Hi,
 
I just installed 2 GTX 690's into my Gigabyte P67A-UD7-B3 Motherboard, connected them with a single SLI bridge and fired up the computer.
 
For some odd reason the NVIDIA control center is telling me that I have a 3 way SLI configuration instead of a Quad-SLI configuration.  It is also telling me that my SLI setup is not optimal (lol).
 
I have tried installing the latest drivers, even re-installing them after Safe-Mode/Driver-Sweep etc.  - am I missing something?  I am relatively new to the enthusiast crowd and this has me completely stumped.
 
Any ideas?

Make sure the cards are in the right PCI-e slots to optimize speed.  not sure on the gigabyte but on the EVGA Z77 it is slot 2 and 4.   Uninstall everything, drivers etc.  Install only one card and then install the drivers.  Let the graphics card install and reboot into the OS.  Once you see the card and two GPUs in device manager.  Shut down the computer and install the second card.   Boot up the computer and let the computer find the second card.  Make sure that the device manger sees 4 GPUs.  SHut down the computer and put the SLI bridge on.   Boot up the computer and then look at what the NVIDIA control panel sees and then try to enable SLI.  You should then be ok.  Sometimes installing multiple GPUs cards with the SLI cable on confused the installation.  Try that. 



Make sure the cards have enough wattage. You will need 900 watts at full load.  From what i've been reading full load wattage is something like 450 watts per card.   They may be downclocking because of not enought juice.

545 watts on overclock


What power supply are you using and what other peripherals are drawing power?

Delirious,
 
Will a system with an AX1200 and two gtx690s and oc 2600k have enough juice?

It's putting it very close depending on how many fans you have, how many hard drives, and what sort of overclock.  Don't quote me but I think that the 3770K will be something like 70 watts overclock.  You will have to look up the wattage of an overclocked 2600K.

If I were building a quad system with these, I would purchase the 1500 watt PSU or have a 1200 and an extra 600 watt at least and dedicate it for the second card.   Not having two,  I can only assume based upon anandtech's review.
 
 

 I posted a few graphs using metro as a load vs. OC load.   I can't really say as I don't have a practical way of gauging but from those graphs, you see what you see and if your getting 500-520 watts folding, multiply that by two for quad SLI...but then you don't fold in quad SLI, you set up folding differently if you want to use all GPU cores.  Anyways.  I've seen another guy on here with Quad.  I'd look at what he is using.

Crezno. Are you using the 600 watt in your signature, cause if you are, I'm wondering if the 690 isn't throtteling.

Display not optimized probably means that the display resolution isn't set to native resolution

So that fixed the quad SLI setup? I've had to install my last two quad SLI that way as installation was quirky.

BTW, ID LOVE to have your problems right now

Yea Im using the 600 Watt that comes with the SG08B.  If you check out some reviews on the case, they tested out the PSU, and it tested 700Watts before the safety shut it off, and actually could have received a silver rating. The draw was tested off the 12v rail.
 
But if its throttling, I probably wouldnt be getting the FPS i am in my setup.  Its a very power efficient card. Im not 100% it isnt throttling, if it is I have alot more performance to be had haha.
 
This review shows the power usage of the 690 Alone to be 270 Watts, rather then the ~470 in the charts posted above, thats total system usage.

Total GPU usage will be at roughly max 300 watts so an 800 watt PSU should be fine although I like overkill.

The thing that pops up that's says the display is not optimized is just saying that you are not running at 16 x 16 PCIe. So you can ignore that one. At least that's what I think it means.

sorry links don't appear...
u can use driver 301.40 available on guru3D

I've tried this and my Nvidia Control Panel still shows 3-way sli, but if I go to my PhysX settings pull down menu it shows both gtx 690s (GTX 690 1-A, GTX 6901-B, GTX 690 2-A, GTX 6902-B). It's also using GTX 690 1-A for my Physx. I've uninstalled my drivers twice and followed your suggestion twice (taking out 2nd card, booting up, reinstalling, etc), but still not running quad sli.
My Display Manager also shows 4 GTX 690s.
Both of my cards are in slots 1 & 4 (both x16). I also have a soundcard in slot 3. My specs are below:
 
i7 3930k (stock for now)
Rampage IV Extreme
32gb G. Skills 2400
2 x GTX 690
2 x Intel 520 240gb
AX 1200
 

