Hello everyone. I have an emachines c6415 that is about 5 years old and Out of warranty. I been trying to install 2gb but need the bios update. So far it has amd athlon 64 processor 3400, 512 mb, 160gb hard drive, I wanted to install 2gb to play Lotro online, the game is wonderful but not for someone using 512 mb of ram. I try going to emachines but they want me to pay $129.99 for half hour. Also i did brought the 2gb memory from new egg. com and used their memory compatibility to make sure it was right for my comp. it was the 3 best match for my computer.
