STUPID QUESTION about Vram :P

[RushFX]

Hi i have 2x 560ti

does 2gb + 2gb =- 4gb when doing SLI?

i only ask because i thought that it didnt but when i look at this

it says 4gb

You have 4gb correct, but in sli the data loaded in the VRAM is the same on both cards iirc. Hence why ppl consider it as having only 2gb of usable memory.

2GB usable.

Indeed. Adding it up is cheating

So basically ATI should have gotten a slap on the wrist for selling the 5970 as a 2gb card. I mean sure, it *has* 2gb on it, but you can only use half in CrossfireX.

IIRC both cards need to load the same textures, kind of like mirrored, and that's why the memory doesn't all add up into one amount.

damn got my hopes up for nothing

You don't even need hopes lol. 2gb should be enough at 1080p for the majority of unmodded games for some time to come!

Wait, what?

It's been the case with all cards (AMD/ATI/Nvidia) since I remember, the card physically has 2GB memory so that's what they market it as.

Do you think GeForce GTX 590 is any different in that regards?
