I would like to get 4 more gigs of ram for my 2008 mac pro. I don't want to spend the money on apple ram so I have a few questions about 3rd party ram. 1) is third party ram safe to use? 2) are there any downsides to third party ram? 3) wheres the best place to get third party ram? 4) whats the best third party ram brand? I have 4 gig in my 2008 Mac pro currently. (All apple ram) So I want to get 4 more 1 gig sticks. Will third party ram conflict with my apple brand ram? Thanks. I plan on using the money I save by buying third party ram to buy an ATI 4870 and a 1TB hard drive.
