16gb in mid 2010 7.1 macbook pro

The Mid 2010 MacBook Pro needs 1066 MHz DDR3 memory, not 1600 MHz memory. If you install 1600 MHz memory, your MacBook Pro may not start up.

To buy the correct memory for your MacBook, visit OWC or Crucial > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

I ordered 16GB from this german seller:

http://www.ebay.com/itm/350836839038

Shipping was quick and the 16GB works perfectly in my Macbook Pro 13" Core Duo 7.1 2010 model.

I also have a mid-2010 Macbook Pro 7,1 with 4GB of RAM running OSX Mavericks.

I bought two sticks of 8GB DDR3 PC3-8500 SODIMM 1066MHz RAM.

When I install them both, the laptop doesn't boot. (stays at the grey screen).

I tried installing each individually with a 2GB stick, and the computer boots and runs for a couple hours but ultimately fails.

Do you think this is a Mavericks firmware upgrade problem? Has anyone tried upgrading RAM after they updated to 10.9?

allisonb213, can you post the brand of the memory that didn't work?

sorry to tell you, but this model can only be upgraded to 8gb RAM. of 1067 MHz DDR3

It has been tested with 16 GB.

allisonb213, any more news from your RAM upgrade and why it didn't work?

It seems like 2 sticks of 8GB would work, and thanks babowa for the above link. 16GB has been tested.

Can anyone suggest the correct supplier of these 2 x 8GB in the UK? Crucial? Or should I go with the German ebay supplier that gunnar-mobimatio posted above?

Well, you see, here is the potential problem: OWC has tested it to work with 16 GB with the RAM they offer; other suppliers may/would not have the exact same RAM and so may not offer it or won't guarantee it since Apple's official statement is 8 GB.

This is my very personal opinion: I would only go above Apple's recommendation if I then bought it from the place that tested it and guaranteed it to work. Not sure that I would trust a different source.

Additionally, no matter how much RAM you put in: keep the original RAM modules; if there is a problem with the machine and you need to take it in to Apple, put back the original RAM. That is what Apple told me as they want to test it with original equipment plus you'll have the modules to test the RAM in case there is a problem with those.

The 16GB I bought from a german Ebay seller worked fine. They claimed that it would work specifically in the 2010 7.1 model. I still use that Macbook daily. It´s these modules:

In my case RAM usage seldom exceed some 8GB anyway so my extra 8GB was mostly to experience how it would work.

If you insist to run a virtual machine to for example run another operating system in addition to OSX the 16GB will be a benefit.

But any 4GB user just upgrading to 8GB will realize the 2010 model may not need a replacement any time soon.

That's good to hear!

Thanks to you both. I'm going to bite the bullet and order it from this German eBay seller then.

Time to give this 2010 13" MacBook Pro a new life. I'm still on the original 2x2GB RAM that came with it.

I'm starting to do some web design, and can see running Photoshop, iPhoto, a web design app (Flux 4), and lots of Safari tabs and windows opened simultaneously would be difficult.

I took a look now at the current RAM usage and with Mavericks the previous mostly unused 8Gb of my 16Gb total has now been put to good use by Mavericks as File Cache area. So the 16GB is useful. I read this is a good sign that OSX has sensed that this RAM portion is little used and will allocate it for caching purposes.

I bought 2 generic 8GB modules from another eBay seller and it did not work with my Macbook white mid-2010. It boots and works for a few minutes, then reboots. Could be defective modules, I'm not sure.

Macs are quite finicky about their RAM; the only places I would recommend are vendors which specialize in Mac RAM and offer a lifetime warranty: OWC (macsales.com) or Crucial. Return yours (if possible) and buy from one of the above vendors.

From how I understand it the 16GB Ram possibility is with the 2010 Macbook Pro Core 2 Duo, the so called 7.1 model.
