Hi all

 

I have a question.  Is it possible to get XP to recognize more that 4GB of ram?  Or will I have to change my operating system?  If anyone can shed some light on this I would be very thankfull.

 

Thanks in advance..................John

 

Well man, I can recommend you Win 7 64 Bits for this situation, XP is not bad but if you want to use more RAM, well Win 7 x64 is the solution

No, it is not possible. If you have XP Professional you're capped at 4GB.  If you have XP Home edition then you're actually capped at 2GB.  If you have the Home edition then I strongly recommend just buying Windows 7 64-bit and upgrading because 2GB is just not realistic with today's add-ons.  

 

For XP Professional, if I remember correctly, allocates 2GB of RAM to applications and 2GB to the OS, so FSX likely has only 2GB of real RAM to work with.  If you're using a lot of add-ons you're probably going to run into more CTD's and OOM's than is typical of people using Windows 7 whether 32-bit or 64-bit.

There is an operating system for XP that was designed for server applications. It is XP 64bit. I do not know for certain, but I believe it recognizes more than 4GB of RAM. IF you research this one a little, you may be able to buy a copy online.

No, it is not possible. If you have XP Professional you're capped at 4GB. If you have XP Home edition then you're actually capped at 2GB.

 

Both the 32 bit Home and Pro versions of XP have the same 4GB limit. The 64 bit version had a 128GB limit.

You need a new 64bit OS for that. So you can't make your current XP 32bit doo that. Either XP, Vista, Win7 or Win8 in 64bit version would do, but I would recommend Win7 64bit.
