Dual GPU, ATI + NVidia. Is it possible?

Hello. I work with CUDA in the college and now i am kidding around with pyrit. And i have seen that ATI cards outperform the nvidia ones, with a lower price. So, is possible to use an ATI card with a NVIDIA card? The main card(the one that will provide video) will probably be the nvidia or the onboard, since when computing with cuda the video keeps freezing.
My motherboard is a z77m-d3h and my gpu is a msi gtx 660 ti. The mobo has 2 PCI-E slots.
Will be any problem with drivers?
I also want to start using openCL with and ATI card. But i dont want to buy another computer or to physically change which card i will be using. So i need both ATI and NVidia cards on the same computer.
Thanks..

carneiro :
try opencl-nvidia / opencl-nividia-304xx , looking at their dependencies it should be possible to run them without having the nvidia video driver installed.
granada :
check https://wiki.archlinux.org/index.php/Opencl
amd opencl solution currently requires catalyst to be present.
The gallium compute solution for the open source radeon driver requires a custom build of mesa.
(if you want to try this one, check lordheavy's mesa-git repo. some details about using opencl with that repo :https://bbs.archlinux.org/viewtopic.php?id=170468 )
I very much doubt the combination of nvidia video driver and catalyst or xf86-video-ati will work though.

Laptop intel 4000 gpu and nvidia 675m offer same performance?

in photoshop...particularly when rendering 3d extrusions they both do the same time rendering a layer. obviously i can force photoshop to use either gpu. the 675m is a heck of a lot more powerful than the integrated intel gpu.
any special trick to make it render faster using the nvidia as opposed to the intel?

The concept of a dual GPU laptop is that the embedded Intel GPU will come into play, when you are on the battery, doing very low-level and general computing, and it will save battery life.
In a perfect world, when using higher-intensity programs, such as Ps, the nVidia, or AMD/ATI GPU will automatically come into play, giving you greater performance. That is not always the case, but is what is intended.
With a program, such as Ps, you will not be using both GPU's for any process - it's one, or the other.
Good luck,

CC & Dual GPU

My new build is running a GTX570oc , I can pickup a 660ti for $200 to add.
I know sli was unsupported a while back, but what's the workings of CC and its dual GPU support ?
Will it utilize both cards and unlike sli doesn't matter if they are a matching pair ?
The 660 has 2.5 times the cuda cores at a fraction slower bandwidth so I think ill get some good results.
Does dual GPU in CC require much setup/tinkering and does it just use both, or make a primary and secondary ?
Thanks
Troy

Troy,
Dual GPU in CC is trivial to set up and requires no tinkering for the additional card. Of course, this assumes that you have enough power supply, PCIex16 slots, MPE hack, and cooling for the additional card(s). You do not need to SLI the cards to get the benefits in Premiere Pro. I did read on this forum that it works with mis-matched GPUs, but I've only seen that verified for cards using a common driver. As you probably know, the two cards that you mention do share a common driver from nVidia.
You need to ask yourself why are you doing this though? For most rigs, I would expect that with a single decent GTX video card already in place that the only speed gain would be for DVD renders. For most other work flows, other items in the PC would be the limiting resource (CPU power, drive speed, etc.). On the other hand, if you are constantly doing DVD exports for high-def media, then the increased number of cuda cores will make your world so much better.
See the following post regarding for my test results on a dual GTX Titan setup where adding a second video card doubled DVD exports, but left pretty much all others performance areas completely unchanged:

Dual GPU's

Is Aperture able to leverage any advantage from dual GPU's?

Is Aperture able to leverage any advantage from dual
GPU's?
I think Aperture would beenfit to some extent, because while CoreImage is using the GPU's so is the rest of the system. Also possibly it could split CoreImage work across both GPU's, do not know enough details about how Core Image uses the video cards to say for sure.
A stronger video card is always going to help out Aperture to some degree though.

