[Trickster]

Well, I have a problem with my crossfire, I just reinstall XP because of several problems with Vista which is a problem with 3D mark 2006.
So, once installed, it start , but it tells me that I only have 512MB of RAM DDR4 while I have a HD 3870 CrossFire 512MB of RAM each ...

That is if you have any solutions ...

In addition to 3D Mark 06 says that I have the DirectX 9c when I directx 10 as you know, after installing the following CCC / drivers

have your drivers were searched ?
and for information:

This new variation of DirectX is based on a new WDDM driver model introduced in Windows Vista. It will, therefore, not available on earlier versions of Windows.

First download link : http://game.amd.com/us-en/drivers_catalyst.aspx

[Dr. V]

and you installed the drivers for XP on a vista?

[Trickster]

I followed the path indicate -> link here and then Windows XP Professional / Home -> Radeon -> Radeon HD 3870 Serie -> GO

but it is nowhere written that it is for vista!

Finally, I'm in XP, and I got to walk my crossfire, in fact, you have to restart the PC and then it crashes, and restart, start the crossfire and that is good lol, a rather odd ritual I know my allows me to double FPS in crysis anyway, to tell you, in BioShock (a game not very powerful anyway) bah I turn 60 everything thoroughly and in 1680 * 1050 while in crysis while high 1680 * 1050, I'm averaging 25 and 50 with the crossfire, but good overheating and multiple crashes due to incompatibility certainly face in games
