Hello.
I have a week old pc consisting of:
- Asus Maximus 6 Formula
- EKG watercooling
- Asus blu-ray writer
- Sychte flat fan-controller
- 16GB of Corsair Vengeance pro 2400mhz memory
- Intel i7 4770k
- Fortrom Aurum Pro 1000w psu
- 2x EVGA GTX 780Ti Hydro Copper Classified.
- 3x LG EA27" IPS 1080p monitors
- 1x Corsair SSD
- 1x WD 3Tb HDD
in a Corsair Air 540D
 
Computer worked great with the 335.23 Driver and The R331 that came with the Gpus.
- Updated to the Beta driver because of all the socalled improvements it would make.
* Everything seemed to work right.
- Exept for when i was trying to play Metro LL, the game freezez in the first chapter where you take a elevator upwards after gearing up.
After the freeze, the message i get while at the desktop is that the nvidia driver had to close and was recovered after an error.
- this happened 3times and i therefor thougt it would be a good idea to go back to one of the older drivers.
* Downloaded the driver packade 335.23 from geforce.com since i couldnt find a way to do it within gf-experience.
- Did a clean install like allways and tried to run a benchmark afterwards with unigine valley just to see it working.
Now the real problems begin (sorry for the long intro but i am really upset by all this)
* Unigine would not start, the drivers failed right when you could see the fps counter in the top right corner. (it was possible to configure surround and activate SLI in GF-Controlpanel).
* Tried to run opengl and dx 11 and 10. but none would run more than a fraction of a second.
- i eventually restarted the pc to se if it helpet, but no.
- tried different methods of reinstalling drivers.
* still same problem
- then after a few tries when i was rebooting after all nvidia drivers was uninstalled i could not get a picture up on my monitors. not even the ROG Post screen. The screens activates as the computer starts but nothing shows up, it then fades out to sleep and never changes. The motherboard throws an IDE idle code. A2
- Have tried everything, unplugging monitors and plugging them back in as pc was running.
- Changed outputs on the gpus.
* I got the screen back when i unplugged both cards and only ran from the motherboards gpu.
- tried to change a lot of settings in bios, such as pci lane speeds, hibernation behavior and deactivating windows safe-boot etc. but noen would work. every time i plug in the gpus the screens behave the same. nothing!
- i then tried to unplug only the top gpu. then i could get a picture. i then installed the geforce drivers.
- shut down the pc and plugged in the other card. pc then would not show post.
im getting frustradet by this and was really looking forward to maxing out all games.
 
Oh i almost forgot, i tried to reset cmos, rolled back the bios version since i updated it a few days ago. and did a clean install of windows on my ssd.
 
BTW: i got 47fps in unigine at best with 4x aa and 5840x1080 and ultra settings. is this normal?
and with metro:ll`s integrated benchmark i got as low as 7fps with physx on and 23 with it off everything maxed. is this also normal? with physx on the game is not playable. not even at lower settings.
Hope to hear a solution to my agony.
Best regards: Bjørnar B. @ Norway :)

Thanx:)
 
ok so i cant find any 4pin "molex"? ecept for the ATX connector witch i didnt use, instead i used the 8pin atx connector according to the mb manual.
and my atx connectors is at the very top-left of my mb.
 
Also had a look at my 24pin atx connector. absolutley no signs of burning or melting, has never been any smells either from the pc. nor smoke.
 
My loop is like this: Res-Pump-360mm rad-gpu2-gpu1-chipset-cpu-Res.
- The Graphix hav never been hotter than 51deg celcius, and this in unigine valley benchmarking. the problem card have at most been 2deg hotter than the first.
And the cards have never been OC-d because why...
 
i would have thought it shouldnt be possible to kill a card only by driver error.
- is this covered by warranty then?

When testing, disconnect ALL monitors completely from the videocards
Use ONLY one cable attached to the primary GPU (top slot) and ONE monitor (nothing else)
 
From your description it is difficult to tell what happened
 Have you checked that the top card is properly seated and that its not twisting because of hose connections?
Got another SLI bridge.. try it as well
 
You could have PCIE slot failure or the card in question might have died.... hard to tell
 
Just what OS version are you using?
 
As for pumping 53c water over your 4770k CPU..... 
 

I know this is a pain but is there anyway to try only one card at a time in the top slot?

Its been tried. Works on one of the cards. The other never ouputs and wont be ok in device manager

OK so if you place one card at a time in the primary slot one card will work and the other doesn't. Is that correct?

Im thinking the card got bricked by the drivers. Am i thinking wrong? It had worked flawlessly untill that point.

The drivers will not brick the card.
