Hi all, It's been a while but I finally have time to get back into focusing on my computer and Apple products. I just went to the local computer store and got 8GB Ram 1066mhz - Kingston KTA MB1066K2/8G Apple RAM and got it installed by them. However I just started up my computer, everything works. I checked the about my mac and it says 1333mhz. Do you know why this may be? And is this an issue? So far I haven't seen much improvement in speed to be honest. I am mainly looking at using Lightroom and exporting photos. etc.
