Upgrading a Mac...?

[sqrage]

My friend wants to upgrade his Mac Pro from 3gb. It currently has 3 1gb sticks.

Does that mean it only runs triple channel? If so why does the motherboard have 4 DIMMs?

Can the motherboard run 3 2gb sticks and 1 1gb stick for a total of 7gb?

God Macs are strange...

That's actually an Intel gimmick.

You can use regular memory with it.

Is it triple channel?

What model is it? The 2009 Nehalem? For best performance I'd keep it in 3's.

I believe the typical route is to throw it away and buy a new one.

in case anyone stumbles upon this in the future. the '10 model, as far as I could tell, has triple channel on the first 3 DIMMs and runs the last one single channel.
