I would like to upgrade my RAM in both my mid-2010 iMac as well as my mid-2009 MBP 13" laptop. I figure that I'd buy a pair of 4GB sticks and would like to have the flexibility to put one in each or both in the iMac and then put the iMac RAM into the MBP (since the iMac came with 4 GB and the MBP came with 2 GB).

I know the iMac RAM spec is higher, but will it work fine in the MBP and just run at a lower clock speed without issues? Here's a couple I was looking at:

Thanks!
 
yes, it will clock down.

there is no reason to buy "Mac" RAM, unless you really like spending more than you need to.

I wouldn't spend more though (at least at Crucial...the price is the same for both).
 
I wound up ordering the Crucial RAM. Per their site, it says it will work in my 2010 iMac 3.06 i3. I plan to use it in my 2009 MBP 13 2.26. If I ever dump the laptop, I can up my iMac RAM.
