Hello Everyone again, I would like to upgrade my computer's memory from 256MB to 512MB. I would like to just add another stick of 256MB to the system, but I have not idea if the original RAM is ECC or not and I know that the both sticks of RAM must be the same. I would like to know if there is anyway I can find out the type of ECC in the original RAM. I cracked opened the computer and checked the RAM already, but that doesn't help, so is going into the BIOS either. Thanks :smileyhappy:
