Deactivation of 2nd graphic card

I´m using 2 different graphic cards in my MacPro. The 2nd card is used in Windows only, but the fans are running at full speed under OS X.
Is there a way to deactivate the card in Tiger?
Thanks

You could take the windows card out, but otherwise hatter is right you cant get the fan to shut off, that is part of why I went up to 4870.

!!! Problem with 2nd graphic card !!!

Hi I have a big problem with my laptop.
I have an HP TouchSmart tm2-2000el Notebook, with Windows 7 64-bit.
2nd Graphic card is ATI RADEON HD Series 5450.
When I activate this hardware from Control Panel desktop goes black but every function are ok (sounds, illumination and all cmds).
So I must restart my computer in Safe Mode disactivate ATI Radeon HD 5450 and restart it.
Laptop run but only with Intel graphic card.
I tried to search update drivers on Amd/ATI site: amd online software reveals Ati radeon HD 5000 Series but after download Ati software tell me that is impossible to install drivers because there isn't an ATI Radeon HD 5000 Series.
So I have low graphics and CPU with 69°C because intel graphic card runs over...
I haven't found any driver for my model of laptop on HP Assistance.
Touchsmart spec
How can I do now?
Thanks
Alberto

This is the right driver for switchable graphics...do not also install the Intel only driver, you do not need both.

Installed 2nd graphics card in HP Pavillion Windows 8.1, but displays remain blank (no signal).

Model #: 500-314
Product #: F3E92AA#ABA
I just upgraded to a new HP, and need to run 4 displays. I purchased a 2nd video card (Radeon R7 240), installed it, overcame the secure boot issue, but the additional 2 displays are blank.
When I check for the graphic cards, it only shows the AMD Radeon R7 Graphics card.
Also, the R7 240 CD with the drivers, does not open. when I click on it. It just shows the little blue circle like its working on opening the program, but it does not open the program. So I went to the Radeon website and downloaded the drivers for the R7 240. It installed Catalyst, but still nothing.
What can I do to make this work?
Thank you

Hi:
When you install an add on graphics card, the onboard video is automatically disabled and cannot be enabled.
That info has been left off of the product specs page.
You can check to see if there is a BIOS setting to enable the onboard video but I doubt there is one.
I can't help you with why you are having issues with the add on card.
All I can say is that if you did not first uninstall the graphics drivers from the onboard graphics before you installed the new card, that is probably the problem.

[Xorg] Black screen with 2nd graphic card

Hi !
I'm a french (Sorry for my English) and new on ArchLinux.
I have a problem with my laptop, he have 2 graphics cards, the first one is an ATI Mobility Radeon HD4200 series and the second it's an ATI Radeon HD 5650.
The problem is when I want to use the second card, I have a black screen when I start X. It's the same problem with ATI driver and xf86-video-ati driver even if my card is detected with "lspci" and by "aticonfig --list-adapters" with catalyst driver.
If you need, this is my Xorg log :
Xorg.log with catalyst
Xorg.log with free driver
And if you want my xorg.conf , very basic.
Thanks for your help.

I use one card and found I needed catalyst-dkms pkg as well as catalyst & catalyst-utils
Hope this helps.

2nd graphics card doesn't work after upgrade to 10.6

I ordered my Mac Pro with two ATI Radeon HD 2600 XT graphic cards and they always worked great. After I upgraded to Snow Leopard, it always shows a display connected to the second card even when there isn't. This wasn't an issue until I started having windows displayed on that "ghost" screen that I couldn't see. In the System Profiler, It no longer recognizes the graphics card like it should and reports the wrong amount of memory (1024 instead of 256MB... I wish) and of course reports a "Display" that doesn't exist. Since from time to time I like to connect my TV to my Mac - for movies or whatever else - I connect it to this second graphics card but since 10.6, it hasn't worked.
In short: my second graphics card isn't recognized correctly; it has a ghost display with or without a display connected to it; will not connect to a display.

I'd assume you do have a bad card now. Maybe wait and see if newer ATI cards come out, or opt for 4870 or flash one of the 1GB models that can be flashed, and save couple $100.

