      For the Mac tower it is necessary to order this kit of RAM with the additional heatsinks. We installed these two sticks alongside 2x1GB sticks from Apple and an additional 2x1GB sticks installed when we bought the machine.Using the machine for motion graphics (After Effects, Motion) and editing (Final Cut) we ran out of RAM regularly and crippled our system by having to write to the hard drive cache. Slow and unresponsive was the result.With the item above in place we have rejuvenated this workstation and are happy with our purchase. [...]. Excellent product at a comparable price anywhere.

      I purchased this ram for my Mac Pro two years ago, and am now reading ECC errors. I would have expected the ram to last the lifetime of the computer. At least I got a couple good years out of them.

            You can never really have enough RAM right? This was the easiest upgrade for my system. Affordable, quick purchase, quick delivery, easy installation and worked right away. The hardest thing was getting it out of the packaging. Just be sure to reference the manual from Apple as to which slots to use when installing memory.

                This extra RAM made my MacPro Early 2008 faster and more responsive with Lion, and of course, with my workflow, which sometimes, 20 GB in RAM isn't enough due the file, sometimes, due the amount of processed files if working on batches, but to work with multiple opened apps 16 GB is enough (for Lion).

                  I use my Mac Pro 3.1 Quad-Core Intel Xeon, 2.8GHz to process and retouch photos, for graphic designs, desktop publishing softwares, 3d visualizations and some times video editing. Most of the time I work with many applications at the same time. I used to have 2 GB of ram and the computer struggles when 2 or 3 applications were opened. I updated my system to 8GB of ram (4GB+4GB). For some reason the previous 2 GB (1GB + 1GB) didn't work with the new one, but after taking away the old ram and placing the new one the computer recognize the 8GB with no problem at all. So far so good. Now I can run all the applications at the same time and it works great. Because my system accept up to 32 GB of ram I'm planning on buying more ram in the future. I rated 4 stars because I was expecting to use the old ram and I had to take them out. Beside that I's a great product.

                        B&H did a great job packaging everything. Very well padded and protected.

                          This is for a 2008 Mac Pro.
                          Spent quite a while looking around online for the least expensive option for this type of product. There seem to be a lot of really cheap bad alternatives with really bad reviews. I went ahead and bought this and it works. If you're looking to upgrade an older Mac Pro (i.e. you need this style RAM), save yourself the trouble and just get this pair. Just make sure you install them in the proper order (fill the top card, then the bottom).

                                    Works great in a Mac Pro, good for spreading the load on high-powered applications such as those for video editing and compositing.

                                      - Stopped some data back up problems that I was experiencing.
                                      - Easy to install.
                                      - Crucial has a neat program that you download to your computer and it tells you the exact kind of memory you need.

                                        Is your computer running slowly? Does LR or Photoshop take forever to execute commands, to render previews?

                                        Well, RAM is the best investment you can make. Easy to install. B&H has by far the BEST price on this item anywhere.

                                        I'm now running 10 gb RAM, and will probably buy another 8gb now that 64 bit can take advantage of it.

                                          I bought this a year ago for my new mac and again a week ago to upgrade it further. Both times I just plugged it in and was ready to roll.

                                            For the Mac tower it is necessary to order this kit of RAM with the additional heatsinks. We installed these two sticks alongside 2x1GB sticks from Apple and an additional 2x1GB sticks installed when we bought the machine.Using the machine for motion graphics (After Effects, Motion) and editing (Final Cut) we ran out of RAM regularly and crippled our system by having to write to the hard drive cache. Slow and unresponsive was the result.With the item above in place we have rejuvenated this workstation and are happy with our purchase. [...]. Excellent product at a comparable price anywhere.
