Skyrim Enboost configuration help

[ShijoriX7]

I have a laptop.

Windows 10
740m 2gb
6 gb ram

I have 255 active plugins.My problem is sometimes my game crushes to desktop.I can't solve it with bug fix mods.I tried using ENBoost but I must have done something wrong.

How should I configure my enblocal.ini for the best performance?

Use guide/description of ENBoost at Nexus site page, it contains everything.