2nd Graphic card displays white only if used for Video Preview in FCP

I just bought a Vavida 8800 graphics card, so that I could connect 3 monitors total. I have my main two monitors on my table connected to the Navida, and a flatscreen TV behind me in the living room connected to the original Redeaon graphics card. All 3 monitors display fine, but when I try to set the Video Preview in FCP, either on RAW or Full Screen, all I get is a white Image. This worked fine with only 2 monitors.
Does anyone have any ideas?
Christian

Does anyone know if Apple is working on the second graphic card issue in FCP?
I installed an ATI 3870 on top of the 2600 that came with my MacPro, assuming that it will work.
But I'm having all kinds of problems in FCP, random freezes, long waits for rendering and exporting, etc.
I have two Dell 24 inches monitors and a smaller 19 inches Acer, and I would love to have some extra real estate to leave the timeline in one Dell, the preview in another, and the canvas and viewer on the Acer.
I read I can get the Blackmagic Intensity to output HDMI/DVI (via an adapter, I guess, since the Blackmagic has no DVI output and my monitors have no HDMI), so my question is: if I get the Blackmagic can I use it's output for other programs (Photoshop, ProTools, and so on)? or it will only appear as a valid output in FCP? In other words, does the Blackmagic works as a graphic card when FCP is not active?
Sorry for the silly question, but I already bought a card that is actually useless for me, and I don't want to spend $250 in another.
Thanks

How to disable 2nd graphic card?

I have a laptop Sony VGN-Z21XN/B with two graphic cards:
1) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
2) 01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9300M GS] (rev a1)
Unfortunately both are running at the same time so my laptop is hot, noisy and the battery is discharged very soon. Is there any possibility how to permanently disable nVidia graphic card somewhere in system? I already tried disable nVidia modules in rc.conf, but without result and google doesn't help
Thank for advice.

I've just checked my bios settings and there is no option to set or disable graphic card. Bios is actually very poor.
The problem is that sony provides only windows (vista and 7, not XP) software switch so there is no HW support for switching... I am looking for something like disable hardware in windows device manager. Simply tell arch: don't use that stupid piece of crap...
However I'll have a look to site that you posted

K8N Platinum SLI 2nd graphics card problem

I just purchased a second SLI card MSI NX6600GT-TD128 and installed it in the first PCI-E slot moving my old MSI NX6600GT down to the second slot. The MB is in the topic header and the SLI mode chip is set to SLI. I'm running Windows XP x64 with 81.98 forceware drivers and windows recognizes the second card and everything is running in multi-GPU mode just fine.
Finally my problem with all this is the fan on the card in the second slot will not run! This is the card that I was using before and was working without issue. The second slot does not seem to kick on the fan for any reason so obviously the card starts to run really hot if I run a game using SLI. I had a card in this slot before that I believed was defective since artifacts started to appear after a couple of heat failures and I think it's because the fan never ran. Is there some setting I'm missing to get that fan going?
Bios is at v3.4 by the way. I haven't seen any of the more current bios address this issue so I haven't flashed it.

As you have tried both cards in the second slot, and both give the same results, ie fan not working, but fans work when installed on the first slot, then I would say thet the second PCI-e slot is faulty.
I would not suggest running a blower fan facing the second card as a workaround to the problem, In my rig the second card always runs a few degrees hotter than the first card. Yes you could connect the fan to the PSU, you can buy adaptor leads to do this, if thats the route you wish to follow. But if I was you, I'd contact the supplier for your mobo, and arrange to get it exchanged. I very much doubt that the extra current draw for a Fan to work is caused by the PSU as you have said that the card itself works fine in SLI mode with no artifacts appearing. And as you have not reported any other problems with your rig, it points towards the slot. Protect the investment you've made on the card, and get the mobo fixed / exchanged.
Your PSU is ok for now, but shortlist a new one for your next upgrade.
Let us know how you get on.

How do I use the secondary graphics card on a mac book pro with retina display?

I know that this is kind of a stupid question but I am new to dual graphics cards and this is the first mac that I have ever had, so I don't understand how you use the 2nd graphics card. When I click on the apple logo and go to about it shows the Intel Graphics HD 4000, but I know that they put an Nvida in here to so how do I access that? Because it has a lot more graphic power than the intel does.

Try opening iPhoto and then consulting the More Info... item. That app will cause an autoswitch to the big GPU.
Same will happen with any other app that requires that kind of display driving power.