ATI & NVIDIA

Hey everyone, I originally posed this question about a month ago and got mixed results. But now that the Mac Pro has been out for a good month+ maybe someone has found a definate result. I am looking to use 4 monitors; 2 crts, 1 regular lcd screen that needs to be rotated, and 1 hd lcd. I currently have the standard Nvidia 7300GT and was wondering if I could shift that to the second pci slot and put in an ATI X1900 XT in the first spot. I am concerned with three things. First, if Mac will have any driver issues or conflicts that will prevent 4 simultanious monitors from two seperate brand graphic cards. Secondly, (the same as the first) but under Windows XP (x64), and finally if there will be any problems rotating the canvas of one monitor.
Any insight would be great. Thanks

Hi,
First off, I too found little information about multiple monitor setups on the Mac Pro. I have a triple monitor setup (ati + nvidia) and posted some of my comments here: http://discussions.apple.com/thread.jspa?threadID=646226&start=0&tstart=0
I have not been able to get the nvidia card to work along with the ati card in windows. I can use the 2 monitors hooked up to the ati card, but not the monitor connected to the nvidia card in windows. This means that I can use windows, it just won't work with monitors hooked up to the nvidia card. If anyone has got this working please post!
Also, I am using Dell LCDs, while another poster in the above mentioned thread using Apple LCDs said he could not get Windows to run properly (resolution issue). I have not tested portrait mode, but don't think it would be a problem.
I am not currently a Final Cut user, so I cannot comment on those questions but otherwise the 3 monitors work OK on the OS X side. I have only worked with 2d apps and have not had any real issues. I was able to run 3 720p HD videos concurrently (1 in each monitor) with no stuttering.
Regarding spanning, if your app is really GPU intensive, it would be best to span across the 2 monitors connected to the ati card.

You can try using Screen Sharing in the Sharing preferences. Or try a third-party utility such as ScreenRecycler.

Dual monitors on nvidia geforce fx 5200

Hi,
I'm using a nvidia geforce fx 5200 card that has vga out, dvi out, and svideo out. I have one crt hooked into the vga, the main monitor, and I have a dvi to vga converter, to enable a second vga, crt monitor. When I try to use the nvidia-settings, and enable twinview, and I get this message:
"failed to set metamode (1) 'CRT00: nvidia-auto-select @1024x768 + 1024+0, DFP-0: 1024x768 @1024x768 +0+0' (Mode 2048x768, id: 50) on X screen 0."
any ideas? thanks.

Hm, Not working, just display on the true vga monitor. Are you using a dvi to vga connector as well? Heres my log output, I couldn't make too much of it, I tried to switch the CRT-1 to DFP-0 which didn't seem to do the trick either.

Dual-head on NVIDIA

Hello, I'm trying to configure a dual-head setup (NVIDIA proprietary drivers). I've tried both Xinerama and Twinview, but the screen is always treated as one big virtual screen and window managers spread fullscreen windows over both monitors.
Here's what I've tried (they all resulted in the above):
- # nvidia-xconfig
- These instructions
- # nvidia-xsettings
- These instructions (I might've misunderstood them, they were fairly vague)
In addition, Xinerama seems to disable the randr extension, which makes me unable to use xrandr or arandr, so the preferred option is to use Twinview.
For clearance, when I open arandr, I see one big, wide screen called default. How do I set it up so that it shows 2 different screens?

Separate X sessions on dual screens (both monitors have own x sessions )
no xrandr
only

Dual Xeons Or Dual GPU Premiere cs6?

Hey,

Iam willing to upgrade to dual Xeons like " HD-Juggernaut"
from ADK.
Is it helful for PR or not, or i just stick with i7?

As Bill said, dual GPU is not a good idea... some previous discussions

Graphics Error AMD Radeon HD 7640G/7670M Dual GPU

HI,
I am facing a problem with my HP Pavilion g6-2301ax Notebook PC with AMD Radeon HD 7640G/7670M Dual GPU (2 GB DDR3 dedicated) with Windows 8 64-bit. I haven't made any changes to the hardware/software nor have I connected any new hardwares.
I cannot watch Videos no matter what program I use, be it VLC, Media Player, etc. The programs simply crashes. It takes quite a considerable time to boot and Restart/Shut-Down, than before. Here's a screenshot of the error message...
Also, the AMD Catalyst Control Centre keeps crashing...
Before, the Graphics Control Interface was totally different. The so called "Hydra Grid" wasn't there. The Control Menu had more options and the ability to customise. Since, it is a Dual GPU, there was an option whether to choose both or just one. This problem started like 2-3 days back.
I am really really frustrated. Because of this, my work is getting hampered a lot. Also, it doesn't read an external Hard Drive which has USB 3.0, even though the "safely remove icon" is shown at the task bar. And now, because of this I can't even Back-up my files on to the external hard drive in order to Recover or Restore it to Factory Settings.
Somebody help me.
Warm Regards,
Zamyang.

