How do I tell if my system is 32 bit or 64 bit?

How much RAM do you have running? If more than 3Gb then it is 64bit. Or just look in My Computer System Info link.

Right click my computer, properties, general tab.

I saw a similar question once somewhere else, and the answer was:

"if you were running 64bit, you would know it"

which i thought was pretty clever

Okay, so I have a 32 bit system. Is it upgradable to a 64 bit or is that a whole new system?

Yes, how do you change it? I have 4gb of ram.

Its almost a whole new system. By the way you have to re-install windows with the 64bit disc, ifs that wat you want to know. I only dunno if you have to buy or if it comes along with the 32 one, meaning that should have been tons of people who upgraded and wanted to change it.

assuming the processor and motherboard are 64bit you can install a 64bit OS however the primary advantage to 64bit is not in 'massive performance' increases because there is very little 64bit software on the market most use.. its in the ability to use more the 2GB AND in order for that to work you software must be >2GB aware through its exe file

FSX SP2 is >2GB aware

FS9 and FSX-SP1 are not and must be manually edited with special software to see and use more than 2GB


There are advanatges to a 64bit OS and I personally only use 64bit however the change is not going to make your computer run 2x faster
