How to Speed up Render Time?

[junior_architect]

Hey i am having problems rendering...they areas follows

1. Rendering Time is taking ages (about 30 mins per render) and sometimes crashes, most times it takes ages to respond of even rotate when not rendering.
   Here are the details under Model info - Statistics -

Edges----------------------1715497
Faces----------------------717820
Component Instances--------37201
Guide Points---------------31
Groups---------------------37141
Component Definitions------165
Layers----------------------27
Materials-------------------345

Im guessing I have to decrease Edges and Faces to increase the Rendering speed.

Is there a way to do this?

Thanks.

It would be really helpful if you identified the rendering application you're using.

Oh sorry I am using Vray 1.49.01

I moved it to the Vray forum where it belongs, then.

My money is the pc is running out of ram.
How much ram do you have?
If you have more than 4gb then i would suggest to do the LAA thingie (large addres aware).
You can download it from here. (http://www.techpowerup.com/forums/showthread.php?t=112556)
You can try too "cook" your light engines (IR LC or QM) for separated.
30 minutes is NOT that much time.
I used to render on a E8400, final renders took up to 3 hrs.
