6990 eyefinity and checkboarding

[CaluMoo]

I already made a post about this but that was pertaining to just Heaven as i had not tested my card with many other games, i originally thought i had corrected the problem by uninstalling a program called ultramon that gave me a task bar on all monitors, but the problem still happens with it uninstalled.

The problem is, when i play some games, a weird wobble effect happens and check boarding goes up the screen. it seems to me that maybe the crossfire is not working correctly?

That is a video of it happening in S.T.A.L.K.E.R Piriyat.
As you can see from the video this makes some games pretty much unplayable.
The weird thing is, it only happens in some games, for instance i can play counter strike source and Rift fine without it happening, but others it happen.

My system specs:

i7 920 D0 @ 3.8Ghz
Asus p6X58D-e
Corsair TX 950W
Kingston HyperX 6GB
HIS 6990 stock

The monitors i am using are the:

Prolite e2473 HDS
Acer GD245HD
Benq G2420HDB

I have had this card less than a week and im quite dissapointed at the fact i cannot enjoy games with it.

I have done a fresh install of the drivers after cleaning them out with drivesweeper in safe mode, i have done a windows repair to make sure it was not a directx issue.

Does anyone have any idea what is wrong with it?

Doesnt look like a crossfire problem, looks like artifacts produced due to mem or core running too high for what it can stand, ie sounds like an RMA job to me.

I guess it would only happen in some games as only some games stress the card enough to push it over the edge.

I thought it could be artifacting but it doesn't happen when i run furmark, i can run that in full screen mode 5960x1080 without a problem.
I think furmark should stress my system more, if you didn't see on the video, i set the settings in stalker to minimum so i doubt it would be stressing the card.

Also check if you get it with just one monitor and eyefinity disabled to rule that out.

When playing the game on a single monitor i do not get the issue, only when the three monitors are enables, i checked the game on each monitor separately.

Have you tried each monitor invidually?

Are all monitors running same resolution, refresh rate?

 

[CaluMoo]

Yes i have tested the game on each monitor individually, i did not experience the checkboarding in game when the game was run on the single mointors.
All monitors are running at 60hz(though one is capable of 120hz i turned it to 60hz in windows) and they are all running at 1920x1080 normally but when i enable eyefinity it treats them as one monitor and changes it to something like 5760x1080


Managed to fix it, after messing around with some of the cables, i took out the passive DVI cable and replace it with a HDMI cable and now eyefinity works correctly
