Can I use DDR3 1333 Ram in a Early 2009 iMac.
I have 8GB 1333 ram for a 2011 Macbook, 2011 MacMini and 2011 IMac.
My question is can I put this in an early 2009 iMac, i.e. will it run at 1066. I know I use to use PC-133 RAM in my old crt iMac that used PC-100 without any problems
I bought this RAM for a Company issued Macbook Pro. They wouldn't pay for it so when I quit, I put back in their 4GB and kept my 8GB. Now If I can't use it in my iMac I'll have to sell it on eBay.