I think you're reading too far into what is actually wrong. I re-read the thread and I'm sorry if I missed your monitor config, but I don't see any information on it. Any time I can't properly enable Quad-SLI, it's because I've plugged an extra monitor into a port I shouldn't have. 
 
If you are running surround and using 3 or more GPUs, examine the nvidia control panel under Multi-GPU carefully. 
Every single monitor must be on its own dedicated GPU.
 
On the back of your 690, ports located on one "slot" are connected internally to one GPU. When connecting multiple monitors, connect them down the back of your case, not side-by-side.
 
For more info on connector recommendations, see:

Hope you can go "quad" soon.


 
 
 
 

OK, I did some testing with multiple monitors (six) connected to the 690 SLI setup that had the weird behavior as described above, so here are the results:

Actual setup is:

1-A
DVI 1: BBY LCD TV
DVI 2: Apple Cinema HD
Mini-Display Port: Nothing

1-B
DVI 3: Dell U3011 (2 of 2)

2-A
DVI 1: Dell U3011 (1 of 2)
DVI 2: Samsung SyncMaster
Mini-Display Port: Nothing

2-B
DVI 3: HP ZR24w


But NVIDIA Control Panel shows:

1-A
DVI 1: Apple Cinema HD
DVI 2: Dell U3011 (2 of 2)
Mini-Display Port: Nothing

1-B
DVI 3: BBY LCD TV

2-A
DVI 1: Samsung SyncMaster
DVI 2: HP ZR24w
Mini-Display Port: Nothing

2-B
DVI 3: Dell U3011 (1 of 2)

In other words, the pattern is like this:

Whatever is actually in DVI 1, will be seen in DVI 3.
Whatever is actually in DVI 2, will be seen in DVI 1.
Whatever is actually in DVI 3, will be seen in DVI 2.

Put simply, the ports are being detected as if they are shifted by negative one positions (with 1 wrapping back around to 3).

I have no idea how something would appear if it were connected to the Mini-Display ports, since all my monitors use DVI cables.

Activating SLI causes only the Apple Cinema HD and Dell U3011 (2 of 2) to display (the other four monitors go black). I'm assuming what *should* happen is, the two monitors in 1-A DVI 1 and 1-A DVI 2 should stay active, but what actually happens is the monitors in 1-A DVI 2 and 1-A DVI 3 remain active.
 
I'm assuming this is just a software bug in the nVidia control panel, because in spite of this weirdness, I do get good benchmarks when running the Heaven DX11 benchmark utility. However, it bugs me that the nVidia control panel warns that my setup is "not optimal," and I still need EVGA to look into this and let us know if it's just a control panel display bug, or if we should worry about it.

Again, the motherboard is Rampage IV Extreme, so this may be some weird thing only affecting 690 + Rampage IV Extreme configurations. Did any of you getting the "3-way SLI" message try plugging a monitor into the 2nd DVI port, to see if that makes the "Quad SLI" message appear, as in my case?

Hopefully this bug has nothing to do with functionality. As far as I can tell, it's only a control panel idiosyncrasy, but I want to be sure...

Interesting, but I have the extra 6-pin power plug plugged in already, and this strange behavior still occurs. Did you get the thing where it shows the monitors connected to the wrong ports in the nVidia control panel?

I tried testing again with the latest beta driver (304.48), and although the message about the setup not being optimal goes away, all other behavior remains the same.

Weird. I don't know if I can trust this build or not.

I had the same problem so I clicked the link on how to configure correctly and since I have a single monitor it was DVI port #2. ALso you can change the properties to optimize for a single monitor rather than multiple monitors
