all windows 32-bit versions (windows 7, XP, vista) i get 3.58gb of useable ram.. am i the only one experiencing this? this still happens after switching motherboards and other ram...
32bit will recognized up to 4gb of system memory.....
What happens is this..... your gpu memory is part of that total system memory, hence that is why you are only seeing 3.58gb of memory on any of those 32bit OS's. That missing amount of memory is due to your MSI 8800GTS 512mb memory taking up part of the total memory addressing...
Switch to 64bit OS and then you will be able to see all of your memory. If you have a total of 4gb of memory, you will see 4gb in My Computer properties. You will not see 4.5gb because the gpu memory is not shown/included in the display of total memory.
[edit to add]
Oh by the way.... if you are worrying about your 32-bit programs not working if you switch over to 64-bit OS..... ahh... no worries... I had the same concerns myself.. I made the switch and for "me", all the 32 bit programs that I use before the switch still works after the switch.
But one thing for sure though..... you need to find all the 64 bit drivers for your components if possible, especially video, motherboard, sound, lan, etc..... printers and peripherals not so much... they will still work with the original 32bit drivers.
