Ram Modules For Mac

  • A memory upgrade is the fastest, easiest, and most affordable way to get more performance out of your Mac system. Standard DDR3 modules help Mac systems reach speeds up to 1600 MT/s, and DDR3L modules start at 1866 MT/s. Systems that support DDR4 memory technology, like the latest iMacs®, can get quicker responsiveness with faster speeds.
  • All you have to do is pop open the access panel, remove the existing RAM modules, add your new modules, and then replace the panel. The whole thing should take less than five minutes. And when you’ve installed the new RAM, your Mac should boot up as normal.

Often we have customers asking if they should install Apple memory as a matched pair or not. With the exception of Apple RAM for the Mac Pro Model IDs 1,1 and 2,1 and the Mac Pro 3,1, no other Mac requires memory to be installed in a matched pair.

Performance Improvement

When people talk about a 'matched pair' performing better, they are talking about very specific cases of two modules of the same size when compared to an individual module of the same size. For example, a pair of 2GB modules (4GB total memory) will perform better than a single 4GB module.

4GB Paired vs 6GB Non-Paired Configuration

In many cases, however, it is necessary to consider the difference between adding a single DIMM that increases your total memory versus having a matched pair. One common example is the iMac Model ID 7,1 or iMac 8,1. The maximum memory you can install in these machines by way of a matched pair is 4GB (2GBx2.) However, the actual maximum memory in this machine is 6GB, which is installed with a single 4GB and a single 2GB. While you will not have the benefit of the matched pair, your total memory at 6GB is higher, negating the boost you get from the matched pairing at 4GB. In most instances, you will gain more performance from a larger memory configuration than you will from a smaller, paired configuration.
