How do i enable onboard intel GMA 3100 with nvidia 8600gt
its showing me incompatible display adapter disabled when i installed the intel driver
it works fine in xp
when i read some forms they say that its a prob with WDDM
plz guys tell me how can i make them both work together

I didn't think you could. when you install the driver for the new 8600GT, it automatically disables the Onboard graphics. thats what I understood.

Why would you want the onboard graphics if you have got a graphics card installed? If you want to run 2 monitors, then your graphics card is more than capable of doing that. In fact, this feature has been on graphics cards for several years now, right back to the GeForce MX400 series (and possibly earlier). If your BIOS is configured and working correctly, when you have a graphics card installed it will detect this and automatically turn off the onboard graphics. Whether or not you have the drivers installed makes no difference as far as that goes since the card is detected during the POST before any drivers are loaded into RAM.

if onboard and external graphic card works together may be the performance will increase just 5% .in xp my on board and gc are working together and there is an improvement in games too.but in vista it is automatically disabling the driver of onboard showing incompitable display adapter found

I don't think you can do both..

someone correct us here. I'm pretty sure when you add a actual GFX card the computer disables the onboard graphics.. almost positive.

I'm pretty sure your right because my onboard graphics doesn't even show up in my device manager so its disabled.

Whenever an external video card is added to a system, then the internal one gets disabled automatically. As you can run either the add-on or the integrated one. If you want a dual display then would have to use a video card which has both VGA & DVI ports or would have to use a dongle.

Its one or the other my friend!!

integrated graphics is not really designed for gaming... but it allows the rig to function without a 3rd party video card.

Thats the main reason for me to get a graphics card.

 

[xguntherc]

told ya.. ya you can only use one or the other.. I'd use the 8600GT. or like I said in your other post. get a 8800GT for Crysis and your others games..

Correct,

If multiple graphics adapters are present in a system, all of them must use the same WDDM driver. If there are two graphics adapters with WDDM drivers from two different manufacturers, then Windows will disable one of them. The VGA adapter will be enabled, and the second device will be disabled.

MultiMonitor Support and Windows Vista

So even if you did manage somehow to enable the onboard Vista will only use one of them.

If I understand you right this function is only available on certain motherboards, (eg Asus M3N-HT Deluxe/HDMI) where the graphic card (nvidia 8600gt) does the graphics for gaming and the onboard chip (intel GMA 3100) does the 2d graphics. This is thought of as a way to save power. The same hybrid SLI technology also allows the two to work together.

If you have a motherboard that is designed for this I would recomend that you look in your manufactures handbook. Also note a bios update may be necessary!

I hope this helps

Just curious, If I install a graphics card on an XP machine will it automaticlly disable on board like vista does or will I have to manually disable onboard.

>Normally The Graphic card will come first, I personally would always disable onboard graphic in the Bios when it is not needed.

Right and wrong,

Hybrid SLI® technology, based on NVIDIA’s industry-leading SLI technology, delivers multi-GPU (graphics processing unit) benefits when an NVIDIA® motherboard GPU is combined with an NVIDIA discrete GPU. Hybrid SLI increases graphics performance with GeForce® Boost and provides intelligent power management with HybridPower™.

Hybrid SLI only works with a motherboard with an onboard Nvidia GPU and a Nvidia graphics card, won't work with the Intel onboard. That and if you follow the link I posted previously if you tried it on Vista, Vista would disable the Intel driver in favor of the Nvidia driver.

yes we were both saying the same thing, I only used the original named card and on board device as examples that were already mentioned. perhaps unintentionally a little confusing.
