Will this ram work with my iMac?

Im trying to find out if this ram will work with my iMac? My iMac is a late '09 i7.

No, it won't. That is desktop RAM, you need 204-pin DDR3 SODIMM. This should work

Just noticed that it was 240 pin RAM. I wanted to try out the 1333 RAM in my iMac. I have 8gb of 1066 currently, and I just wanted to see if there was much of a difference. Thanks for the help though.

If you mix 1066MHz and 1333MHz, all RAM will run at 1066MHz thus you would have to replace all your RAM with 1333MHz so they would actually run at that speed. Besides, I doubt you would notice the difference. Only handful of apps can take advantage of the extra memory bandwidth.

It is not recommended to buy RAM faster than your machine will handle. It won't make the machine run any faster (the Mac sets the memory bus speed, not the RAM module), and there may be compatibility issues with the RAM clocking down to the Mac's bus speed. 800 MHz SODIMMs are widely reported to be incompatible with Penryn Core2Duo Macs, which require 667 MHz memory.
