Running out of Memory under Vista Ultimate

Recommended Posts

I have FSX Deluxe and had it running under Windows XP fine.I installed Vista Ultimate onto my machine and reinstalled FSX and redid the tweaks. Now while it is running it runs better under Vista than it did in XP but it does not run for long. I have exactly the same settings I used in XP and am going through all the missions again.After a while FSX will stop and I usually find a message on the desktop saying that FSX has run out of memory and to close it down and reduce the scenery settings.My machine is a Core 2 6700 with 2GB DDR2 ram and a 8800GTX video card with 768MB onboard. I have increased the swap file from system managed to 3500-5000MB but still get the issue.Anyone else had this problem and know how to fix it and please don't say go back to XP. I want help not stupid comments.

I think with Vista you may need 4gb of memory as the sweet spot. Don't have it just heard that it has tons more services running in it thne XP had so you need more memory.

>I think with Vista you may need 4gb of memory as the sweet>spot.

Also I was running FSX under XP with 1GB with no issue except the laggies. With Vista I have 30% in use.It almost looks like a memory loss issue as it is okay for for a time but on longer flights it does it.

Well doesn't look like a memory issue as when it stopped it was only using 75% of available memory.

I get the same thing with Vista x64. Try slimming down the memory Vista uses. 1. Go to the Windows 2000 DWM (desktop window manager). System - Advanced - Performance - Adjust for best performance.2. Shut down anything in the system tray you don't need (I even turn off my anti-virus).3. Shut down the sidebar.4. Shut down non-essential services. I have a batch file that does this for when I run FSX. It shuts down 10-20 services. I will have to post it when I get home. I also have another one that turns the services back on.

I wuold check the case for overheating - clean all fans and airflow ports. Then check the RAM is not faulty - use Memtest.FS remains the single biggest drain on system resources, no matter the OS. If any part of the system shows weakness, that could be it. Alternatively, try some different video drivers.Allcott

Delete the swap file, reboot, make a new one. You most likely have the old XP swap file with stuff in it. It's always safer to tweak the registry to clear the pagefile.sys upon shutdown, even though shutdown will take longer.

Fans work fine as does memory as the going back to XP works fine with no hassle (Dual bootable) It is just Vista that is the issue.

I have seen FSX use tons of Video memory as high as 360mb of video memory and over 2gb of main memory thats in XP so Vista may be a lot worse.Vista can't access 4gb ram sounds off to me but who knows I have no ideal about what Vista will do or not do.

"Now while it is running it runs betterunder Vista than it did in XP but it does not run for long." If it doesn't run for long then it cannot run better under Vista.How is that possible?Craig

Explains itself. Also note I asked for help not stupid comments.

I repeat...if it doesn't run for long then it's quite simple...it cannot run better than in XP where presumably it runs till you decideto stop it.

Good grief. Just ignore the troll.Do what I said above. Here are my batch files. The "on" file puts the machine in game mode (turns off services). The "off" file puts the machine back to normal (turns on services).Run the "on" batch file right before running FSX. Run the "off" batch file after you're done flying.You may want to go through them and make sure there aren't any services getting turned off that you need...like the IR service, etc. I left the print spooler on so you can print flight plans.This is my first pass. There are probably another 5-10 services I could whack..."on" file:http://forums.avsim.net/user_files/166293.txt"off" file:http://forums.avsim.net/user_files/166294.txtThe "off" file will sometimes hang while it is turning the Sidebar back on. Just close it and run it again. That clears it up.Also, Vista 32 bit can access 4 gigs of RAM. But it will chew some of that up, and I think it will only allocate 2 gigs per process. Vista x64 will access terabytes (and more) of RAM.Also, don't worry about your swap file...FSX does not like using the swap file. I have a 1 gig Turbocache flash drive that Vista is using to cache the swap file (Readyboost)...this isn't helping my FSX memory problem. I'm pretty sure that FSX knows it would slow to a CRAWL if it started swapping, so it just shuts down when it runs out of physical memory.

Thanks. Did not help. I have about 75% memory free when the message comes up, I am suspecting the missions because it is always exactly in the same spot in the mission that I am flying (Hawian). Some other longer missions have worked fine but this one barely lasts 4 minutes. Have yet to have it happen in free flight but have not done many long flights.

