Short answer: It doesn't "switch" and you can't disable the Intel IGP. Long answer: From a hardware point of view the Intel IGP is always handling image output to the laptop's LCD screen. The NVIDIA GPU copies rendered graphics into the Intel IGP's frame buffer (which resides in system memory) when it is active. The Optimus software makes certain programs ...

How does PhysX work with SLI and multi-GPU configurations? + = Supported! When two, three, or four matched GPUs are working in SLI, PhysX runs on one GPU, while graphics rendering runs on all GPUs. The NVIDIA drivers optimize the available resources across all GPUs to balance PhysX computation and graphics rendering. Therefore users can expect much ...

The Intel integrated graphics adapter in your computer is most probably the source of the problem. The thread Force 4:3 ratio / pillarbox with 540M explains it : Your "problem" is not a problem at all but its the nature of your machine. You have an "Optimus" system which means you have an intel graphics processor and an Nvidia. You do not have ...

I would identify the main difference (if there was only one difference), but this link tells all the differences. I hope this helps.

Because of my new 660ti i can now answer my own question: Yes, you can use TwinView with 3 (maybe even 4) screens the same way you used it with 2 screens on older nvidia cards (testet with 3 screens: 2xDVI + 1xHDMI).

No that will not work, the GPU must be the same. From their FAQ: Can I mix and match graphics cards that have different GPUs? No. For example, an XXXGT cannot be paired with a XXXGTX in an SLI configuration.

I've used the creatively-named Video Memory Stress Test app a handful of times while twiddling my video card's VRAM speeds. Unlike g80memtest, it doesn't make use of CUDA (though it can!) and should work fine for your card. Like standard Memtest, a couple of hours should be sufficient to see if it actually is your VRAM causing the problem, or something else. ...

Your laptop has Nvidia Optimus Technology (Dell help page): NVIDIA Optimus technology (not available on 3D panel) NVIDIA® Optimus™ technology automatically optimizes your battery life while maintaining the graphics performance you expect — completely, seamlessly and transparently — whether you’re watching a movie, surfing the Web or ...

Sounds like the card is starting to go bad. The same thing happened to me recently with a GeForce 7300 in a HP Pavilion desktop (running Vista). In the BIOS screens and when running full-screen DOS applications there would be patterns of solid lines approximately like this across the whole screen: | | | | | | | | | | | | | | | | | ...

No. Your motherboard only needs SLI support if you want to run the graphics cards in an SLI configuration (which would only allow you to drive 2 monitors, possibly 3 if you're using nVidia's Surround technology). If you just want to have two cards operating independently and driving 4 independent displays in an extended or cloned desktop configuration, then ...

I think you are right on the borderline of safe. Have you checked both GPUs fans? Make sure they are not clogged up. Also, maybe you should try air dusting your computer with a can of air. I would take all precautions. UPDATE: Forgot to mention something... There have been mentions all over the GPU community of the solder joints melting due to high amounts ...

From some AMD presentation: Each SIMD unit contains 16 stream cores, and each stream core houses five processing elements. Thus, each compute unit in the ATI Radeon HD 5870 has 80 (16 × 5) processing elements. Analogue for CUDA core is Stream core, and SIMD unit is analogue to nVidia's Streaming Multiprocessor. The difference between CUDA core and ...

download this Tool GPU-Z and run it. It will read all the data of your GPU and show you your memory.

On the NVidia Control Panel you can choose which graphic card to use, but you can not know which graphic card is running. If you just want to know which graphic card is running, you can have an icon in the notification area which show the running graphic card. Here is the explanation to enable it according to acer website: 1 - Click Start and then ...

This article treats how the GTS 250 stacks against the Radeon HD 4870 (and others). It contains this comparison chart that tells you everything technical that you ever wanted to know and were afraid to ask about. More importantly, it contains detailed performance analysis for different screen resolutions in the section First-Person 3D Shooters. My personal ...

