You need at least 1 bridge and

Check that box. Enjoy bud!

PS: You may find a few games that do not support crossfire as well as you would like. I suggest setting up profiles for those games that disable crossfire on the fly.

[Gallatin]

thank you, you are real helpful. if i connect both of the cables should be a problem? what profiles?

[JrRacinFan]

If you connect both cables it will just allow a higher res to be played. I beleive anything above 19xx x 10xx.

Profiles right here:

Make sure you backup your current settings:

Then you can go back and disable CrossfireX. Save it as a profile called "Cfire Disabled". :)

If you do it correctly you can right click the ATi tray icon and be prompted with this:

tnx man.

here one screen everything seems ok. i have same gain in 3d06 +2.000 marks:rockout: on stock speeds.

but is seems to be a problem. i don't know.... i first 3650 the bus interface is x16 on pci-x in second 3650 is x2. is that normal?

[JrRacinFan]

What board is that on man?

[Gallatin]

ASUS P5B-Premium vista edition. the chipset is P965

[Gallatin]

i just read from asus website

2 x PCI-E x16 (blue @ x16 mode, black @ x2 or x4 mode) supports CrossFire Technology.
thus is normal.

[JrRacinFan]

Ahhhh . . .

What is your crossfire score in 3Dm06?

[Gallatin]

with E2160@2.4Ghz, ram teamgroup 2x1 gb 800mhz ddr2, 2x3650 and vista ultimate x86 = 6700+
that is my girlfriend's pc.

[JrRacinFan]

Strange. My old pair of 2600's got me almost 7k. Well, I guess thats not too much difference.

[cdawall]

3650s are not quite as powerful as 2600s Jr

[JrRacinFan]

How so? I thought those cards were better than 2600XT's?

[cdawall]

no weaker core

[JrRacinFan]

O rly? I thought they were RV635, just a revision of the RV630 with a die shrink. Hmmmm .....
