quick question...

Say one has 2x 128MB videocards in an SLI config. does the system load the same thing into the video card memory. or does it only load the "half" that the video card is supposed to render?


Let me state it another way... will 2 video cards with 128MB each behave like a card with 256MB?
 
I believe it spreads it evenly, but there would be a miniscule difference than a true 256MB card I'm sure.

I could be wrong, but I believe I read before that it works that way.
 
No if you have two 6600GTs with 128 each you wont get 256 mem total.
Same with two 6800Us with 256, you wont get 512.
 
raid 0 connects two drives to make it one correct?

raid 1 is identical drives to save data.

Raid 0 is stripe. Both drive carry exactly the same data.

Raid 0 is Stripping, each drive contains 1/2 the data
Raid 1 is Mirroring, each drive contains the same data.

SLI does not combine the video cards. You would still have two 128MB video cards, but each card is effectively doing 1/2 the work. It effectively splits the graphics load across both GPUS, but only for software that was written to take advantage of SLI.

Think of it as dual processor. If you have two processors, you're not doubling your CPU speed, you're just splitting the workload between 2 CPUs.
 
is there any way to dump the contents of the videocard RAM into a file so that I may compare them?
