Have you got the latest nForce and GeForce drivers installed?

[sparkypaul2005]

Hi Kez
yes mate i have tried the latest nvidia drivers and still gives the same effect when sli is turned on

[nvening]

try some older ones

[sparkypaul2005]

Hi nvening

which older drivers would you suggest

[Kef9]

Check you have V Sync adjustment on.

[sparkypaul2005]

Hi Kef9

how and where do i check to see if the v sync is turned on

[Steve]

I don't think your problem is vsync. I presume the 'scrolling' is in 2D mode as well as games?

[sparkypaul2005]

Hi Kez

That is true it happens in 2d and 3d

[Steve]

Are there any BIOS updates out for that motherboard?

[sparkypaul2005]

Hi Kez

that was the first thing i did i have also emailed gigabyte and they said try their drivers on their website which i did and it still does the same.
Do i have to run at a certain screen res when in sli ???

[Steve]

Nope you should be able to run at whatever you like. :/

Isn't anyone else thinking that this is a hardware problem and so needs RMA?

Surely, they were built for each other and sold with each other so MUST work.

Only thing I can suggest is just starting with bare minimum over again, install windows and if it doesn't work then RMA it.

Hi Alexander
Thanks for the advice. I get on to the shop and see what pans out.

Ill be in touch

Hi everyone

Another query about this 3d1 card its says in the manually that it will not run without the 6 pin plug connected to the psu 12v supplies but i noticed this one does.
Do you think it would suggest that it is not getting its full amps from the psu

have you tried moving your monitor further away from the PC? If it is interference this may help. No idea on the 6 pin plug question tho
