Solved question about vram

[mpcrsc562]

i was already here, so i decided to ask this question, plus i'm too lazy and strapped for time (right now) to google for the answer :huh:

anyway, i have two 512 mb hd 4870 in crossfire config and my question is this: is my vram added together in series (512mb+512mb=1gb) or do each of the cards use their own 512mb?

just wanted to know.

512 MB each, it doesn't get added together,

Do SLI or CrossFire double the memory ?
This is one the questions that many people make mistake understanding it .
The answer is NO , SLI or CrossFire doesnt double the memory , You have a 512MB card , adding another card wont make your memory 1GB, it still will be 512MB
Another example :
A game needs 512MB card to run at maximum settings , and you have a 256MB card , and you think if you add another 256MB card , your memory will be 512MB and thats not true.