Hi @cheemsay ,
Welcome to the HP Forums!
It is a dynamite place to find answers and ideas!
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I understand that you are unable to play videos regardless of what player you try. You have not made any physical changes to your notebook or added any external hardware.
When you connected your External drive you get the safely remove icon but does not install the drive.
If you look in device manager does the external drive have any bangs or error on it. Have you checked the manufacturers site for a driver for it?
If you check disk management does it have a drive letter assigned to it?
Here is a link to
Testing for Hardware Failures (Windows 8) that may to determine the cause.
You state this happened only 2 -3 days ago and you cannot do a restore as the external is not being seen correctly but you should be able to do a recovery back to factory.
Do you know in updates were automatically installed?
Here is a link to Performing an HP system recovery (Windows 8) that will guide you through the recovery process.
I hope this helps!

Can I run CC on Intel Pentium G2030 3.00GHz dual core. NVIDIA Geforce GT610 1GB graphics. Viglen Vig642M Motherboard?

Can I run CC on Intel Pentium G2030 3.00GHz dual core. NVIDIA Geforce GT610 1GB graphics. Viglen Vig642M Motherboard?
I also have 8GB RAM DDR3, 1TB HDD, Its on Windows 7, is that a problem with the allocated graphics card?

Thanks John,
I've done this, but couldn't gather clear information about whether the graphics card was suitable for Premiere CC? Using CPUbenchmark it seemed to me like it would be suitable. Its unlikely we would use After Effects CC but would be handy if it would work.
Also the G2030 dual core? Can you recommend how I find out if this would work, as the site states the requirement to be a Dual Core2... does this mean the software (Premiere CC, Photoshop CC, Indesign CC etc) would not work at all?
Any guidance helpful.

Cannot use GPU acceleration with 64 bit CS5 under 64 bit Windows 7 with two cards ATI & nVidia

Subject sums up the problem, but here are the details:
My ATI is a 5850, and I have drivers 10.6 installed. That's my primary card connected to my main monitor.
The second card is an nVidia GTS 250 connected to my second monitor with 258.96 drivers.
CS5 does not detect my GPU(s), hence, does not enable GPU acceleration. It says:
"Graphics hardware acceleration is unavailable. You will need to upgrade your video driver and possibly your video card" both of which are obviously wrong, since I have the latest CS5 supporting drivers installed for two cards that can run GPGPU applications!
Any suggestions?
Thank you.

I'm curious about whether the requirement to support HLSL Shader Model 3.0 is a big part of what is holding back GPU acceleration support for ATI cards in Adobe products. It seems that HLSL Shader Model 3.0 is NVidia/Intel proprietary, whereas GLSL is an open standard like OpenGL.
What ATI support do you find being held back? Just curious. I ask because I have a 2 year old ATI 4670 card that supports Photoshop nicely. The Catalyst software seems to have embraced whatever's necessary to run Photoshop.*

* That said, I see a specific bug where sometimes the 32 bit drivers on my x64 system will not be recognized by Photoshop 32 bit as OpenGL-capable at Photoshop startup. I've reported it to ATI, and they seem to have taken it seriously, so I expect a fix in a future version. The 64 bit drivers always satisfy Photoshop's needs, so I'm sure it's not a design deficiency but just a lil' ol' bug.

Acer V5 753g (Intel Haswell / Nvidia GT 750m dual GPU) Bumblebee

I think I am fighting several issues here, altough I might have fixed one already. Up to this point I managed to disable the nvidia gpu, using the proprietary driver and bbswitch, but bumblebee is not working.
Okay first, I could isolated an issue with acpi, by following instructions in this bug report https://github.com/Bumblebee-Project/Bu … issues/460. To be exact it made me install a kernel module, code and install instrutions are described here: https://github.com/Bumblebee-Project/bb … ack-lenovo (After the bug report the author of this code was generous enough to add my model to the source code, so midifications weren't neccesary any more).
Now after a reboot the gpu is disabled, but as soon as I run optirun (which fails) I am not able to disable it again
I know the exact same issue is discribed in the bumblebee arch wiki page, but none of the workarounds fit my situation.

