I was looking at how FSX utilises RAM and pagefiles as I was flying. I peaked at 1.72 gb on my page file, and memory in the high end of 2gb. This is with a drive totaly dedicated to FSX software only. It is a 74gb Raptor with a 3gb page file system managed. The drive is working constantly, but not thrashing about looking for files. I have 2gb of Corsair DDR-800 memory running at 5-5-5-12 2Tcmd. My cpu is a Core2 Duo E6600 overclocked to 2.81 so far (been having trouble going higher). My OS is XP 32bit, and I'm running FEX, ASX, and GEX. I plan on getting UTX soon. My questions are these; would it benefit me to upgrade to 4gb of RAM, and what is the best way to optimize my page file? I also have a spare 200gb drive that I use for Megascenery Hawaii X. I thought about putting all scenery files on it (FSG and the like). Thanks for your help.

I dont think more memory will help, since Xp cant address past 3 and the uuper end of the 4gig is used for videocard and peripeheral memory mapping, What i would like to know is for someone with 3gig or more of memory to use memstatus and tell us where FSX peaks at, so far ive only seen results from those with 2 or less

Ok, then what do you think about 3gb of RAM? Maybe that will give a slight boost enough to limit the pagefile activity. Thanks for the reply. I do have XP 64bit which my FS9 runs on. Maybe I can start FSX over with a RAM upgrade.

I've got the page file on one physical drive and FSX on another.That way, both can be active without waiting for each other.. you might try it as a test. If the page file activity does not bother you, there may be no reason to upgrade..

Thanks Bert. I'd like to try that. How would I go about putting my page file for FSX on another drive? That might be good for my Megascenery PNW for FS9, which runs terrible.

At least it does not seem to on my system. I believe what I see within the Task Manager, but not Memstatus.

The page file is the Windows page file..To move, first defrag your drives, then Control Panel, System, Advanced, Performance (Win XP)

Hey Bert, I don't mean to beat this to death, but are you saying that I can create a pagefile for all of my drives on just 1 drive? I can set just 1 page file and select no paging file for the other drives? I take it the others will just use the one? Thanks Bert.

Windows allows you to designate space for a pagefile.The default is on the C: drive, but you can choose freely on which drive you want it.I guess you could assign space on multiple drives in which case Windows would use the additional space as needed.. this is not usually done, however.Some users, myself included, assign a fixed size (in my case 4 GB).This is based on the theory that Windows does not need to go looking for space as applications need it.Experts often recommend to let Windows manage the size instead. Just make sure that the assigned drive actually has the free space required !

I have a Dell Quad Core 3.46 GHtz, with dual 8800 GTX cards and nothing on it be FSX and 2 GB ram. My CPU runs at 30% (with FSX) and my memory started out at 65% and then climbed to 90% after shifting views and eventually crashed if I heep on looking around. I added 2 gig of ram and it made NO difference. I am still at the same CPU and 65% memory levels and I do crash on low memory if I push the system with many quick externals views.I know the 2 GB of ram HAS to help, but I don'e see it.

Do you have the /3GB boot.ini fix applied?Search for /3GB on this forum..
