HD 4870 x2

I did a quick search and could not find an answer so I thought I'd post.
I have an ATI HD 4870 X2 card and I was wondering if it will work with my Early 2009 Mac Pro. I saw a few posts about the 4870, but I could not find any about the 4870 X2
http://www.amd.com/us/products/desktop/graphics/ati-radeon-hd-4000/hd-4870X2/Pag es/hd-4870X2.aspx
There are no Mac drivers for this card on the ATI site, but I wanted to ask anyway.
Thanks in advance.

I think he's referring to using a Radeon 4870X2 Dual Core GPU (http://www.pugetsystems.com/blog/wp-content/uploads/2009/04/4870x2_internal.jpg), not running two normal 4870s.
If that's correct, there's a chance it would work in any Mac Pro, it just needs to have both the 32-bit and 64-bit roms like like a normal 4870. You could very likely get someone to flash it for you, the only thing is, as with CPU cores, it's up the OS to support them, which I don't think OS X does right now. I haven't done a lot of research on this, as it's pretty new, but in the end even if does work, I don't think you would see any benefit on a Mac.

Photoshop CS3 allows me to enable Open GL but CS4 does not Brand new MacPro with ATI 4870 card

Hi,
I just bought a brand new 8 core Mac Pro and have both the ATI 4870 graphics card and the Nvidia GT 120 card. Pshop CS3 allows me to "enable openGL" in the prefs and utiizes it when doing 3d stuff... however, CS4 has it dimmed in the prefs, thereby not allowing me to check it (it is dimmed and unchecked I should say) and when I do 3d stuff a dialog box saying
"Your video card does not meet the requirements for hardware-accelerated 3D rendering. All 3D will be rendered with software only."
any thoughts?
thanks in advance.

yeah, short term test deems keeping both cards in.
So, here are the results: Notes: I have 2 monitors, an Apple 30" and Apple 23". The 30" can only be used in the dual link dvi port and NOT the Mini Display port. Second: The ATI 4870 seems to have an issue with the Mini Display port, it does not work, alone or in tandem with the dual link dvi port being used. Apple is replacing the card (heretofore, I had no cause to use the Mini Display port on the 4870 at all) Third: Only Photoshop CS4 extended was used to see if the card was detected and if it had enabled Open GL
ATI 4870 - dual link used, Mini Display NOT used: Photoshop sees the card and enables Open GL
ATI 4870 - dual link used, MIni Display used: didn't test because Mini Display port did not work.
ATI 4870 - dual link NOT used, Mini Display used: didn't test because Mini Display port did not work
Nvidia GT120 - dual link used, Mini Display NOT used: Photoshop sees the card and enables Open GL
Nvidia GT120 - dual link used, Mini Display used: Photoshop does not see the card and thus Open GL is NOT enabled.
Nvidia GT120 - dual link NOT used, Mini Display used: Photoshop does see the card and Open GL is enabled
ATI 4870 Dual link used, Nvidia GT120 Mini Display used: Photoshop does not see a card and Open GL is NOT enabled.
ATI 4870 Mini Display used, Nvidia GT120 dual link used: did not test because ATI Mini Display port did not work

ATI Radeon HD 4870 1GB for Mac Pro 2.66 Quad Core Xenon

I have the option of picking up an ATI Radeon HD 4870 1 GB graphics card to go with my soon-to-be-new MAc Pro 2.66 Quad core. I see know that Apple can upgrade to ATI Radeon HD 4870 512MB, but that card is not available to me at the moment. Will the 1GB do the job without overheating the system? Am new to the Mac Pros. Need it for the Windows gaming portion of the system. Am using the rest for graphics and photography.

If the MAc Pro 2.66 comes with Snow Leopard, why would I have to upgrade my OS?
OK. So, if got the MAc version, it would work A-OK without overheating?
Thanks for your input!

