I have a Dell E510 that came preinstalled with 1GB of RAM. I just added\ntwo Kingston 512MB RAM chips, boosting the system total to 2GB. Everything\nseems fine. No error messages or glitches....yet. A quick question,\nthough. When I go into the System Setup, scroll down to Memory\nConfiguration, it says that the original two RAM chips are rank 1, and the\ntwo new ones I just added are rank 2. What is that all about?