DVI-D is what most monitors take - it is the pure digital signal. DVI-A is just the analogue signals, as would be found on VGA' d-stub connector. This is rarely seen. DVI-I carries both the digital and analogue signals. This is what most video cards output, so you can either connect the output port directly to a DVI-D or DVI-I port on a monitor or through ...

RivaTuner lets you do lots of cool things with nVidia cards. You could also turn off the Aero effects, and go back to "classic" Windows (I don't remember exactly how it's named in 7 right now).

If you have an older G80-based 8800GTS, your card runs hot and you will need to add case exhaust ventilation below the card, and an additional input fan to provide supply air for balance. I know, I had a well-balanced, cool running system with a G92 based 8800GT and all kinds of overheat problems when I upgraded it to a G80 8800 Ultra. Adding two low case ...

They should work just fine. I think the limiting factor (and the reason I think this is a bad plan) is the use of a KVM. Most KVMs I'm aware of seriously hurt video bandwidth (make the image fuzzier / less sharp), which would be kind of a waste w/r/t the fancy video cards. Sure, SLI would be nice, but if the two graphics cards have a distinct enough ...

There shouldn't be any problems running the two cards together with NVIDIA's drivers, but as others have mentioned, SLI won't work. You could use one card for physX and one for video as explained here.

The long and short is: on most OS (windows[xp|2k|v|7], Linux, etc), yes, as long as your motherboard has enough slots. I've done this with completely different cards (matrox, ati, nvidia, trident, intel, cirrus, etc) in various linux distros and windows versions. Linux handles it pretty seamlessly, whether it's different cards from the same vendor, or ...

No, it does not need to be the same model, or even the same brand. I have a few clients using competing brands of video cards in one computer to support multiple displays, and it seems to work fine for them. This doesn't mean that two specific brands/models might not be compatible though (you'll have to test for driver conflicts; make sure that whoever you'...

I am not familiar with this particular laptop, but there is very often an option in the BIOS to specify either Optimus graphics, or to force either the Intel or Nvidia card to be dominant. That would completely disable the one chipset.

Hey I had the same problem for some time! I just installed forceware 72.14 and it works flawlessly for my Drivers for NVIDIA GeForce4 MX 440 (pci) on Windows 7. Before running the setup i had to set to compatibility mode for Xp SP3

Nvidia stopped support for their Nvidia System Tools on April 2010 (almost three years ago at the time of writing this). I attempted to use it with my GTX 560 Ti, and it did not work correctly (could only change clock speeds and not voltages, and it would not save any of my profiles properly). Fortunately, you can use either of the freeware tools EVGA ...

After some googling I found this thread of people having the same problem. There, disabling hardware acceleration in Flash seems to help. The other suggestion was to downgrade the driver, as it seems to be a conflict between newer Nvidia drivers and Flash Player. You could at least ease some symptoms by enabling HTML5 video on the sites that support it (...

The easiest way to look it up is to use System Info. Start > Run (or Win+R) > MSINFO32 Under Components, look for Display click it, and it will give you info about what windows is using.

While I'm not sure what "guides" you're referring to, I'm guessing that when people recommend manually updating drivers (or software), they're saying that you should initiate the installation, instead of letting it happen auto-magically in the background. This advice is mainly so that you're aware of your system configuration, and if something breaks, it'...

Are you sure that your system goes haywire at GPU's temperature going over 65°C? Because in my opinion, 65°C is not hot. Hot is when GPU reaches 80-90°C. Even then it works. I believe the problem is somewhere else. Just to be sure, blow any dirt off of the heat sink. If you feel comfortable you could remove the heat sink and replace the thermal paste. Then ...

I'm an idiot and not plugging things into the graphics card does indeed mean it's not being used. Solution: go buy another HDMI cable. UPDATE: Bought an HDMI to DVI cable and graphics card is now under load when playing games, and can run Mirror's Edge at max settings with no noticeable frame issues. Not much of a claim to fame but it's the only thing I ...
