Mike_27 Posted October 31, 2005 Share Posted October 31, 2005 I noticed you have 2 very similar 512MB memory modules. The model numbers are VS512MB266 and CMSS512MB-266. Why does your website suggest using model number CMSS512MB-266 for the Dell Dimension 4400 PC. It seems as if both of these models are compatible with this Dell Dimension 4400 PC. The only difference I see here is the price listed on newegg.com (a difference of about $20). What is the exact difference between these 2 model numbers?
