4870x2 flicking / stuttering

post #1 of 43
Thread Starter 
So I just got my 4870x2 yesterday and scored p16566 on 3dmark vantage. Now I'm starting to notice that it's flickering on the screen. What I'm trying to describe is it looks like when you record a CRT monitor and it's all wavy like on the screen. Even when not playing games browsing this forums I can see the wavy vertical lines. I know that it's not the monitor because when I plug my laptop in via hdmi it does not happen. I am connecting my video card via VGA cable with dvi adapter. What's really weird is when I plug my gts 250 back in it also happens! I did try to re-sit the gfx card but it still happens. Could it be a motherboard problem? I'm waiting for my dvi cables to be delivered so I can't test that yet. Any help will be appreciated!

I am using the latest drivers. The refresh rate is at 75? Apparently that's max for my monitor according to ccc. The res is at 1920x1080

I just received my visiontek 4870x2 refurb and I do have some problem.
My 3d vantage gpu score was little over 17000, so I do not see any performance issue, but it glitches in my favorite game World of Warcraft.

I think my card is bad
Tigerdirct does not have anymore in stock, so there is no chance of getting a replacement.
I am going to call visiontek on monday.

My logic says that if the card had any issues that wouldnt be the output.

I would disable everything on the CCC and if that doesnt work, try with other drivers, then try some other stuff, and then maybe start thinking it might be the card.

RMA it if you can get them to accept it..I don't think they have any to send you back so they should send you a newer card..
