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 ...

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.

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'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. ...

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 ...

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: | | | | | | | | | | | | | | | | | ...

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

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).

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 ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...

Install GPU-Z and Core Temp to monitor your temperatures, because it sounds like you have an overheating problem. Keep them on-screen so you can see what the temperatures are; check frequently while doing whatever you normally do to cause the problem. The motherboard will kill power to the system if your GPU reaches 95C (According to the specs for the ...

I think I figured it out. I've never seen this before, so this is a good post to have on the web in case others see a similar scenario. I probably should have mentioned that I was running a hard wired USB mouse and a wireless keyboard. As it turns out, after trying a new video card and a couple other things, I ended up calling it quits. I booted up my ...

It's Windows itself using the GPU. The Desktop Window Manager is designed to use the GPU to give you all the fancy eye candy. Desktop Window Manager (DWM, previously Desktop Compositing Engine or DCE) is the window manager in Windows Vista, Windows 7 and Windows 8 that enables the use of hardware acceleration to render the graphical user interface of ...

0x1000007e = "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED". If updating/replacing the drivers/OS didn't help, then to me it seems you most likely have a busted graphics adapter and/or video RAM. Ensure graphics adapter's cooling apparatus is clean form dust, and working as it should. If the graphics adapter is integrated into the motherboard and uses system ...

According to this post you can use the same drivers as GT630, I would try installing those. My experience is that the driver installer checks if the installed hardware is supported before installing.
