Adding more than 4 ram modules, Mac Pro

[seek3r]

Hey guys, quick question here.
I know that theoretically adding more ram modules than the current 4 that are in my Mac Pro may actually cause a slowdown, no additional bandwidth being added at that point (unlike the speed *jump* from 2 --> 4). I was wondering if anyone have gone from 4 modules to more than 4, and if so, what's the real world slowdown, if any, they've noticed?

Just curious, but if you are realitivly certan that there will be a slowdown, why would you "upgrade," even if the slowdown was small?

Because I need more ram, specifically I need ~2 more gigs to handle a couple more DB virtual machines, I *might be able to get by with 1 more, but 2GB is safer (my databases aren't that big). I have 3GB in there now (2x1GB upper, 2x512MB lower). I can either add 4GB and remove the 2x512 for the same number of modules, 6GB of ram, and itll cost me ~370 or I can add 2GB without removing anything for 2 more modules, 5GB of ram, and it'll cost me ~170. So if the slowdown isn't that big a deal I can save $200.

It's not that big a slowdown. But, if you can afford to dump what you have now and buy 8GB (4x2GB), then the slowdown will be nil. The slowdown comes as a result of the number of slots filled not the amount of memory installed.
