DDR3 PC3-8500

Memory Type: DDR3 PC3-8500, DDR3 (non-ECC)
Maximum Memory: 8GB
Slots: 2

Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

Memory or DRAM is the "working" memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis.

video - installing memory



Storage Drives -- hard drives and solid state drives -- are the permanent memory for the programs and documents on your computer.

Data Transfer Rate is the rate at which data can be sent or received. This is determined by your motherboard. A drive with a higher transfer rate will only run at the rate of the motherboard's transfer rate.

Cache is a type of working memory that allows the drive to perform faster.

RPM is the rotations per minute of a hard drive which effects the speed of data transfer.

Solid State Drives are non-moving memory, so access speed is instant.

Compatibility for Mac systems.
Engineered to be compatible with your Apple® system, Crucial Memory for Mac takes the guesswork out of a memory upgrade. Since Apple systems often have very specific memory requirements, including particular component densities, speeds, and SPD programming specifications, it's important to buy your memory from people who know Apple computers inside and out. With over a decade of experience manufacturing and developing memory for Apple systems, we make it easy to find memory that's been designed specifically for your system.

Reliability for Mac systems.
If you're an Apple computer user, you probably expect intuitive, reliable performance from your system. We think memory should work the same way, too. For each module we manufacture, we send it through a rigorous testing process to ensure that you're getting a reliable, high-performance memory solution. Every module that leaves our doors has been extensively tested at the component level for voltage and temperature resistances, signal integrity, and software compatibility. The result? Reliable memory that meets or exceeds Apple's own memory requirements. With the latest lead and halogen-free technology and built-in thermal sensors1 to help control your system's cooling, Crucial Memory for Mac features advanced innovations.

      One of the easiest things I've done. Took about 4 minutes to take out 10 screws, take out the old ram, replace with the new ram, put the screws back in, re-boot...done. My old, tired macbook pro is not so tired anymore!

              Upgraded my personal laptop for more serious editing on the run. Needed a boost as I needed to quit one app to open another and now I can flow seamlessly between apps. INstallion takes 5mns and the boost is noticeable right away.
