    I've been waiting for my i5 for several weeks. At the beginning of this week, I was told it was in Ireland, so I went ahead and bought another 4GB of RAM from Crucial.

    Yesterday, I found out that it hadn't even been built yet and I have at least another 2 weeks to wait. The silver lining is that I could upgrade to the i7 which for £160 seemed worth it.

    Anyway, my question is this: will the 4GB I bought from Crucial for my i5 work in the i7? I would assume it would, and the specs look the same. The only concern is that Crucial use different part numbers for the i5-compatible RAM (CT1115260) to the i7-compatible RAM (CT1115264). They are both listed as:

    DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.5V • 256Meg x 64 •

    It'd be good to know as the i5 RAM is still unopened so easier to return.

    BTW, the price of the 4GB kit has gone up from £58.99 when I ordered at the start of the week to £67.99 (both ex VAT), a significant %age increase.

    I can't speak for part numbers but aside from the CPU in the socket the i5 and i7 iMacs are identical so you shouldn't have any problems.