How Do I use an Ati Radeon 4870 HD for 3 Monitors

I am new to the Apple world and community. I recently got a new job that requires me to use a Mac Pro. OS X version 10.6.8. 2.66 ghz dual xeon and 32 GB of ram. It has a ATI Radeon 4870 HD. I can run 2 monitors fine using the DVI and Mini DV port ( Using a convertor from apple. ). When I try to use the 2 other HDMI ports for my third monitor, Mac OS wont detect it. The wierd thing is some of the images from certain apps show on the 3rd Monitor.
Under graphics information it shows the Radeon 4870. Under PCIe information it shows the same card. On the back of my machine I have 2 HDMI slots and another lower down with Mini DV and DVI.
The Displays I am running are 3 HP LP2475w Monitors. Running in DVI mode with one converted to Mini DV. The 3rd non working is running in DVI to HDMI but it can be run Straight HDMI if need. Ive tried alot of configuration settings and I can't get the HDMI port to be detected by MAC OS. Ive plugged one in at a time and just the HDMI do not detect.
Please let me know what information is needed to help troubleshoot this better.

A 5770 is $249 or slightly less and in the same dept to me as replacing hard drives, adding some RAM in order to work and because my understanding is it was the first card to support 3 monitors.
The 5770 only requires 10.6.5+ - and the 4,1 had way too many issues with 10.5.7/10.5.8
The 4870 may or may not provide what you need for the software you run, even though 3 yr old machine but 4 yr old plus video card.

Getting Asus ATI 4870 to work in my Mac Pro. Not working. please help!

I read here on these boards that an ATI 4870 would work in an early model (in my case, 2006) Intel Mac Pro.
I jumped in hastily and bought the Asus branded card: EAH4870
I connected it, and nothing... did not work.
I do not think it is a Mac version of this card, perhaps intended to be used in a windows machine.
Questions:
- Do I need to "flash: this card to make it work in my Mac Pro OSX 10.6.3?
- Are there Mac drivers for this card? I can't find anything anywhere
- Basically, can I get this card to work, or do I need to PAY the extra $$$$ just to have a "Mac" version of this.
Keep in mind, I am not a techie, I need to do Work, not fiddle with this kind of stuff.. unfortunately, a software package crucial for a job is very finicky and works with only a handful of cards.. The 4870 is one of them.
I do not have dual boot, and no windows machines to "flash" or rework this card.
If you can help me to get this card to work, it would be MOST appreciated!!!

It is not a Mac version. It does not have the required EFI boot ROM needed to work on the Mac. Video drivers are contained in OS X. Either you have to have the card flashed (this is illegal) or buy a Mac version of the card.
If you aren't a "techie" then you don't have the hardware needed to flash the ROM nor know how. Because this site belongs to Apple we cannot help you with something that is illegal.

ATI Radeon HD 4870 Composite Video?

ATI's spec sheet on the Radeon HD 4870 states that it can provide an analog composite video out. Is this feature enabled on the version that can be optioned on the Mac Pro, and if so with what adapters?

Early 2008 Mac Pro + ATI Radeon HD 4870 = Not working

Just took delivery of my new HD 4870 video card today. I installed it in my Early 2008 Mac Pro and booted up. I got a picture no problem on one monitor, but nothing on the other. Furthermore, the display perfpane was missing a lot of controls, like Arrangement and Detect Displays and whatnot.
I did a bunch of rebooting and swapping of cables, and determined that both the mini-display port and the standard DVI connection will drive a monitor. However, if both are plugged in, the only active display is the one plugged into the mini-display port, and there's no option to setup the secondary display.
So I booted into bootcamp, and it automatically recognized both display ports, and mirrored my desktop on both monitors. I downloaded and installed the latest windows drivers, rebooted the machine into windows once more, and was able to configure a multiple monitor display with no problem.
This tells me it's not the card and it's not the motherboard.
Booting back into mac OS, I discovered that it doesn't even recognize that the card has video ram. It thought I had no video ram in the system.
So, this all leads me to the conclusion that Apple shipped me a card that it has not yet provided driver support for.
Hey Apple, can I have my 4870 display driver now?

