I have a Dell Deminsion 2400 with 512MG RAM. I have been thinking about upgrading to 1G. I recently received an email coupon from Dell for 25% off memory so I bought some. It just showed up.;a I have also researched the net and found many good sites with detailed instructions on how to perform this. My question is how do it go? Was it worth it? I use this PC for business and it is 2 years old. Thanks for your response.