Qosmio X300-14P : Graphic card issues and vertical stripes on display

Hi,
2 days ago, after a long notebook session of many many hours, suddenly after playing for 2 hours the game
Patrician 4 addon, it crashed in a strange and never seen before way:
The display would show strange and weird colours in all forms rushing over ther display. You could not recognize anything anymore, and after a few seconds of this the screen and the x300-14P completely froze/crashed (hung - no reaction on anything except power plug pull and/or 5 seconds push of ther power button).
I was afraid since this to me looked like a serious issue of either graphic card (nvidia chip) or display.
I hoped it was because of heat (though i have a powerful cooling pad below the notebook and heat shouldnt be a problem).
Next day (yesterday) I launched the game immediately after startup, and after a few seconds the same crash appeared again with the same strange video glitches (never saw something strange like that before).
I immediately did the 5 second power button press reset,. and then, when the first boot screen appears (the bios display hint and the loading/booting screen), there were like 2-7 vertical white stripes (on the black background) on the right side of the screen.
They wouldn't move nor go away.
I immediately turned the notebook off and it is off since then.
To me this looks really serious, as if either nvidia chip (Geforce 9800-GTX) is broken or the display.
Does anyone know something about this ?
Has anyone heard of such a problem ?
Who knows more ?
I know, i can now connect an external monitor.
If there is no problem, this should mean that it is a x300 display problem
If the problem also appears on the external monitor, it is the nvidia gpu chip. That would be at least my guess.
Has anyone any idea about this, what it might be and what i could do ?
(i am afraid sending the x300 in to toshiba for fixing is not worth it, as it is pretty old
(it was purchased new in june 2009). fixing it is probably too expensive.
Any ideas about hthis problem ?
I never had it before.
Who can help ?
Thanks
P.S:
I was thinlking about buying the new qosmio X870, but i just saw it has no express card slot, which i need for various expansion modules (like tv and video equipment, more e-sata cards etc.pp.).
Without an express card slot i wouldn't buy any notebook, i need this slot urgently (it is like a pci-express card connection slot in a desktop pc).
To me the express card slot is vital.
Too bad many notebooks dont have it anymore.
So io might need my x300 for some time,
but what shoudl i do abpout this new strange video chip/display problem ?

Hi,
yes.
even windows has now deactivated the whole graphic card, saying it was deactivated because
it reported an error - CODE 43 .
the stripes are still there at boot screen and bios screen, they go away though as soon as windows loads,
but this has deacvtivated the nvidia chip (the nvidia device driver software wouldnt start at all, it says : no nvidia gpu connected (since it was deactivated by windows 7)).
looks like i have to send the x300 to toshiba for repair (maybe even mainboard replacement).
who knows how i can find the local toshiba repair company ?
whom can i call in
FRANKFURT AM MAIN
GERMANY
to get my toshiba notebook repaired ?
if someone has the adress and even better telephone nummber, i would be happy.
a second question, by the way :
did someone of you ever replace the mainboard in a toshiba X300 / X305 ?
how expensive was that ?
thanks

Need a OS X-friendly graphics card

I upgraded my G3 B/W's processor to a G4 processor using a Daystar upgrade kit (MAChSpeedZIF, which works very well), and loaded OS X on the computer. But when running OS X the 2nd graphics card, which is a ATI Xclaim 3-D, just doesn't work--it's showing black and white, and beyond that it looks like ****. It runs well, in color, only in OS 9.2.2. Any suggestions on a new inexpensive graphics card that I can replace the ATI card with? The new card, like the ATI, will be used solely to drive a second monitor for internet browsing.

Cogitator,
it depends on your budget. I picked up last week (from the U.S.), a brand new ATI Radeon 64mb (the one with the S-video, VGA, and the second monitor) output), for about 65 dollars US with full warranty, in the box.
You might as well find a non working B&W G3 on eBay (i got two yesterday in Australia, one working and one would not start up, for a total of AUD 21.27!), and pull the ATI Rage out of that, keeping the rest as spares for your existing system.
cheers

An additional graphics card?

Hi, my mac pro is outfitted with the Radeon 4870 and I'd like to connect a 2nd 30 inch monitor to the computer. Do I need to install a 2nd graphics card? Or Can I use that MiniDisplay Port to Dual-Link DVI connector thing to "free ride" a 2nd 30 inch off the existing graphics card? And if I need to install a 2nd graphics card, must I be constrained only to getting another one of those GT 120 graphics cards? I will probably be connecting a Samsung 30" monitor and the majority of my work is photo proofing for professional output.

