My Mac is
2.8 GHz Intel Core 2 Duo
Model Identifier: iMac7,1
It came with Apple factory 2GB RAM (2 x 1 GB modules)
I upgraded in 2007 using Crucial RAM to total of 4GB (2 x 2 GB modules)
4 GB 667 MHz DDR2 SDRAM
CL = 5
I had thought that was the maximum RAM that model iMac could accept.
Now I am reading that it can use 6 GB RAM! (1 x 4 GB module + 1 x 2 GB module)
I read this on multiple forums.
What does Crucial say about this?
I recently upgraded from Snow Leopard OS X 10.6.8 to Mavericks OS X 10.9.5 and my Mac runs much slower.
If I can upgrade to 6 GB, Can I leave one Crucial 2 GB module & just swap out one for a 4GB module? Does it matter which slot has the 4 & which has the 2?
Will I not be able to use dual channel memory since each module is different size?
Can you provide a link or part number for a 4 GB module?
