They seem to show between 3.25 and 3.4 gigs in the system control panel. All servers were setup and OS installed with RAM already installed. We have been buying Kingston, rather than HP branded RAM. ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~ ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
