Maximum RAM 2007 iMac

My Mac is

24” screen

2007 model

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 

Non ECC

CL = 5

200-pin

PC2-5300

 

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?

 

Regards,

 

Steve

Re: Maximum RAM 2007 iMac

Hi iconclast, Thank you for contacting us today. I pulled up your iMac in our system and it appears that we still recommend upgrading to 4GB with your system. We have not done any testing our end to guarantee compatibility with 6GB of memory in your system. This is something you could try and remove the RAM and return it if it doesn't work out. It would not hurt your system in any way. Please let us know if you have any other questions or concerns.
