Sli bridge issue

I'm having a weird issue with my sli bridge that is a specific card is in the top slot the sli bridge doesn't make a good connection and there's artifacting. When I switch the cards around the issue seems to disappear. I had to wiggle the sli bridge because some games were flashing colors which is due to the "loose" sli bridge.

I'm also getting epilepsy inducing artifacting or something else is skyrim where these bright colors will flash or spike out and textures flash or flicker. I wasn't sure if that was due to my graphics hardware or the enb mod but I don't remember it doing that prior to installing the enb mod so it might not have to do with the sli. Oh both gpu's are essentially the same mode but with differing bios versions. One is an AR model EVGA 1GB GTX 460 superclocked EE and the other is a TR model.

Any thoughts or remedies and should I buy a new sli bridge? The sli bridge is the Asus bridge that came with my Sabertooth X58 motherboard. I was wondering if it's possible to flash the card with the outdated bios with the bios revision from the other GTX 460?

Thanks.

I also wanted to chime back to say I believe I'm experience worse performance than I should. My hardware may not be the greatest or is considered good nowadays but I get lower fps than I should especially when I have sli mode enabled. My fps was lower than it should be but seems to deteriorated further over the years with new drivers.

Switch gpu's back around in pci-e slot and issue goes away lol.

Can anyone tell me if there's bios updates for my Evga Geforce GTX 460 superclocked EE and how to flash. I think my issues (slowdowns, stuttering, low performance) may be bios related if not a faulty gpu due to one gpu being an AR model and the other a TR model with different bios versions. Ever since I got the TR model was when my issues started and I noticed when I got the TR card the heatsink screws were lower quality and not spring retensioned. I had no issues with the prior secondary AR card until I sold it and bought the TR as a replacement.

Thanks.

Well this is weird..

After switching the gpu's to the opposite slots Crysis 3 got a huge boost with very high settings and that's with only a single card. I also changed power management mode in Nvidia control panel to prefer maximum performance globally. However the latter doesn't seem to have anything to do with it since I tried that before.

I'm not sure what is going on unless one gpu is bad but which? It's tricky to diagnose since it occurs in sli mode and only with the cards each in a specific pci-e slot. Anyone have any clue as to what is going on here?

While performance improved in certain games and some graphic anomalies are gone the slowdown I am experiencing with The Evil Within in sli mode is still there.

So I'm just gonna presume everyone is as frazzled about this as I am?
Most people's fix would likely be to stick to a single GPU. SLI is rare, its issues not easily worked around and the pool of user knowledge minuscule. It's concentrated at Nvidia's official forum and hardware enthusiast forums, so that's probably the best places to ask around for SLI issues.

So after switching the gpu's around to opposite slots and installing the latest Nvidia drivers I am getting quite awesome performance in games. Sli'ing these GTX 460's paid off for nearly 5+ years of gaming so far. Too bad devs are too lazy to implement true sli support in their titles which leads to Nvidia releasing a half-assed sli profile forcing single gpu. If devs would (properly) support sli and fix sli issues such as atrocious slowdowns in Tomb Raider with TressFX enabled and support sli in idtech5 games I'd be set for a while longer.

As for my issues I'm just going to note the lack of response as everyone being as stumped as I am on this. ;)

If developers would support sli it wouldn't be half bad and good to future proof without worrying about replacing a gpu too often. The games that are optimized and support sli run great and likely even better if not the fact something odd is going on with one gpu. Some might have bottomless pockets but a single gpu costs around as much as a console. With sli I didn't have to worry about the cost of upgrading my gpu and has went strong for about five years now. I spent money I shouldn't have and couldn't really afford when I replaced the motherboard thrice out of pocket. I was quite surprised when Asus said they'd replace my Sabertooth X58 so I could finally use my i7 and sli'd gpu's again. So for a while I'd like not to worry about shelling out for hardware unless something fails. In fact I want to enjoy my system rather than messing with hardware and hope nothing fails for at least the next two or three years.

If I could afford it I'd get a single GTX 780 or GTX 980 but why bother when I don't have money and sli'ing my GTX 460's works well for the games I have? The issue here is not sli but the fact something odd is going on with one gpu that leads to strange behavior depending on the pci-e slot each gpu is in.
