Computer has run out of available memory

Once again I got this problem with FSX, started a flight from Karup AB in Denmark to Waddington AB in a Tornado GR4 and everything goes fine, until maybe 10 miles before Waddington then the PC comes up with an error message and says : "Your computer has run out of available memory. Please restart FS and select different Graphics, scenery or traffic settings", and closes Down FSX.
Last year, I builded a new game PC to try to avoid such problems, and after searching on several forums; I followed that advice to make a pagefile (not on prim. drive, but on my sec. harddrive, so I made it on a size on 35 GB ( to be sure it was big enough), and now I don´t understand why this problem still comes.
My PC specifications are:
CPU: Intel i7-4770K 3,5 GHz overclocked to 4,7 GHz and is watercooled
RAM: 16 GB Kingston HyperX Beast DDR3-2400DC
GPU: NVIDIA GeForce GTX780 3 GB ram
Hard drives: Primary Intel 320 480 GB SSD
Secondary Western Digital WD Black 1 TB
Hope that someone can help me with this problem.
