Hi, I am able to buy some of these Ram modules for a fair price. I have tried to find the info on this forum but cannot find it and want to be completely sure since it is quite some investment. What do you guys think, will this work in my machine which is a 2009 Mac Pro 4.1, 8-core, 2.26ghz?

Thanks for your help!
