    Hi,

    I wonder if anyone can help me. When I am in game playing the screen shakes. Is it a driver issue or hardware? I am running Dual 7970m CrossFireX. Turning off CrossFireX stops the shaking but it defeats the purpose of getting a dual 7970m o_O

    Shakes? Or flickering with verticle lines on screen?

    I'd point to the crossfire cable being faulty as problem goes away after disabling xfire. Try wrapping the whole cable lightly in elecrical contact tape. Worked 4 me when I had crossfire flickering screen

    Bottom part of the screen shakes left and right. There is also flickering with vertical lines. And sometimes the screen goes crazy going up to down. You think it's the crossfire cable?

    It could also be caused by graphics memory at odd clocks or faulty perhaps on the second card.

    Gah, I just got this back from RMA fixing a dead pixel. I guess I have to send it back again... sigh. I should have tested everything before sending it the first time.

    Sorry to hear that, you could try playing with your memory clocks to see if it really is the issue.

    MSI afterburner, it may need a little setup to get working though, if you are not confident then I think it's safer sending it in. It may let you at least lower the clocks out of the box though, so give it a download and try lowering the memory speed down to around 1000mhz from 1250mhz.

    Try the cable. Insulate it with electrical contact tape, if it fixes issue then they can just send u a new xfire cable, I hate returning my whole laptop for rma. Your symptoms sound like mine.

    Insulate the whole cable. Cause I only did part of the cable, it reduced the flickering by about half. Upon insulating all the cable xfire was flicker free and smooth

    Certainly worth a try, it's very possible it would cause this issue.

    So, I insulated the crossfirex cable the whole line. Still have the issues. Doesn't seem to help.

    Damn!

    I'd tinker to death until I found the problem...like trying just one card at a time to isolate the card with the fault. You tried a clean instal from scratch of the OS?

    You tried both our suggestions, if you try this and no luck rma unless anyone with other ideas can help. I feel your pain as I went through it recently. I fxed it at first, then the slave VGA completely died, so I sent it back and got 680ms sli. Plain sailing since.

    I know its not what u wanna hear, and the 400 extra I paid for the sli still hurts but no more probs. I have to say with the latset drivers the 7970ms were more powerful

    Thanks for the suggestions. I appreciate them. I would probably try to isolate the bad card at the next step. After that clean OS install with stock drivers. But, I have a feeling one of the card is bad.
