Vista - Crossfire Setup

**Lomai** · 4 Weeks Ago

Hi All,

Looking forward to setup crossfire for the first time on my rig.
Specs are as follows:
Core i7 920, 2 x WDVR 150GB, 12GB DDR3, Corsair HX1000W and Vista HP x64/Win7 Ultimate X64- intend to crossfire two Sapphire R4890's.
Are there any issues I should be on the lookoput for? Can anyone also tell me the correct orientation for the crossfire connectors?

Look forward to any responses

Thanks

You can't run 3 monitors with CF enabled (I believe the same goes for SLI )

Two cards = Twice the noise. Twice the power usage as well.

Not all games scale well with CF/SLI. In fact some games run better with a single GPU. Again this is usually sorted by drivers and patches.

Generally speaking though, CF/SLI works very well and the performance increase can be very noticeable.

And you only need to use one crossfire bridge. This goes on the connectors closest to the rear of the case. It doesn't matter which way up it is.

As for the power connectors, for the first card use the 2 hardwired 6+2 pin plugs. For the second card, use the blue modular cables and connect them into the 12V1 rail. (That's the recommended load distribution by Corsair)

No worries mate

The second crossfire connection is intended for TRI and Quad crossfire setups.

Best of luck with it - despite the occasional annoyances with CF, it really can be worth it - especially if you like using xAA
