Memory and Virtual Memory

Recommended Posts

Hi,Not sure this is the best place to ask this, but I couldn't find anything.I'm a UNIX systems admin, so I don't work with windows all that often. About the only reason I have it installed on my machine is for Flight Simulator. However, I do know my way around well enough, so pretty much anything you tell me I should be able to figure out.So I had 1GB of RAM, and noticed a lot of swapping, especially in heavy AI areas (I use all the PAI packages) while using the 737NG. Along with Active Sky, I have UT Canada/Alaska and the FSGenesis meshes as well, so I can see why it's sucking a bunch of RAM. All RAM was being used according to the process manager.I decided to get another gig of RAM, so I now have 2GB. Windows sees the 2GB just fine according to the process manager. However, it still starts throwing stuff into the swap file, but now it does well before all available physical memory is used up. I was swapping and thrashing like crazy, and I still had about 950MB phys RAM free.Anybody have any idea how to force windows to use the physical RAM before the swap?? I am tempted to just turn the swap off, since Flight Sim and Active Sky (the only 2 programs that are ever running at the same time) shoudln't ever take up all 2GB.That being said, I'm not so sure that's a good idea either.Any thoughts??Thanks-stefan

Hi there Stefan,OK i see your problem.To disable your swapping perform the following.Right click on My Computer and goto properties.After that Select the Advanced Tab ; in that tab click on the settings button in the performance label.Then select the Advanced tab.Now you should see that at the bottom there is a button in Virtual Memory called Change;clink on change.Now you should be able to see all the drives on your computer.Click on the 1st drive enlisted then select the No Paging File radio button and then click on set.Now perform the same steps for all the drives.Now your computer will only use your system RAM.Cheers,-NavneetFS 2004 Version 9.1AMD Athlon 64 3000+ATI Radeon 9600 128MB - Anti-Aliasing 6x512MB PC3200 DDR400 Kingston RAMWestern Digital 30 GB - Seagate 8.4 GBHp CD12 CDRW - Pioneer DVD ROMLG Flatron 775FT 17' MonitorCreative SBLive!

I take it that you use WINxp.If that's the case,disabling the paging file isn't going to help you.I have been reading a lot of threads about XP memory management,and in every single one,it is stated how PF and VM dependent WINxp is.So the more PF you alocate to windows,the better it's going to run.Disabling totally will be just stalling Windows.Check this thread here,it might shed a bit of light.>> http://www.osnn.net/articles.php?action=show&showarticle=99 (it was previously posted in another thread in this forum,can't remember which one though)In any case,disabling PF is really not such a good idea.Memory management is very diferent than,let's say Win98.So my suggestion is,don't disable it,and moreover,if u have ample disk space,augment the PF allocation.I hope it helps a bit.Regards_______________________________Georgios Arkouzis http://www.ivao.org/data/images/flags/waving/small/GR.gif SX077http://www.precisionmanuals.com/images/forum/800driver.jpg_______________________________
