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

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.

I have macbook 7.1 2.4ghz core 2 duo white unibody 2010 with 8gb ddr3 1066mhz from crucial and seagate momentus xt 500gb 4gb ssd 7200rpm.

System is fastest its ever been. Yes it works very well.

Hey guys

I want to this to mine, could anyone point me to the right ram from a UK shop?

many thanks

John

Hey John,

Try Crucial, it's only 39.99 for 8gb upgrade there but look under 13inch macbook pro 2.4ghz

regards,

Jeremy

I'm so relieved to see this after reading Apple's claim of 4GB Maximum. I have two 4GB DDR3 1066 chips waiting for me in an envelope at home and was worried I'd wasted my $60! Looking forward to making this MacBook mid-2010 run better. At the moment my 4 year old MacBook running Snow Leopard runs heaps better than this new one running Lion.

Thanks everyone.

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.

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.

I have run my macbook with 8gb for about a year but wouldn't advise it. It overheats a LOT and has led to hinge cracking (however Apple replace the screen for me)!

Samuel,

I normally don't feel a need to respond to other's posts, but, with all due respect, I have to question what I see as a misperception of things on your part.

I have run more than 6 of these MacBooks, model A1342, with 8GB ram and NONE have run "hot" at all, and all but one have had the cracking near the hinge points.

In my opinion, the cracks are related to physical stress, NOT heat.

You may very well have a MacBook that is overheating for other reasons than the RAM upgrade, and also has the cracks near the hinges, but I feel they are unrelated.

On the overheating issue, I would check that the fan and heatsink "radiator" are clean (blow the dust out with canned air). If that doesn't solve the heat problem, I would go in and remove the heatsink, and clean off the old thermal compound, and reapply GOOD QUALITY thermal compound and reinstall the heatsink.

If you wish, and are suspicious of the RAM upgrade, you could first try checking to see if removing the 8GB RAM upgrade and replacing it with the stock RAM sticks solves the overheat problem, but I doubt that it will.

As for the cracks - welcome to the club - nearly all these A1342 plastic unibody MacBooks have them.

Hello,

I just tried, and it works with 8G of ram.

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!

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

I will give it a try.

16GB for a 13 inch will ONLY work on the: Mid 2010, 2.4Ghz, 1067 MHz' ...

It has been tested and works perfectly

You can buy it here...
