Start-up failure after memory upgrading Tags: Memory DDR2 agps January 7, 2013 9:07:25 PM Hello, I have a couple of Dell Optiplex GX620 desktop pcs running WinXP. They only have 1GB ram installed in the form of 2 x 512MB DDR2 PC2-4200U. I tried to upgrade one of my PC units with the memory of the other one (also 2 x 512MB DDR2 PC2-4200U), so I would get a total of 2GB. After inserting the memory one the slots, the PC didn't start. What did I do wrong? Thank you in forehand agps More about : start failure memory upgrading Can't find your answer ? Ask !
