Problem with Nvidia SLI GTX 680

post #1 of 2
Thread Starter 
Hello,

Earlier this month i got a second GTX 680 to go with my MSI one. Basically they are both stock reference design non overclocked. So originally i ran them

MSI = Watercooled + CPU loop and the second GTX i ran aircooled. Connected with a single SLI bridge both cards worked fine. SLI worked fine no issues. SO my hardware arrived and i went on to watercool it. Had a serious issue retold here. http://www.overclock.net/t/1424852/videocard-gtx-680-worn-out-torx-t6-screw-which-is-stuck/50#post_20832233 . But i managed to fix it and yestarday i finally got around to installing it. Hooked up all the pipes everything is connected leak tested started it. No crosshair V formula error messages no beep codes no diagnostic lights. Everything is tip top. Put the PC upstairs hooked up started it and tested both cards. When i hook up a monitor to them both i get singnal on both of them. The cards have worked in SLI before. But suddenly in nivdia control panel there is no SLI configure option. IT just is not there. I tried re installing the driver.

Extra info.

These cards HAVE worked together before using the exact same configuration as they are using now. Now other hardware has been change both cards work and are detected under. Geforce xperience GPU-Z device manager and even Nvidia control panel ( i can change the physx adapter to one or the other) The darn SLI option just won't pop up. Any clues?

Hello again ladies and gents. Problem has been solved by the following.

Apperantly on my Crosshair V formula i've used the top and bottom slot. Which were x16 and x4x4. So it turns out Nvidia SLI 2 way cannot work with 4x4 it will never register it as capable card. So i just moved my entire card up one slot with the watercooling. (it created a kind of a cool pipe twirl it looks awesome and as far as i can tell no kinks it) And now it is MAXIMIZING MY 3D performance. Any way use this information wisely my friends to finish up the tread always write the answer if you found it. Hope my stupidity will guide you in the future to avoid my mistake.

Not the best quality but this is how it looks now as i moved it. Thanks to those of you who read this.
