Well you wouldn't have quad memory channel support but I am not sure of the difference in speed that this would make.
5 GB's is What You Want to Have.
Basically the issue with the Mac Pro is you want to use 4 Dimms or 8 Dimms in order to get Quad-Channel mode.
You'll want to stay away from configurations that would use 2 Dimms or 6 Dimms.
This was found out from the Excellent DigLloyd Blog
They really should upgrade the Mac Pro to 2 x 1 GB for 2GB Standard, but that is for another topic.

By the way: The speed boost from quad channel is almost immeasurably small.
I have sources but it's pointless to site, just trust me: not worth sacrificing RAM over.
Therefore: Your original 5 gig idea using the 6 DIMMS will be, for all intents and purposes, faster than throwing away the two 512MB chips for a total of 4GB--since more RAM is going to be way more important than the immeasurably small speed boost from using 4 chips.

Hey Slughead,
Think he's going for Quad Channel using 4 DIMMS.
Crucial 2X2, which I assume meant 2, 2GB DIMM's.
Should he put the the 2GB Modules in Riser 1 or 2?
Will these have any effect on performance?
BTW, Great Upgrade Articles.

Put the 2x2gig on Riser 1 and the 2x512 on Riser 2
Easiest thing.. pull both memory cards... install the 2x2 on the empty card. then insert them both back into the opposite slot [so the new memory goes on top, the old on the bottom] ..... 5gig...
