Why only 512MB shown in 3870 X2?

[morganainana]

I have my HD 3870 x2 enabled but there is only 512MB shown and also my 3Dmark06 score is always around 7500, any one can help me?

Wait,do u have one single HD 3870X2 or 2 HD 3870s in SLI ?
If u have 2x HD 3870 512MBs in SLI,u still have 512MB memory because CrossFire doesnt double the memory

mine laptop is Alienware M17 and i choose 1G for my graphic card, and it says its a HD 3870X2, so no matter how, it should have 1G shown right?

ALIENWARE M17 has 2 HD 3870 512MB on it mate it will show 512MB, SLI/CF doesnt double the memory

Right click on desktop and go to Catalyst control center,information center,graphic hardware,in there check that u have a Primary adaptor and a linked adaptor to be sure that CrossFire is enabled.
Also download GPU-Z and check with that too.

Make sure u have the latest Catalyst driver installed too.
