What is the maximum RAM for a MacBook Unibody A1342?

Apple says 4GB is the maximum RAM for a MacBook Unibody Model A1342. Has anybody tried installing 8GB in it? I'm hoping the motherboard is similar enough to the 13" MacBook Pro to support 8GB.

Thanks!

Install only 1066MHz, i tried 1333MHz is NOT working in my macbook white unibody and the system crash !!!

Can I install 1333 ddr3 ram on the macbook?

thanks

by

thanks I bought a pack 4Gb (2x2Gb) corsair 1333MHz, in an ebay offer

http://www.amazon.com/Corsair-DDR3-Lapto...

http://cgi.ebay.com/ws/130419714457

but when I install it, the notebook don't start and have a beep sound

I tried all the combinations (with the modules)

now I'm using 3gb in the notebook one original of the mb, and the other of this the corsair

now are running at 1066MHz

by

I don't think the 1333mhz ram is compatible with the 2010 unibody.

I have 1067mhz DDR3 ram and it works great.

I have 12GB ram and have run 16 GB ram in it until I pulled it

and used it in a desktop that I needed for multiple processing Apps.

No problems at all running this type Ram. I have tried the 1333mhz DDR3

as well because I had that ram in my 2012 quad i7 Mac Mini, but it is

not backward compatible to 1067mhz at least in my 2010 Macbook.

Hope this helps

I just installed 2 rams, 1gb DDR3 and 4gb DDR3 (5 gb total)... working smooth...

With 2 slots of 4gb DDR3 (8gb total), the system dsnt start

Cheers!

The MacBook (Mid-2010) has the same chipset as the 13" MacBook Pro (2010), so it too can support 8GB of RAM. Apple only says that you can expand up the 4GB, but you can install more than that. When expanding the memory always use this type: DDR3 @ 1066 MHz. Installing DDR3 1333 may work, but the chipset will run it at 1066 because of the frontside bus. Just to be safe, use the memory I specified.

by

+ @markus great answer. @Jon What you say about the 1333MHz is not really true that the FSB/chipset will determine the RAM speed. On many modern laptops/computers the RAM has it's own crystal to determine RAM frequency/speed. Apple incorporates a separate RAM bus using it's own crystal/oscillator on many of it's boards since moving to Intel.

by

2010 Macbook can actually support 16GB RAM. I know I'm running it right now. And the brand of chip may be either defective or incompatible. 1333mhz should be backward compatible for 1066mhz. Crucial is excellent and Mac friendly. That's what I use.

by

Hello Lyn, I have a mid-2010 Macbook Pro in the aluminium body. What you say about the 16GB - is that really possible as everywhere I ready says 8GB? My RAM is struggling at 4GB with normal functions and it is completely slowed by the use of time capsule.

not that i know of. Well you can, the memory "should" work, but the clock rate "speed" the RAM runs is being determined by the motherboard not the memory. The BIOS on the motherboard for a mac won't allow for overclocking etc. So even if you put in RAM that is rated for a higher speed, it will still run at the default speed it is designed to run. Assuming of course this is a brand that will work with mac etc.........

1333MHz RAM is more expensive anyway and I am not sure what kind of "real world performance gain" would be achieved depending on what your doing.

and I don't know what you will be using the laptop for, they are other things to make it faster if that is your goal. You might just need more memory? (your questions doesn't say how much you have now) just offering my opinion even thou I was not asked.

Buying Mushkin brand online at a place like newegg best price i have found recently with good reviews. (WAY cheaper then in any computer store, at least when i checked last week)

I have 8GB installed in my A1342, and it works great. Apple specs say it can accept up to 4GB, nut in real world it will run 8gb. Mine was purchased from NewEgg - this item - 1 x PNY Optima 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1066 (PC3 8500) Laptop Memory Model MN8192KD3-1066 - no problems at all (your mileage may vary)

Hello,

I just upgraded my macbook 7.1 (mid 2010) with 2x Kingston 4GB SODIMM KVR1066D3S7/4G, rated 1066MHZ. It works extra well. Each memory card cost about 30$ ( in Romania) so at about 60$ it's a must have upgrade specially when you upgrade from 2GB.