Your issue seems to be similar to what I had to face with the Razer Blade 14" (similar hardware as well).
Goto: https://bbs.archlinux.org/viewtopic.php?id=173356 and see the instructions to get graphics to work, see if it applies (summarized: run linux-ck and set rcutree.rcu_idle_gp_delay=2 in the kernel parameters).
I haven't tried undoing this in more recent updates because I haven't had the time to mess with it---it is possible that it has been fixed, although the thread following my and possibly your issue at nvidia doesn't give any indication of that:

ATI X800 XT 512MB on MDD dual boot dual 1.25Ghz.... possible?

Hi,
Just looking to see if I can install a Mac version of the ATI X800 XT 512MB on G4 MDD dual boot dual 1.25Ghz machine?
If so... great... I'll go pick it up straight away.
thanks
PS. I know it won't accelerate 9.2.2, but I already have the 9200 PCI card to accomodate that.

Just following up on japamac's excellent response.
ADC presents a seriously limitation on cards since the only two retail cards (no flashing, no fuss) on the market are the ATI 9600 and 9800, both without ADC.
I use a modified 9600 Pro from a G5, which has an unpowered ADC. Unpowered because the the ADC tab doesn't align, although some people have modified the card further to get power to the ADC port. For info on both of those mods, see:
http://www.pistolerapost2.com/viewing/96002g4.html
There is one last card -- extremely -- I can think of with ADC and more oomph than the retail 9600: the Apple OEM 9700. That was a BTO option for the MDD. Here's some info on that card:
http://www.xlr8yourmac.com/Graphics/Radeon9700PROOEM/index.html
Again it's really rare because it wasn't available even as a BTO option for very long. They fetch a premium on the used market when you find them.
What ADC monitor do you have? I hope an LCD. In which case, something to consider is the Apple ADC-DVI adapter which will set you back $100. It's basically a kind of splitter, with a brink supplying power to ADC monitor while passing the signal from the DVI port. Yeah this adds to your costs, but gives you more options in terms of cards.
Oh more thing about 9.x acceleration which you mentioned. With ATI cards, you might need to pull an extension or library from the Extensions folder to keep 9.x from stalling at boot. I had to do that with my 9600. Sorry, I'm on my MBP now, so I can't tell you which ones. Let me know if you need/want to know which ones I pulled.

Is a dual monitor setup with 2graphic cards possible?

HI.
What i want to do is run Archlinux on my Desktop but i dont want to miss my second monitor.
I could use both monitor on my nvidia graphiccard but i want to use the energy saving features too (wich dont work with 2monitor on one card) therefore my windows setup is big monitor on nvidia and the smaller one on the intel onboard card.
They both get recognized by lspci but only the onboard cards isy being used (the onboard card is the first card on windows too).
So is it possible to get it to work? Id really want to use ARchlinux on my Desktop too but i dont want to use it with one screen or without energy saving?
Working compositing is a must, i want to use gnome3 wich is the only reason to swich to linux for the Desktop (arch is running on the laptop for ages^^) but i dont need to, Win7 is working flawlessly fine and i didnt have to pay for it (msdnaa).
Thanks in advance!

hy do you need to clock down your card?
Most gpu have a function that clocks down the card@idle and or desktop.
In my case thats down from 850mhz(560ti)to 200mhz while using windows and 50mhz if the gpu load is low.
Thats about 20watts less then with full clock.
The problem is, that the gpu wont clock down with 2monitors on it, it stays at 850mhz.
Theres some driver tweaks for amd cards wich "fix" thatfix this (i believe its intentionl, 2monitors equals more load but its no problem with new cards...
Thats one reason i use my onboard gpu for the second monitor, it works well with windows and also means that swiching off fullscreen (games) to the desktop works a lot better, the second monitor can play a movie while playing wich doesnt work with one gpu and fullscreen.
I really dont need that with Linux since i use it for work and multimedia only but the energy saving feature is nice if the pc is on 8hours and more wich is often the case.
Can you tell which one do you run? I'm going to buy one for dual-monitor setup, and I'm looking for something that will work for shure.
As said dual monitor on one gpu works, amd can do 3monitors while nvidia can do 2 at once, that means if u intend to use 3monitors some day with ur card u have to buy an amd card.
i took the nvidia because is can use it to render videos with cuda support (its not working with all tools yet but its getting better and if it works its a lot faster then my cpu rendering).
PS: Thats one hread about the power saviing with 2monitors:http://forums.nvidia.com/index.php?showtopic=197557
since my monitors dont share the same resolution it seems that theres no way to make it work .
