There are many different memory modules for different computers. This was exactly the right product and fit and worked perfectly. Not cheap, but very reasonable.

i just install this memory upgrade in my 2009 Mac Pro dual processor Xeon 2.26 GHz Quad-Core ,, and it worked instantly. i run the memtest86 to make sure there’s no errors and pass it without any single problem,, one thing you will going to notice that it will run in 1066 MHz speed not the 1333 MHz, and that’s fine.. definitely recommended

After installing these, the indicator light over the power button on my Mac continuously blinked. Then I discovered, after rearranging them quite a few times, that I had installed each 95%. You must hear each one CLICK in position. If not, you will get the blinking indicator and think they are defective. It runs smoother and faster since the update.

Worked perfectly in my MacPro 5.1 I had to remove some other ram I had in my machine as it was not compatible. (watch out for the voltage of the Ram and if it registered)
