[QUOTE="JChance, post: 505199, member: 39342"] Ok, I got in my 1.25 G4 MDD tower today. I bought it "bare bones," and installed the hard disk, RAM, and OS X today. I booted up and everything seems to be working fine. However, I installed *four* 512 MB memory sticks for a total of 2 gigs. When I pull down the "About this Mac" menu, it says I only have 512MB of RAM. When I open up the system profiler, it only shows one of the memory sticks in the slot. Under the diagnostics tab, it tells me that I have 4 RAM slots. J21, J22, J23, and J20. Only J21 shows having a RAM stick. The others just say "failed." I tired moving the sticks around, thinking maybe three of them were bad. But again, only J21 seems to be showing up. Is there a trick to getting the computer to "see" all of the RAM I installed, or is something else wrong? I tried to do a search on here and couldn't quite find the answer I needed. So hopefully you guys can give a little insight to a total Apple "noob." Thanks for your patience! [/QUOTE]
