iMac 27" memory upgrade question

[bgbs]

I have a late 2009 27" iMac that uses 1067 MHz DDR3 memory. Can I install 1333 MHz memory modules instead? Or it will not work?

Here is the link to my Mac's specs http://support.apple.com/kb/SP576
Let me know
Thanks

1333 MHz modules will work, I even have two in my 2009 MBP, and they even get recognised as such.

That's interesting because this page http://support.apple.com/kb/HT3011
does not list that upgrade as an option. I guess I can give it a try and see if that works.
