Virtual Memory or Virtual Address Space? They are two very different things. Is the error you get an Out Of Memory (OOM)? If so it's VAS not VM.

A couple suggestions that worked for me..but this is the golden question and results are different for everyone.

 

1)Definitely check out CTD guide

 

http://forum.avsim.net/files/file/65-avsim-crash-to-desktop-guide-for-fsx-p3d-fs9/

 

2) Word Not Allowed's Tweaks -- Definitly work picking and choosing what works best.

3) Microsoft Process Explorer program is highly recommended since it will give you a good look at how much VAS you are using realtime.

What aircraft were you flying? A default?

 

Agree in part with I_jayma above except, of course, for the Word Not Allowed tweaks. High settings are the main cause of OOM's and Word Not Allowed's guide has high settings (he may have lowered them since a couple of years ago but I remember even he was experiencing OOM's and had to lower the settings in his guide). Tweaks are bad too for FSX. Word Not Allowed has a good guide but, again, be careful with the tweaks and settings. AVSIM has a good FSX Configuration Guide located to the right of this forum under Hot Spots that should work for most computer systems. We suggest you try those settings instead.

 

As you can see, your notebook is on the lower end of current notebook CPU's - http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-3337U+%40+1.80GHz. So your settings really cannot be too high until you upgrade your notebook or purchase a desktop. Even individuals like me who own a really high end computer (i7 4770K w/780GTX video card) has to be careful with settings as it is easy to run out of virtual address memory (VAS). Here's how you can monitor VAS:

 

Monitoring VAS in FSX or P3DV2 – The freeware or registered versions of the FSUIPC utility will allow you to monitor the amount of VAS remaining during a flight session. This might be valuable in troubleshooting Out-of-Memory (OOM’s).

 

Startup FSX/P3D and then enter the Addon Menu and select FSUIPC. Once FSUIPC is open, click on the Logging Tab and enter 024C under Offset and select S32 under Type. Select where you would like to have the usage displayed. The FS Window is for Full Screen sessions. The FS Title Bar is for Windowed Mode. AVSIM recommends you also check the Normal log file as this provides you information on how much VAS you had to start out with and then it logs usage throughout your flight.

 

The VAS usage is displayed in Kilobytes (KB’s). The value represents the amount of VAS left so, the lower the value, the more VAS being depleted. The max amount of VAS allowed in computers with 64 bit Operating Systems is 4GB’s. This is shared with other applications running in the background on your computer. For 32 bit Operating Systems, the max amount of VAS allowed for FSX/P3D is 2GB’s but this can be expanded to 3GB’s with a switch like the /3GB switch.

 

To convert the KB’s to the amount of GB’s, you should use one of the Byte converters on the Internet like the following: http://www.whatsabyte.com/P1/byteconverter.htm. You will never see 4194304 KB’s displayed as this equals 4GB’s. You might see around 3GB’s (3145728) remaining when you first start up FSX/P3D but that would be unusual. Do not be too concerned with the amount of VAS remaining when you first start up.
