GTX 480 SLI - screen jitter!

Hi, i took a video to show what is happening. i am new to sli so i dont really know what to check.

in the video, you can see the bottom of the screen bend and slightly wrap around like its an old television.

once i am in game in BC2 or JC2 there are no glitches. on the other hand, Guild Wars is completely glitched and i have to disable sli.

system:
silverstone strider 1000w
msi p55 gd85
i5 / 750 stock speed
8gb ddr3
msi gtx 480 - reference design (x2)
same bios on both
vists64
latest nvidia drivers
coolermaster Cosmos S
no heat issues...


on the off chance its the sli bridge, i ordered one from evga.

anyone have any ideas why the pre game / load screens are so glitched but the game runs ok?

hi, thanks for the reply, i am using a dual link dvi cable and never had this problem with my single 480 since august.

its possible there is an issue with one of the cards, but since single card mode works fine, i am not sure what to test beyond just swapping them.

one more thing occurs to me. i had a lot of stability problems with the original card until i upped the voltage about 2 steps. i will try this on the other card too...

new bridge arrived from EVGA. this fixed the problem 100% and supports what i heard about defective bridges from msi.

now if i could just keep my ss strider 1000w from overheating in furmark...

good to hear you got it working....

don't worry about something overheating in furmark...

it is likely that it won't overheat anywhere else...

PSU especially
