we have DELL 6800 server with 20GB RAM in it. We like to expand it to 64 GB. I checked Redhat web site and it say max memory is "Architecture & system dependent". Does anyone know what is Max RAM Redhat CENTOS 4.3 (32 bits) support? Thanks. ___________________________________________________ 您的生活即時通 － 溝通、娛樂、生活、工作一次搞定！ http://messenger.yahoo.com.tw/
