    Hello, I recently upgraded my iMac RAM from 1GB to 4GB

    I purchased this: http://www.crucial.com/uk/store/partspecs.aspx?imodule=CT2KIT25664AC667

    I took the 1GB RAM out and replaced with 2 x 2GB RAM

    Its showing as 4GB 333 MHz DDR2 SDRAM. Should it show as 667MHz?

    I just put the 1GB RAM I took out my computer into my Dad's iMac (Same as mine) and its showing as 667Mhz DDR2 SDRAM. His set up is now 2 x 1GB RAM

    Is my RAM faulty??
