So even guys with 24GB of memory FSX will only use 3.5GB or so. These are 32-bit limitations.WOW,eye opener......Computer GURU's confirm or deny this simation.....

that even though you are running FSX on a Windows 64bit system,you are truely running it as 32-bit program with 32-bit memory restrictions.

Actually, it is only 3Gb of address space that FSX gets allocated - if I understand the tech reading about it:
>> http://blogs.msdn.co...ress-space.aspx <<
But, a 64Bit OS has access to a much larger Virtual Address Space than a 32Bit OS does (I think [scratches head]). So that (sort-of) explains why, with a 64Bit OS you don't get the dreaded "OOM" errors. FSX still only uses 3Gb but can get allocated a contiguous section of mem space.
I was getting the "OOM" on my 32Bit Win7 using areas such as FTX Canberra. Switched to a 64Bit Win7 and no more "OOM"s ... (so far)
Did that help John?
