    I've been a fan of ATI (AMD) for close to 20 years :) I've had just about every flavor I think. Until this past year, I usually did try to overlay the drivers, and just ended up doing clean installs. I resigned to clean installs a year or so ago and have been doing it ever since without any problems.

    I suspect you may be right. Once the cards are installed properly once, removal of drivers and then installing new drivers, may be a fine practice as the devices have properly been enumerated in the system. I'll let you know, AMD is due for a new set soon!

    Angry Re: 6970 Crossfire on Extreme7 Gen3 Poor Performance.

    Hi Iíve not had time yet to read all this thread, but i have been to hell and back with this extreme7 board, First I got the extreme4 Gen1 on release date fantastic board and runs crossfire no problem, but as I run eyefinity some games struggle at 5760x1200 so I had been waiting for the extreme7 to trifire 6950ís or 70ís when flashed. So I got the new board thinking it would work no problem with the nf200 chip so after setting up the system with 3 cards I was getting massive amounts of screen tearing and lag/frame drops in all game so running 2 cards would reduce the problems by half, BUT a single card would run perfect and give me a massive difference in performance over a single card in my extreme4.. Anyway I canít find a fix for the board as I have used a different CPU,RAM,HHD,PSU even case lol but canít find a way to get crossfire/trifire and eyefinity to run well at all.. On another note not that I did much testing a single screen was ok but I get the same fps now on 2 cards in my extreme4 setup so I need to swap boards again for testing.. Hmmm if I canít find a fix soon you will see this board on fire on utube! NO JOKE, lost 4 days last wk trying to solve it :s


    I did contact Asrock, they said contact my supplier and ask for a RMA etc, my supplier said if i have had the board over 7 days and i had it 20 i cant get a refund so Iím stuck with a nice looking door stop at the min lol

    Having spent that much time trying to fix your CrossfireX, I suggest taking the time to read this thread.

    Bottom line, I removed all the drivers, removed one card from the PC, installed the latest drivers to one card, and then put the 2nd card back into the box. I suggest you do the same, remove all the drivers and then install to one card, then add one card at a time to your system.

    My crossfire is smooth as ice now. Absolutely no problems with two 6970's.

    Thanks, i will give it a try this weekend, i really hope this works, it must be the only thing i didn't do if i remember correct..


    Even if it does work, its very strange how i can put the extreme4 board back in with the extreme7 windows installation on the hdd and it runs perfect :s anyway thanks for the advice as i really want this board to work as it really does look the biz :)

    Overlaying existing drivers was again buggy... it dropped my Windows Experience from 7.9 to 6.0.

    Removal of all drivers and installing to a single card wasn't clean either, however after disabling CrossfireX and then enabling it again I'm working.

    My current drivers upgrade/install thinking.. disable CrossfireX, remove existing drivers, install drivers, enable CrossfireX. You shouldn't need to remove hardware to upgrade drivers, it's not a good idea repeatedly, it would cause wear on components and promote system damage risks.
