Since the cards are two-slot widths, they expect that you'd use slots 1 and 3, and the included SLI bridge should accommodate that. If you want to use a wider spacing, you can get longer SLI bridges from nVidia:
The facts here are as follows:
SLI is successfully marked as enabled in the Nvidia Control Panel,
Video performance is bad.
If we couple these facts with the Nvidia article of
Introduction to SLI Technology
Although the bridge is not explicitly required to enable 2-way SLI with most GPUs, it provides a dedicated communication pathway for the ...
Crossfire/SLI is only usable with two of the "same card". That is, a GTX 550 TI with any other GTX 550 TI. The brand or manufacturer is not important to this (but can help for optimal performance). Keep in mind that you will be pegged to the maximum VRAM of the lesser card; for example, using SLI between a 1GB card and a 2GB card will net you a total usable ...
There is no 3rd party alternative, currently.
Note that Microsoft said DX12 should be able to combine AMD and nV GPUs to even unify VRAM.
See here .
In practical cases, it is know for instances where users preferred using a main Radeon card alongside a lesser Gefroce card that they were using purely for vendor-specific physx functionality.
As Ash said, you can't SLI 2 different models of video card. They can be different manufacturer's and have different clock speeds but they have to be the same model and memory size. http://www.geforce.com/whats-new/guides/introduction-to-sli-technology-guide#4

Motherboard supports SLI, so no problem there.
While the RM-650 isn't ideal for SLI in general, it's a fairly decent unit and has the required connectors (4x 6+2-pin PCIe). It should be able to provide the power for this specific situation. The MSI GTX970 will requires about 150-200W under load (tests at bit-tech and Guru3D), so should be okay.
If you want the two GPUs to share data, then SLI Bridge is recommended.
IIRC, it is actually possible to share data without SLI Bridge. But this is slower, as data must flow from 1 GPU to the PCIe then to the CPU then back to the other PCIe then finally to the other GPU.
If your purpose does not require sharing of data between the GPUs, then you can make ...
First off, check the output ports on one graphics card - it depends on the manufacturer. If I could guess, I'd say any high-end card right now would have at least three ports, but whether or not those ports are the right ones is up to you.
There are variables to consider.
Usually, a twin-card setup is far more expensive than a single-card setup. ...
Answering your questions.
GPU Memory is determined by the memory of your Graphics Card, system main GPU memory is determined by your primary graphics card. It's not capped by the motherboard.
SLI or Crossfire is good if you want to do the investment by parts, but i personally do not recommend because SLI or Crossfire doesn't give near double performance. If ...
Looks like some problem with the graphics card driver, the bus or the graphics card itself.
The graphic card works just like a printer, if you try to send raw text to it or any data that doesn't correspond to its protocol, it will print this data in the screen as text. It seems to me you are experiencing something like that.
Try updating the drivers and ...
If you are into gaming, I would suggest you just leave a small partition for windows.
For the sake of curiosity, why do you think you need a HyperVisor vs a regular linux distro? Is it because you feel you can make better use of the machine hardware?
Honestly if this is for gaming purposes I think the best is to keep windows and just boot into it when ...
As per the quoted NVIDIA FAQ, it wouldn't be possible to run another GTX 660 by itself alongside the 2-Way SLI GTX 660s:
'Yes, you can add an additional graphics card to your PC to connect two additional monitors. The additional graphics card must have a GPU that is different from your SLI GPUs and must be NVIDIA PhysX capable (GeForce 8 series and higher ...
This one is a driver bug, and worth reporting to NVidia / Microsoft.
Something to do with the fact that when in SLI, each card renders a portion of the screen, so the screen is 'carved up' into smaller pieces to facilitate this.
Within the software layer that determines where to draw live tiles on your screen, something is getting confused.
Well if price really doesn't matter to you then I'd advise you to use the money to get a SINGLE high-performance card, rather than dual SLI. Not all applications can be easily configured to run on both graphic cards. The performance increase won't be noticeable if the work you are doing doesn't even need that much alllocation!
More reasons: (Quote from ...
Graphics cards have never been able to "appear as one" device.
For many years we have had SLI and its AMD counterpart Crossfire which used two or more graphics cards to render a single scene, but this requires a bit of hardware and a lot of software support.
In essence the software gives both cards an exactly identical set of data, runs the graphics card ...
When SLI and Crossfire first appeared, due to patent rights, motherboards could work with either SLI or CF. You had to use driver hacks that allows you to do SLI on CF board and the vice-versa. After everything was legally settled, now any MB supports both of them. So it was a legal matter, not a technical in nature one. Technically, it was the drivers that ...
I'll try to simply explain each mode :
Maximize 3D Performance => Use both cards to render the image on-screen, for better performance, both screens should be connected on the same card (typical usage : games)
Span displays with Surround => Will make you two screens one (Only one surface) Uses SLI to dwraw the entire surface. Example usage : Run a game on ...
Okay, I got an answer by the nVIDIA FAQ:
Can I add a 3rd graphics card in my 2-way SLI enabled PC to connect more monitors?
Yes, you can add an additional graphics card to your PC to connect two
additional monitors. The additional graphics card must have a GPU that
is different from your SLI GPUs and must be NVIDIA PhysX capable
(GeForce 8 ...
Is it possible to use Nvidia cards with SLI alongside AMD Radeon cards
Since Vista windows supports multiple graphics drivers. That means that you can mix cards from different vendors. E.g. one Matrox card and one AMD card, or one AMD card and one Nvidia card.
Now that answers the first technical asked part (no Crossfire or SLI used, just ...
Here is my method:
Remove the graphic driver by using "revo uninstaller", this is going to put your Pc on sleep; then you can not do anything afterward, but don't panic.
Force power off your pc (hold your power button), then unplug the SLi bridge, switch your DP/HDMI cable into the second card.
The next step is power on your PC, now you can see your ...
This is a pretty broad question, but the cons (just as broad) could be like this:
SLI/Crossfire - require some tweaking, set up to work
Two cards require more power
Two cards Add heat
Two cards run two fans = a bit more noise
Most would suggest that one single more powerful card will give you less headache, work with more software, and use less power (...
You can run different cards in SLI with drivers patched with DifferentSLI Auto. But the first three characters of the PCI device ID must match, and in your case this would not work.
I would go with one video card. SLI, from what my friends and I have seen, is just too much of a hassle. This is due to bad support from games and other technical issues, such as the 2nd card not giving that much of a boost. The second cards cost/effectiveness is just to low, in my opinion.
