Ram is so cheap lately, I couldn't resist purchasing another 2GB of ram. Is it possible to set up FS9 & FSX so they can be both run optimally with 4GB's of ram? If so, could someone be so kind and reply.Thanks,Ken

The OS and FS are both pretty smart about how much RAM to use, and 4GB is plenty of playspace to share with even the biggest of memory hog background process, so there is nothing to tweak for this as such. BTW, if you are using anything other than a 64 bit OS, your OS will only see 3.25-3.5GB RAM due to the way 32 bit OSs handle memory.Gary

Are you running XP w/32 bit?If so, look below, or do a search for quality info on this subject (search recent posts for '4GB'). Regardless, you will still want to look at this issue if running VISTA.One of the important tweaks is via a program called 'Explorer Suite' which allows you to change the FSX.exe file to accept more than 2 GB of RAM (stock only uses 2 GB).I just installed 4 GB on XP 32 bit, XP can see 3.15 GB (my video RAM is showing 700+ MB in use with a 512 MB card via 'Mem Status'...another plus), and FSX is set-up to use more than 2GB. That along with a couple boot.ini switches and I am using about 1.5-1.7 GB of RAM 'in' FSX, with about 1.5-1.7 to spare. That is nice to see I tell'ya, as without some of these tweaks you may not be using your 4 GB of RAM to its fullest in FS.It has made a great difference on my machine. Don't expect frame rates to increase, but expect scenery to 'lock in' much quicker, which means many many less 'blurry' issues, and the sim just runs much smoother all around inside FS. As FSX is pretty darn smooth anyway, that is saying something.

Not positive Ken, as I don't use FS9 anymore. But it sure would not hurt to try to modify the .exe (back up your original) and the boot.ini changes will work for XP in general.As long as you back everything up which you change, I would definatly experiment ;)

I'll set aside some time next week and try it out.Ken
