hi there.
i just got a Mac Pro Quad-Core Intel Xeon dual 2.8 GHz with 2GB of memory.

i found an 8GB ( 2 x 4GB ) DDR2 PC2-5300 ECC Fully Buffered Memory Kit for
Apple Mac Pro Quad & 8-Core online for about $700

i've also found DDR2 PC2-6400 for about $50 more.

how can i be sure i'm buying the right memory for my computer.
they seem to be very model-specific.

do these prices sound reasonable?
i'd rather buy the 4GB chips to have more room to expand in the future.

i appreciate your help.

The System Profiler utility will tell you whats already inside your mac so at least you can compare the memory types.

The Crucial Website has a system profiler that will guarantee to find compatible ram

You need the PC6400 RAM. The PC5300 is for the older Mac Pros. Try macsales.com. I suspect their prices are much more reasonable and they clearly state which speed is for which model.

Per mrplow, the Crucial Web Site has a "Memory Advisor" that will lead you to the right memory. In this case, you want the Mac Pro, Xeon 5400 4 core type, which leads you to this page. From this you can see that what you want is DDR2-6400.

I have the same generation of Mac Pro and bought memory upgrades from Crucial. They work great, so I can confirm that this is the right memory for the machine.

My Macs: iMac 27" 3.4 GHz, Mac Pro 3.2 GHz, PowerMac G5 Quad 2.5 GHz, G4 Cube with 1.2 GHz Upgrade
My iStuff: 64GB iPhone 5, 64GB iPad4, 30GB iPod Video, 16GB iPod Touch
My OS': Mac OS X Lion, Mac OS X Snow Leopard, Mac OS X Tiger, Mac OS 9.2.2, openSUSE 10.3
