    Hey guys,
    I got my RAM from Memorytogo.com
    I got 2GB worth of RAM.
    I tried installing them but it only reads them as 1GB off RAM.
    I installed both and they appear as 1GB. So I thought hmm one must not be working and tried to just install one ram. Didn't work out. The RAM didn't appear at all this time when I installed only one of them.
    I tried switching the RAMs around and also tried different PCI slots. If I don't put both of them in together, it doesn't read at all. When I put 2 RAMs together, it reads as 1GB.

    Is there an error in my RAM slots or you think they sent me just a gig worth of ram?

    Since you posted in the mac pro section i will assume you have a mac pro? If so it HAS to be installed in pairs so it sounds like your doing something wrong there. Now your certain they are 1gb chips not 512mb chips for a total of 1 gb? and your installing them on the same riser? and PCI slots? you shouldn't touch the PCI slots for this.
