March 18, 201016 yr I'm not sure if I'm posting this in the right forum.Anyway, I have 4 gigs installed,but don't think I can use all of it on my sytem.I have an HP Pavillion m8000n, and a GE force GTS 250 OC 512mb video card.It seems after trying to use the memory switch mod,that FSX works ok,but some aircraft on FS9 crash or do not work correctly.Mainly PMDG 747 and PSS 777.I would like to know what commands are correct for my system.The OS is Windows Vista Home premium 32 bit edition.Any help appreciated.Ron Ron Service .
March 19, 201016 yr You need to open an administrative command prompt (type CMD in the search box, right-click on "command prompt" at the top of the search box, select "run as administrator) and type the following: BCDEDIT /Set IncreaseUserVa 3072hit enter when done and close the window. Voila, your applications now have access to 3GB of address space rather than 2GB.

March 20, 201016 yr Did you do the modification of the fs9.exe executable to set the LARGEADDRESSAWARE flag? Without it, even with the /3GB switch set, FS9 is still limited to 2GB of address space. FSX SP2 and/or Acceleration has the flag already set in the executable's PE header.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO Bob Scott | President and CEO, AVSIM Inc ATP Gulfstream II-III-IV-V Sys1 (MSFS20+24/XPlane12+11): AMD 9800X3D, water 2x240mm, MSI MPG X670E Carbon, 64GB GSkill 6000/30, nVidia RTX4090FE Alienware AW3821DW 38" 21:9 GSync, 2x4TB Crucial T705 PCIe5 + 2x2TB Samsung 990 SSD, EVGA 1000P2 PSU, 12.9" iPad Pro Thrustmaster TCA Boeing Yoke, TCA Airbus Sidestick, Twin TCA Airbus Throttle quads, PFC Cirrus Pedals, Coolermaster HAF932 case Sys2 (P3Dv5/v4): i9-13900KS, water 2x360mm, ASUS Z790 Hero, 32GB GSkill 7800MHz CAS36, ASUS RTX4090 Samsung 55" JS8500 4K TV@60Hz, 3x 2TB WD SN850X 1x 4TB Crucial P3 M.2 NVME SSD, EVGA 1600T2 PSU Fiber link to Yamaha RX-V467 Home Theater Receiver, Polk/Klipsch 6" bookshelf speakers, Polk 12" subwoofer, 12.9" iPad Pro PFC yoke/throttle quad/pedals with custom Hall sensor retrofit, Thermaltake View 71 case, Stream Deck XL button box Sys3 (DCS/P3Dv4/ATS/ETS): AMD 7800X3D, MSI MPG X870E Carbon, Noctua NH-D15S, 64GB GSkill 6000/30, EVGA RTX3090 Alienware AW3420DW 34" 21:9 GSync, Corsair HX1000i PSU, 4TB Crucial T705 PCIe5 + 2TB Samsung 970Evo Plus, TM TCA Officer Pack, Saitek combat pedals, TM Warthog, TM RS300 FF wheel/pedals, Coolermaster HAF XB case
