    I just purchased 8g ram (2x4g) 1066mhz for my iMac 2.93mhz 2010 model. In my haste to take advantage of a special, I didn't realize it was 1066mhz forgetting that my iMac currently has 1333mhz (2x2g) installed.

    My question is: Can I install the 1066mhz along with the 1333mhz without there being a conflict? Or should I just return the 1066mhz chips and get (2x4g) 1333mhz to keep all the modules the same?

    Also: If there is no problem with using both at the same time, will the difference in speed be a noticeable drop in performance compared to having all the modules at 1333mhz vs. 1066mhz? I am guessing the 1333mhz will drop down to 1066mhz, but I'm just guessing.

    you can try. Either it will work or it wont.

    You would be better off just returning it.

    It will work, but only at the lower speed (lowest common denominator.)
