How many poly's do you have?
Im only running 4gb ram and seldom experience crashes. It limits my polycount to about 1.5 million.

to see your triangle count in max, go to views > viewport configuration > statistics, then check triangle count and show statistics in active view. be sure its not in the millions.

Your model is way to high poly my friend.
You must lower it. Trees should be within limits, as outlined below;

Small Trees
Polycount: 600 - 1000
Texture: Two 1024*1024, one for leaves and branches (diffuse, spec, normal, opacity) and one for the trunk (diffuse, spec, normal)
Proxy: Two for the canopy, one for the leaf collision (bigger), one for the AI (smaller); the trunk needs to be physicalized for being breakable
IDs: 4 (trunk, leaf, leaf proxy, AI proxy)

Big Trees
Polycount: 1000 - 2000 (for very unique trees you can go up to 5000)
Texture: Two 1024*1024, one for leaves and branches (diffuse, spec, normal, opacity) and one for the trunk (diffuse, spec, normal)
Proxy: One for the canopy; the trunk needs to be physicalized to be breakable (if the trunk cannot break, add one more proxy and don't physicalize the trunk render geometry)
IDs: 4 - 5 (trunk, leaf, leaf proxy, trunk proxy, AI proxy)

Tips from Crydev Dashboard

In outdoor games, vegetation is usually the most expensive part of the level due to the fact that natural levels are populated with many trees. Each tree should not have more than 1 or 2 drawcalls.

Reduce the materials for vegetation objects as much as possible to reduce number of draw calls.
Use only the optimized vegetation shader on vegetation objects
Spend a lot of time to reduce the number of polygons - these objects are drawn multiple times on screen.
Combine textures in one and reduce the number of materials or at least texture fetches.
Add polygons on the leaves to match the texture - this reduces overdraw (use the triangles you saved on the trunk)


Hope that helps you some bud!

Cheers
