I have an early 2008 Mac Pro running OS X Lion. It currently has 8GB of memory which consists of 4 memory modules of 2GB each, 2 on each of the memory cards.
I really want to go to 32GB but likely will go to 16GB. I do a lot of virtualization using VMWare often running Windows and Linux partitions so I think the additional memory will help a lot.
I plan to purchase from OWC which is where the memory I currently have is from but I see two options.
One is to buy 4 more of the 2GB memory modules which would then fill all slots and total 16GB and the total cost would be $241.
Another option is to buy 2 of the 4GB modules. The cost would be slightly more at $275.
-Would there be any advantages to this?
-Does it cause any issues and am I better off using all 2GB modules for example so that they match?
-One reason I prefer this option is although it costs slightly more if I'm correct that would leave 2 slots open where I could later upgrade with another 2 4GB modules for 24GB total.
Another option is am I better off (performance and price wise) simply starting over, getting all new memory. I can pay $549 and get 16GB (4 4GB modules) I know I could keep the current 8GB for 24GB total but again I don't think I need that much but I guess my question is, if I go with the 4 4GB modules and then get rid of the current 4 2GB modules would I get more performance using 4GB instead of 2GB modules. Also, I know OWC buys memory but I am assuming my best bet is eBay and if so, would I save money by getting the 4GB modules (4 of them) and then selling my current memory on eBay?
Thanks for your help with the above questions.
