Hi all - I'm trying to help out a friend here - he has a stock Early 2008 Mac Pro (Dual Quad-Core Xeon, 2.8 GHz) with stock 2GB RAM (1+1 GB). We just installed an additional 8 GB (4+4) from Newegg.com, and the problem is that the Mac Pro system profiler now recognizes only the new RAM but not the old RAM; System Profiler states that the Mac has 8 GB (it's supposed to state 10 GB). We used a chart from Apple's website to make sure the sticks are installed properly in the right slots. Any ideas about why the Mac isn't recognizing the original two sticks anymore? I appreciate it - thanks !
Got a tip for us?

re-seat the RAM, that usually fixes the issue.
I just had to do that the other day; 12GB installed only showed up as 6 after a hard shudown. I re-seated it and now it's all there.
check the lights on the riser cards, the red lights tell you which DIMMs are affected

A lot of companies who sell 4GB and 8GB RAM modules for the Mac Pro state that all RAM should be of the exact same matching pair, as in only 4 GB modules from the same people, or only 8GB modules from the same people. So basically what they are saying is not to mix those modules with the lower modules.
Yeah - he was actually worried that this might be a problem before ordering the RAM, but I told him not to worry about it 😱 Either way, thanks for the suggestion.
Thanks - will try that as well in the morning.
I'm sure that's in the cards as well at some point down the road as Aperture use cranks up 🙂
