Do a search. There are screenshots on here of other people using Late 2009 iMacs using 1333 RAM. This thread doesn't require any new proof.Post a screen shot of where it is telling you that your RAM is running at 1333 in a 1066 logic board.
Yes. People are running 1600 memory in their 2011 minis. It gives about an extra 5% in geek bench.Does this mean that a faster clock speed ram would work in my 2011 imac?
Currently has 1333mhz ram.. will it support say, 1600mhz or even 1866mhz ram? Assuming i remove the lower clock speed ram before,
No. Original i5-750 or i7-860 from late 2009 and 2010 iMacs only support 1066 and 1333 MHz.So can I theoretically run 1866mhz in my original 1066mhz system?
