DDR3 1333 memory.

Try using the Crucial tool at www.crucial.com.

It should identify it for you and then offer you what they have for 8g packages.

 

Crucial says:

DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.5V • 512Meg x 64

 

Could someone please confirm or advise differently to this? I called apple and the "Tech support" lady could not give me an answer to this, and also called crucial, but they dont have a definitive answer.

What I want to know is if the MBP 13" with the Sandy Bridge i5 2.4GHZ will accept 10666 memory of if the max it would take is 10600

I really want to order 8GB today but want to make sure what is the best memory I can get for it.

Thanks in advance!!

Confirmed. DDR3 memory with support for DDR3 PC3-10600 speeds.

 

That we all know thanks to Crucial, but what I wanted to know was if it would take PC3-10666 but reseraching online I found out its basically the same:

Thanks for the reply though!

 

someone linked to the 10666 model on newegg in this very forum. I am about to order, but don't know what to order now. I guess one could take out their ram and look...

 

I will be ordering this:

It does not matter which speed rating you use as long as it is DDR3-1333 or faster. Each company labels the PC3-106xx bandwidths differently.

 

Thank you! This is the answer I was looking for. I already ordered pc3-10600 rather than 10666 just to be safe

 

Do you guys think it would be ok if I put my old 8GB 1066Mhz (currently working with my 2010 MBP) in the new 2011 MBP? I know the bus is different...but I think it is backward compatible....just want to clarify! Because I think 1066 and 1333 only make a little difference, and I can't be bothered to buy a new kit of RAM when I upgrade!

 

I took out my 8GB 1066 Mhz from my 2009 MBP and installed it in my new 2011 MBP already. Some say it wouldn't work, but it's working fine and recognizes it in "About This Mac" and in iStat Pro. Pretty sure it's working great!

 

Can someone confirm if the new 15" comes with 2x2GB or 1x4GB modules? In other words, do I need to get 1 or 2 4GB module to upgrade to 8GB?

 

They come with two 2gb sticks
