Is this only an issue when using Excel or have you noticed any other programs freezing? Is it the same when working with. Admittedly, we can't address the full 4GB due to the OS being 32bit, but found it easier to buy 2x2GB sticks as we only had 2 slots available on each board. But upgrading to our MoBo's max capacity of RAM to 4GB made a huge difference. I work at a mailing house and have to deal with very large databases, and 4 years ago when I first started there, having P4 machines with 512MB of RAM wasn't enough and drove me mad (we are still running XP Pro). If possible I'd add another GB to make a total of 2GB RAM. The thing to remember is, is that that is the min req for running Windows 7 x86 (32bit), however with the addition of software like Office 2007 and other programs as well being thrown into the equation, then adding more RAM would definitely help you in the overall speed at which programs may run.

1GB RAM is OK, but it's the minimum requirement, so more would help.Re: MS Excel 2007 - freezes when saving file
