Intel Core 2 Duo 2.4 GHz processor (P8600 model) with 1333 MHz RAM

[exalted]

Hi everyone,

My 13-inch, Mid 2010 MacBook has an Intel Core 2 Duo 2.4 GHz processor (AFAIK P8600 model that is) with specs below:

* Processor Name: Intel Core 2 Duo
* Processor Speed: 2.4 GHz
* Number of Processors: 1
* Total Number of Cores: 2
* L2 Cache: 3 MB
* Memory: 2 GB
* Bus Speed: 1.07 GHz

Recently I discovered (although not officially supported by Apple) that I can upgrade my memory up to 16 GB on this MacBook model with a recent firmware, which I have already installed.

As per the specs this processor supports 1066 MHz, which is okay, but I am having some difficulties finding 8 GB of DDR3 1066 MHz items to purchase, instead 1333 MHz is already available in my local store.

My question for you is about FSB speed: do you know if could I just replace the current memory modules with 1333 MHz ones and those would simply run at a lower frequency (i.e., 1066 MHz) or wouldn't work at all?

Thanks in advance.

Cheers,

If you're in luck it will work but if it doesn't it will just step it back to 1066Mhz.

Thanks for your reply. Indeed the question would be: are you 100% sure that it would step back to 1066 MHz, or are you just guessing?

99.99% But I'm sure it will work.

Thanks for your reply! For some reason I couldn't load URL you shared, anyhow in macmemory.com I found this page instead which states a maximum of 8 GB of RAM which is not correct. According to everymac.com:

Apple officially supports a maximum of 4 GB of RAM, but third-parties have determined that it actually supports 8 GB of RAM running Mac OS X 10.6 "Snow Leopard" and 16 GB of RAM running OS X 10.7.5 "Lion" or higher and the latest EFI update.

Anyhow, I still am not sure if 1333 MHz would just run at 1066 MHz (which is fine for me) or it would simply not work?

Thanks.

Thanks. Let's hope so!

I wouldn't reccomend going for 1333 cause here is something I found.

I accidentily bought 8GB of 1333mhz RAM for my mid 2009 13" MacBook Pro (the name and number scheme is too closely related). It ran fine, but the shared video RAM was running at 1333mhz, and the system RAM was running at 1066, which I find difficult to understand how it did that. A friend that has the exact same MacBook Pro bought the same RAM several months earlier, only to have it die after 6 months of use. I ditched the RAM and went back to 1066mhz sticks. Using faster RAM will not make a noticable difference in these laptops. A quicker hard drive will make a greater difference.

Thanks for sharing. I don't think this is strictly related to my question though. I don't much like to struggle with different problems of other people, rather I would like to hear an opinion from someone who knows what he/she is talking about.

Also, suggestions such as "don't do that, instead do this", or "why don't you do that instead?" won't actually answer the question.

Cheers,

Here is 1066 RAM :

Only thing it's 8GB and not 16GB

If you want to really see extra performance buy a SSD.
And if you're done with this thread select answer so thay will see this problem is solved.

Thanks for your answer. I am interested in performance, everyone does, but SSD is not the issue here. As soon as I will have a fulfilling answer I will definitely pick it as "the solution".

But is your question still unanswered? Cause what I answered was It will work but it wont be safe cause on a thread I found on Apples site said that it worked for some time but then it crashed his computer so I wouldn't try it.

Hope this helped.

Thanks for your answer, but that is not the solution to my question. I don't think so. Cheers.