Best regards,

Paul

Yes you can :)

Just installed Silicon Power 4Gb RAM clocked at 1333MHz on my MacBook late 2009 model and it works just fine.

To note that since it was the last RAM module available @ the reseller, I've installed both a 4Gb RAM (1333MHz) and the OEM 1Gb Ram (1066MHz) and my system is working without any issue.

looking @ the system info you'll notice that the clock speed of the Ram is 1066MHz. IMO the 1333MHz has been down-clocked to 1066MHz by the system.

I've already planned to get another 4Gb Ram to get the MacBook to a total of 8Gb of RAM.

The MacBook needs to be "tricked" into using 1333MHz ram. YOu need to have at least on stick of 1066MHz and then the other can be 1333, otherwise the Macbook won't start.

You should always use the correct type and speed of memory specified by Apple. Always use DDR3 rated at 1066 MHz. On MacBooks (mid 2010), the bus speed is 1066 MHz. Using 1333 won't work, as you found. It's not

supported by the motherboard. To be safe and to prevent problems, ALWAYS use the memory specified by Apple. It will save you the headaches down the road.

Hi,

most of the technical details you mentioned I'm unaware of... for instance I too have a mid 2009 MacBook (2.26GHz) and got the 4Gb Ram module clocked @ 1333MHz and 1Gb Ram Module clocked @ 1066MHz.

Already tested up to 8 Gb Ram on my Macbook and it worked just fine.

This seemed to change. I'm on 8GB RAM in my macbook pro 13', mid-2010. This is the one with core2duo, but DDR3 Ram. There is a lively discussion in an apple forum that it can support 16gb (2x8GB) DDR3 now, due to a recent EFI firmware update. Actually all the core i5 models around that time (2010 15'' and 2011 laptops) are having problems with 16GB, thereas the 2010 core2duo models seem to run solid with 16gb ram.

Yay!

Apple forum:

OWC certified its 16gb moduls for these 2010 mac owners:

I will give it a try.

Hey there,

Maybe it's a little late, but I just want to tell everybody that 8 Gigs of ram works very fine in a white Macbook unibody 2010.

I still work on this Macbook because it's still super quick with this configuration.

I did the same thing on my iMac from 2007 (but than with 4 Gigs because the chipset doesn't work with more ram).

I have to say that the iMac and Macbook are build from a superb quality and still works as good as in the beginning, only with a little upgrade that doesn't costs that much.

I have also an other question for you guys: what about upgrading from an HDD to an SSD (in the iMac and Macbook)?

Kind regards,

Xavier

I added a 250 gig ssd to my 2008 macbook pro with 6 gigs of ram and it flies! not like my 2012 Retina but its quick!

by

A SSD gives you a very noticeable speed bump! Highly recommended though it really depends on how long you like to keep woking on a laptop that soon has 6 years on its belt ;) However, my 2010 Macbook with 2x8GB=16gb RAM + 512GB SSD is still rocking! Never had such a durable laptop before, I use it nearly every day. Even replaced the battery now so it is back to 4-5 hours on battery.

But I will probably upgrade soon to the next generation of Macbooks (2016), when they come out. Kinda sad that you can't easily replace the SSD on the newer ones though.

Hey guys,

I put an 8 gig 1600mhz kingston stick and a 2 gig pc3 that came with my friends 2010 White macbook for total 10 gigs of ram!

I was surprised it worked!

Cheers!

The ram has to be pc3 ddr sodimm with a maximum of 1066mhz. From what I'm seeing though, if it has 1066 mhz you can also install 4gb on each row. I just upgraded my customer's computer from 2gb to 4gb but the ram was the 1066mhz speed. It looks like jotastrong, you're trying to install too fast of a mhz for that computer most likely.