Is this perhaps related to other Core 2 Duo users reporting running out of memory using FSX under Vista? If that is the case, and it is an actual fault/bug, then there's not too much to do apparently. I don't use either Vista or a Core 2, just mentioning other rumours that I've seen elsewhere.

Hi,the BUG is not related to Windows Vista only, I got the same error message under Winows XP SP2 before Vista was released.Problem is more related to your graphics settings. I got the bug if I set all slider to the right.Try newest nvidia driver 100.59 and try to reduce Mesh and or Water details. Should help.Have a simmilar system than yours, now with dual boot (Vista and XP).

Hello, I'm running into the same problem... I have Vista Ultimate 64bit. the Evga 680i, EVGA 8800gsx with 100.59 drivers, E6600, and 2gigs of ram... I was able to fly from PHX to TUS and on decent FSX gave me this error... I tried a flight from MRY to SJC with the same result on decent with the same error. I was flying the EMB120. For my setting pretty much everything is to the right except traffic. I'm able to obtain smooth fps around 15 locked and look really good... Windows XP was a bit better in the loading for texture around my A/C. I'm assuming the memory dump or whatever is happening has something to do with it... Hope to hear more, or a fix soon... Take Care

hmmm interesting, 2gig of memory should be fine, what is your virtual memory set at? Its a horrible way to run things but could be a quick fix for you, i recommend at least 2 gig's of virtual memory on your fastest drive. Turn of indexing on all your drives. Install diskeeper with the autodefrag and ifaast on, so that it will move your most used files to the head of the drive. I believe it will run on windows vista. but i would check isohunt.com. Actually i looked and there is a build for vista. Let me know if that helps

Hello, thanks for everyone that has read this and offered help... Still having the same issue... Just to update... I have a clean install, and only one hard drive 375 gig 7200.10 western digital, I think... brand new... I installed the new MD-11 which looks pretty good for quick boot up and fly aircraft... No PMDG, but it will do for now... Wish I could fly it... can't even get to the end of the runway... I tried the 100.54 drivers and same result.... Thanks, hope most of you are able to enjoy FSX.. I'm hoping the upcoming patch will help, or someone will have a key to this issue...

You might try running Windows Defender...make sure you don't have any processes hanging around that shouldn't be there.You could also try running FSX in a window while Task Manager is running. You could then verify if FSX is really using all available physical RAM, and the out of memory message is correct, or if FSX is crashing and the message is misleading.If it is the former, then you may need to turn some settings down...though I run with stuff up pretty high on 2 gigs in Vista...If it is the latter, then it may not be memory.One last thing...burn yourself a MemTest CD...boot off it, and let it run overnight. You just want to make sure the 2 gigs you have is working correctly.

Okay I've witnessed this 'problem' now on both of my machines. Its not a pagefile issue and its not what family photo you have on your desktop, and its definately not a grammar issue. The common item seems to be Vista Ultimate x64 and GeForce 8800. I have used all available driver sets, and have not messed with any of the FSX settings or added any third-party addons. Machine 1:HP XW8200Dual - Singlecore Nacona 3.6GHz8GB DDR2 PC 3200146GB 15K U320 diskEVGA 8800 GTX 100.59Vista x64 Ultimate - 16GB pagePerfmon shows the fsx*32.exe at 1,042,399 at the well documented out of system memory error.Machine 2:HP XW8400Dual - Dualcore X5150 2.66GHz4GB FBDIMM DDR2 PC320072GB 15K SASEVGA 8800 GTX 100.59Vista x64 Ultimate - 8GB pageAgain as soon as fsx*32.exe crossed the 1GB memory line, BOOM! She goes down.I realize that the x64ness of the OS is buying us ABSOLUTELY nothing when it comes to FSX cause it has to run in WOW64, but I am postulating that WOW64 is actually causing the issue rather than helping. Can anyone speak to running a <4GB box with VISTA 32bit ulitmate and similar video but NOT experience this crash?? I don't want to downgrade my workstations until this is proven to be the case.

Hey, Good find, hmmmm interesting... I actually had to RMA a memory module due to incorrect info on manufactures website... I'll have a 4gig machine next week sometime I hope... New Egg is pretty good about turn time... I will check out and re post when I'm back up and running... Hope by that time there is a solution... Take Care, and happy flying...
