    I got a refurbished m1530 from the outlet and it has issues with its power button so it will probably be going back but I noticed something while I was looking at CPU-Z. The memory is at 333 MHz. Now I don't know much of anything about ram but I know it said the ram was at 667 MHz.

    It shows PC2-5300 (333 MHz) for both ram cards and my order says

    -- 4 GB DDR2 SDRAM 667MHz (2 DIMMs)

    Am I just stupid and that 667 means combined?

    DDR in DDR and DDR2 stands for Dual Data Rate. Meaning the effective speed is twice what that clock reads. 333x2 = 666, but with some marketing, it equals 667.

    Ah thanks. I just thought it was weird that I heard 667 MHz everywhere I went and when I noticed that in cpu-z i figured there had to be a reason and if there wasn't then I wanted to point it out to dell when they fix my power button.
