Hi there, I'm trying to upgrade a Presario S6030ANs memory. As we have a Dell Optiplex SX280 that doesn't work, we're trying to use the RAM from that. However, I don't know whether it will work. Written on the RAM from the Optiplex is 512MB 1Rx8 RC2-3200U-333-12 HYMP564U64P8-E3 AA 0515. I don't know what's on the Presario as I'm not allowed to take that apart randomly, it has to be for an actual upgrade (I accidentally made the HD loose a bit and now my family's paranoid about me going near it). Thanks
