i tried all your suggestion,
Well, you have not tried all of my suggestions,
You can open the LOG file before you start the rendering and post the information from the LOG file here.
8GB of RAM may be ok, but honestly 16 is better for large scenes like yours and 32 is best for large scenes.
Clearly something was added to the scene at some point that is causing the failure. It is not possible to guess what that is.
It has happened several times that a strange texture format or strange name of a texture can cause a failure. This happens with imported geometry from 3D warehouse sometimes.
Only thorough testing can reveal the problem.
1. have you tried rendering only a small portion of the scene, for instance, even render only a single object like one building, yet the scene still fails to render? Then add back one or two objects at a time testing rendering ability each time?
2. have you replaced the sky with physical sky and it still fails? Will it render if you hide all geometry and only render the sky? If it still fails, then there is clearly a problem piece of geometry or file or texture in the scene and you will need to identify where it is.
3. have you systematically eliminated all geometry from the scene, rendered a test image, then slowly added back (enabled visibility of the layers) of the scene geometry piece by piece until hitting the failure point?
4. have you tried starting a clean new file, and copy-paste-in-place items one-by-one into the clean new scene and run small test renderings until the scene fails?
5. have you applied light emitter to curved geometry? If it is applied to too many faces it can fail.
