Just installed two 2Gg modules in my wife's MacBook Pro. Installed in 5 minutes with no problem. Wow! what a difference the extra memory makes. I always buy my RAM from Edge. They have the best prices and great customer support.

Your Apple MacBook Pro uses PC3-8500 type memory.
Your Apple MacBook Pro can support up to 8GB of memory. For optimal performance install the maximum amount of memory in each socket.
Your system comes standard with 4GB of RAM. If you have upgraded your system then you may have a different amount.
A memory kit is comprised of 2 memory modules. For example, a 1GB memory kit has two 512MB memory modules. This is abbreviated as (2x512MB).
Yes. Your Apple MacBook Pro requires memory to be installed as a kit because it requires memory to be installed in pairs within a bank. To make it easier for you to install memory that will be compatible, the memory modules available for purchase above are sold in kits.
A bank is a group of memory sockets. A socket is where a memory module is inserted. A bank can have one or more sockets.
One or more of the sockets in your system is already filled with memory. When you upgrade your system, you can either add memory to one of the open sockets and/or remove memory from a filled socket and replace it with a higher capacity memory module.
Your Apple MacBook Pro 15.4-inch 2.66GHz (MC026LL/A Unibody) June 2009 has 2 banks of 1 socket each for a total of 2 memory sockets.
*We recommend you upgrade your computer to the latest BIOS revision prior to upgrading your memory.
Both memory sockets are filled.
ETC tests each RAM module to ensure compatiblity with your Apple system. The memory modules listed above are guaranteed to work in your Apple MacBook Pro 15.4-inch 2.66GHz (MC026LL/A Unibody) June 2009.

I have had the memory long enough to know there are no major problems with the install or manufacturing defects, but not long enough to make sure all my software is having any trouble with it. I have noticed that after waking my laptop from a sleep, the mouse moves erratically and with a small latency. It did not do that before... so I am wondering if that is a result of the memory upgrade.

No problems at all. Memory is perfect. Good packaging (protection) on shipping container. Would recommend to anyone looking for memory source.

There was an item that was back ordered and was running a few days behind so Edge Tech changed my shipping to 2 day at no additional cost!
Thanks for the great service. I have passed your website on to our IT department to use as a future vendor.

I am so happy I went with this upgrade. My computer is so much faster. Not to mention Edge Tech was more than 75% cheaper then going through apple.

I was sure if this would work with my Mac Book Pro because other website said the max was 6GB, but since Edge has the guarantee I went for it and now I can run my virtual machine without issue. Thanks Edge.

Either RAM works or it doesn't. These sticks work. As far as Edge Tech: Ordering was straightforward and the chips arrived sooner than expected. My only complaint is that the sticks arrived in plastic casing that was very challenging to remove (thought I would break the boards).

Memory works great and was less expensive than buying from Apple. Shipping time was actually faster than the 7 days quoted for free freight. Great service and price overall

The memory arrived quickly and the instructions were easy to follow. I purchased memory for both my iMac and MacBook Pro from Edge. I was very satisfied all around. Only one suggestion for users installing their own RAM: don't try to blow the dust off--use a small vacuum cleaner and be gentle.

Edge always delivers on-time or better with the very best memory deals possible. This was just perfect. Website could be more specific for installs, but that's niggling.

My IMac needed more than just the 4 of Ram it came with..but which one would fit my "late 2010 IMac"? So many to choose from and all seemed different...with the great website I was able to choose my upgrade with confidence. Installed it in a heartbeat and poof it worked. The only glitch was it came by way of the USPS and it took forever to get to me...but otherwise a postive and instructional sale....

I have the first generation unibody Macbook Pro. While the product page did not specifically say that it could handle 8gb I bought it anyway. It works great and my computer is running so much better with the extra RAM.

I was shopping around numerous online stores for the best ram for my macbook that I had purchased in January of 2010 and found Edge Tech to be one of the manufacturers of laptop ram. So I gave it a shot because they had a discount offer available. I received the ram in less than a week and after installing it, upgraded from 2 GB to 4 GB, WOW, my computer feels like it has nitrous installed! Awesome products and definitely recommend to my friends and I may purchase another set for my girlfriend's older macbook. Thanks Edge Tech!
Memory or RAM is a piece of hardware in your computer that holds software applications that you are working on. It serves as temporary working space between your computer’s hard drive and CPU.
Adding memory will improve your computer’s performance. Specifically, it will speed up opening new applications, running multiple applications at once, and switching between software applications (multi-tasking).
One task that additional memory speeds up is opening a new software application. Let’s take this as an example. When you open a new application on your computer, your computer’s CPU fetches the application from the hard drive and stores it in RAM memory. It stores it in RAM because RAM is very fast relative to the hard drive. When RAM gets full, and you open a new application then the CPU needs to kick out one of your open applications, put it back on the slow hard drive, fetch the new application from the hard drive, and place the new application in RAM. Basically, it swaps the applications.
This game of swapping wastes time. Ideally, your computer could have an infinite amount of RAM. Then your CPU would fetch an application once from the hard drive, save it into RAM, and never need to kick out another application. There is no such thing as infinite RAM, but you can max out the RAM on your computer by adding the maximum amount of memory to each socket.
To max out your RAM memory, add the maximum amount of memory to each memory socket. To find out how much RAM each socket can support, divide the system maximum RAM amount by the total number of sockets in your system.
For example, if your system maximum RAM is 2GB, and your system has 2 total sockets then the maximum amount each socket can support is 1GB. If one of the sockets is already filled then you can always remove the existing module and replace it with a higher capacity module.
No. The 1975 Magnusson-Moss Act prevents OEM manufacturers from disqualifying a warranty when 3rd party memory is used. For more details, please see the Magnuson-Moss Act.
Memory speed refers to the amount of time that memory (RAM) takes to put data into its memory or send it out. Your device’s memory will have an upper limit on the speed at which it can operate.
A memory kit is a number of memory modules sold as a unit or a kit. For example, a 1GB memory kit will contain two 512MB modules. This is written as (2x512MB).
