Well...I'll be.......I had 3 gigs of RAM, but was NOT USING IT!.....

[Guest Nick_N]

It does not surprise me you results are better even without the >2GB marker in FSX. FSX/XP/Vista really need 3GB to do the job right. 2GB is the absolute minimum and with Vista 3-4GB is needed even more

C'mon guys, what about Windows XP SP3? Anyone have definitive info? I've been told SP3 overcomes the RAM limit without needing further tweaks but I'd prefer something more concrete than hearsay. All I know for sure is that the boot.ini tweak does nothing for my system using XP SP3.Cheers,Noel.

One more time... this switch has nothing to do with how much physical RAM Windows can use.It simply allows an application that can use it, to use more than 2 GB of virtual address space, taking that address space away from the Operating System.

[Bert Pieke 7,584]

You are right, this is confusing...The initial statement, that the /3GB switch allows someone to "use 3 gigs of RAM" is simply incorrect.If you search for the original thread, you'll find that the limitation that is overcome with this switch, is the amount of virtual address space that is made available to an application. This process is INDEPENDENT of the actual amount of physical RAM on the computer.

XP SP3 doe not do anything to the PAE systemIt requires the same boot.ini editsJust because you are addressing >2GB of memory does not mean FSX will change or run better. That all comes down to the system and how well you have tuned it and FSXMitch has followed my instructions for XP tuning and because of that, when he makes changes he sees results. Most systems are not set up for heavy load graphics applications and FSX is the king of them all. When you set up Windows correctly and properly defrag the hard drive (and I dont mean with the Windows defrag or even other typical payware defrag software) FSX runs much better and changes made which upgrade things further typically display results.

I run XP32 and FSX SP1 and I tried the 3 gig switch a while back and also edited the FSX.exe. On my system I got a lot stuttering with it turned on so I had to deleted it.

... I can't believe this thread... Bill L. - don't you just feel like you've wasted your breath on your long and detailed post three weeks ago? I sure do. This topic has been SO done to death on AVSim and the CoolSky forum. Doesn't anybody read? Or search? :-roll

[Guest shnala]

Well, I did just as you (Sesquashtoo) say. I edit manually boot.ini file. That also include visit to hardware store and buy that extra 1G of RAM! Windows recognize it... OK, cool. Plus I did just as Nick say - edit FSX.exe ! Then - some testing, of course..... :) And only jump I'm about to see...... is my own, from my balcony !:-bat (I live on 1st floor, don't look for some spectacle!) So,...did I done anything wrong ? Am I miss something ? My PC spec : AMD 2core 5200+, nVidia 8600 GT, 3G:-badteeth of RAM. regards, shnala ____________________________________ edit: I forgot to say : 1) Now I got multiple (3) boot start options (when turn on my PC, now I must sit and wait to choose on of the 3! boot start options !!! How can I eliminate this !?? 2) I notice (maybe it's just me, though!?) that on every switch between full screen & windowed mode my FSX freeze !? That option used to work just fine every time.... x(

Will it benefit FS9?RH

[Guest ledzzepplin]

Maybe I'm not looking at the right place but all I'm seeing on (C:) is "boot Configuration Settings" file. Is this the one? I've done several searches and still can't find a "boot.ini". Thanks!

[Guest ledzzepplin]

Hi Bill,XP/SP2 and I can see hidden files and folders but no boot.iniWonder why a search won't even find it?