Two 30" monitors? I'd do some research on that before buying. I'm not sure the mini-display port is up for a thirty inch. With the lesser expensive adapters from Apple that I tried, I couldn't get the highest resolutions. the DVI connection will do fine, but that mini is problem prone. Even Apples literature on the card says it great for the 30" and their new 24". But no mention of another 30"
And I'm sure you would need this adapter for your best chance of getting it to work with two 30s.

XP graphics cards - will these be recognised under bootcamp?

I'm considering purchasing a MacPro quad Xeon 3.0GHz with stock 7300GT, and installing Bootcamp and subsequenty Windows XP Pro. After doing this, i intend to install an nVidia 7900GTO 512MB and run this under Windows XP....however i have 2 questions.
1 - will this work, along side the 7300GT as a 2nd graphics card and drive 2 monitors in addittion to the 2 running on the 7300??
2 - is there any possibility that the 7900GTO would function under OS X??
any replies gratefully received.

The 7900GTO will work fine in XP via BootCamp, currently Hard Drive drivers are causing bad transfer rates which result in poor performance. Soon to be fixed with new BootCamp drivers.
7300 will work in OSX and BootCamp, the 7900 will only work in XP as Apple uses its own firmware for their approved cards so it basically won't be seen. If you don't mind using the 7300 is OSX and the 7900 and 7300 in XP then it all is well.
Bare in mind the cards will work entirely separetly, not SLI'd. So you obviously use the more powerful 7900 to play games and what not on XP!

Second Graphics Card for HDTV Output + HDV Live Preview

Hi guys,
I have a few questions about hardware and Premiere Pro CS5. I am using Windows 7 x64 with a Dual DVI nVidia GeForce 7950GT which is outputting to two DVI LCD monitors. I want to install a second graphics card so I can look at the main preview window in Premiere on my HD LCD TV and would like to know what the best plan of attack is. Also, I want to be able to preview my HDV captures on my HDTV as relying on the 2.5" LCD on my Sony HVR is not eye-friendly!
I am thinking about either selling the 7950GT and buying a GeForce 470GTX which has 2 dvi and 1 mini-hdmi, or, keeping the 7950 and buying a cheapish 2nd graphics card to just use for the HDTV. What do you guys think is the best option?
This is the graphics card I am thinking of getting ( http://www.asus.com/product.aspx?P_ID=hs87bcOLPd9irXRk&templete=2 ) an ASUS ENGTX470 / 2DI / 1280 MD5, my server can just handle it's power requirements, but I am happy to upgrade the power supply if this card will ouput to 2 DVI monitors and also to a HD TV with a mini-HDMI to HDMI adapter. An Antec 1000w power supply is only about $225!
Or, I can take the cheap option and get an NVIDIA Quadro FX 580 by Leadtek( http://www.leadtek.com/eng/workstation_graphics/overview.asp?lineid=2&pronameid=491&check= f ) which is a cheapy with 2 HDMI and 1 DVI. I guess there are other PCI-X graphics cards out there to choose from which are probably fine, but it would be awesome to know what some of you guys are using.
Surely there are others out there that already have a dual monitor setup with a third LCD TV for previewing?
Anyhelp would be much appreciated!

@Harm: Thanks for that, I thought a card with three outputs would be too good to be true. I think I will buy a much cheaper 2nd PCI-X graphics card and just use its HDMI output for the HDTV. We will be doing a complete overhaul of this machine sometime in the future and I will buy an awesome graphics card with power supply to boot then.
@J-MS: Currently we are moving away from a Matrox Axio HD as their support for Windows 7 and CS5 has been lackluster, and I don't reward companies that provide zero or no support with future business. I would rather be free of a third-parties proprietary codecs, plugin and decoders.
@Thrill: Thanks for the link to that post, I read through it and it looks like I need to get a second card that is the same make as the existing card (ie. nVidia), which is what Harm was saying. When I capture from the tape deck, the capture preview window in Premiere goes blue and says in 5 different languages that the preview is going to show on the input device, or words to that effect. I am therefore looking at a 2.5" lcd for capturing! fail. I don't know why that is happening now to be honest, maybe it was because I was in a Matrox HD sequence before and the input device wasn't set correctly? I will double-check it again and see what the deal is.
I am very tempted to just get an el-cheapo nVidia 8400GS Turbo Cache 512M DDR3 DVI HDMI which is only $39!!!! It has HDMI and is small and has a very low power drain on the system. If it outputs to the HDTV then that's all I need, if it doesn't, I sell it on ebay for $25 and lose $14, big deal.
