to reduce memory usage and try again."

My specs:
Windows 7 Ultimate 64 Bit
Intel Core i7 3.4GHz
24 gigs of ram
Direct x11
Nvidia Geforce GTX 580

How do I go abouts making 3DS max use more of my ram and CPU? I checked them while rendering (before errors) and they aren't being used much at all.

Edit; I tried Vray and Mental ray.

It crashes at 44% CPU usage, and 5 gigs of ram before it goes bye bye.

I dunno, remove some memory. Maybe that'll halp?

Have you gone to BIOS and adjusted anything in there?

Sounds like an issue with 3DS Max you're using, not Windows or BIOS or anything like that.

I was being a dummy and rendering with the 32-bit version......
