Question  crossfire on pcie x4 by jun

i just bought this here and put this card on crossfire but i just realize its on a pcie x4 and the first one is on x16, thou it seems there in no error showing on the catalyst control center so is this fine? will i still get the crossfire performance? and is there anything to do to get best performance?
thank you

Answer by andrewn on Wednesday, September 7, 2011
You will still get crossfire, but I believe there may be some loss of performance compared to e.g. a x8 x8 setup. Exactly how much impact that will be in the case of a 6770 I'm not sure however. It might be worth asking in the graphics card section of our forums at - someone there would probably be able to give you more specific details.

Thank you for letting us know, although ATi recommend 850W+ for crossfire.

Question  crossfiring by jun

i just ordered this item today to pair it with my existing graphics card, please advice a quick installation guide to do the crossfire, i mean do i just put the graphics card in and it will automatically detected by motherboard and the drivers will also auto update or i have to uninstall the driver first then put the graphics card in and insert the cd driver to install?
and i have corsair 600 watts psu, will this be sufficient for the 2x xfx 6770 to overclock it (i really hope so because i forgot to have a look on it)and at the moment my cpu (amd 955 be) is oveclocked from 3.2 - 3.45ghz and
please advise
thank you very much

To crossfire two cards:
Have previous drivers uninstalled.
Install both cards and connect them with the crossfire bridge.
Install latest catalyst drivers.

A minimum recommended PSU of 1000W is advised, although I know that the Corsair 850W (43907) is powering our 2xGTX570's in our showroom just fine

Question  How good? by armo

Hi, im new to building pc's but im after one mainly for BF3. So i ask will this graphics card be able to run new and future games on very high specs?

Answer by stewartz on Saturday, August 20, 2011
It should be able to it. But to be sure, I would recommend either a 560+ nVidia or a 69xx series ATI.
