I have a Dell Inspiron 3452 that has 2gb RAM. I bought a 4gb stick that was supposed to work on The Dell wedsite, but all I get is beeps when I try to turn it on. The RAM was the exact same speed and size, only difference was that it was 4gb instead if 2gb. I updated the bios but I dont know if it actually changed anything because it still didnt work. I asked the seller on amazon if it would work and he said it would. I seated the ram correctly, I know this. So why is the RAM not working.Help?