Hi again,
It was funny to read all your answers on my iPhone while away from my computer. I could have reply on the iPhone but I preferred to wait to give you all the procedure I used to install the beta driver successfully this morning.
To start, I found this link:
http://www.insanelymac.com/forum/index.php?showtopic=155477
and followed the "4870 INSTRUCTIONS", starting like suggested by doing the "First, follow the 4850 INSTRUCTIONS above"... (See the link)
I would like also to specify that I did this without having installed the card physically yet. So I kept my HD 2600 in the computer, followed all the steps excepted for the step 3:
3. Reboot with -f -v (kextcache/verbose mode)
There is no -f nor -v switches available for the reboot command at the shell prompt. I simply rebooted as usual "Pomme -> Redémarrer".
After the reboot, all my software was still working as expected with my HD 2600 card, meaning that these steps are specific and active only for the HD 4870 when it's detected at boot-up.
You may have to Google for the string "Kext" in order to get the application to install the file ATY_Motmot.kext. For your information, ATY_Motmot filename is the same string as the one found under "System Information ->PCI cards" under "Name".
I get:
ATI Radeon HD 4870:
Name: ATY, Motmot
The article is not clear regarding where to find the OpenGL.framework to backup before installing the downloaded one. I found mine under:
/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/OpenGL.framework
After having shutdown the computer, just after the reboot that proofed everything was ok, I removed the original HD 2600 card and put back the new HD 4870 and boot up...
Then I check the "System Information" and found both "Quartz Extreme" and "Core image" supported!
I launched Aperture, got it!
I launched Final Cut Express, got it!
I launched Starry Night Pro Plus, got it! Then I checked the OpenGL settings in Starry Night Pro PLus and activated both options:
Use shaders where available
Use AllSky shader (Not compatible with all hardware)
When I was doing these actions with my original HD 2600 card, the software was giving me a warning that my hardware did not support these options and that it could crash.
This time, with the HD 4870, it accepted my settings and give me back a very beautiful blue sky with much more shades!
So in conclusion, it works very smoothtly with my system and I am writing this with two monitors, having bought the MiniDP to DVI adapter this afternoon
I am happy!
P.S.: A girl from Apple support called me back this afternoon regarding my problem. She was very happy two when I told her that I did apply the beta driver and that it was working very well...
Good luck and best regards...

Mac Pro 2008 with Radeon 4870 video useable resolution on DVI limited to size of minidisplay port VGA when displays are mirrored. Did not have this problem until I plugged in new monitor (miniDisplayport), but now it affects even going back original mon

Have been using the Mac Pro since 2008. Changed to a Radeon 4870 card early this year. Everything was fine.
Running an old KDS monitor from minidisplay port to VGA and a 1400x1050 projector from DVI out. Have used the
two mirrored the entire time with no trouble.
The old kDS monitor looked like it was starting to go bad so I got another monitor. Don't have much room
so it's a 14inchwith widescreen 1328x768 display. Hooked that to minidisplay port as it only has a VGA input.
Immediately the LCD display took over and restricted the output to the projector.
If I turn off mirroring, I can get projector back to normal. But this makes running programs a lot more difficult.
It worked fine with mirroring on before the monitor change. Except going back to old monitor,
now it is affecting things. I pull up display preferences. If the displays are mirrored, even setting the projector
to 1400x1050, it says "usuable resolution 1280x1024." It didn't use to do this at all.
Tried reseting NVRAM - no result.
Any suggestions would be helpful. Just looking at the image on the projector, I don't see any difference from
before.

UPDATE:
As noted in the first post, both of these newer USB DAC work fine at 24/96 on my wife's iMac, so it's clear that they didn't both become defective when I connected them to the Macbook Pro at the same time.
Resetting the Macbook Pro PRAM didn't help, so I removed the hard shell laptop case to get to the battery and remove it, then reset the SMC. After that I could use the original DAC at 24/96 again, but only IF it was plugged into the rear USB port. If I plugged it into the front USB port then the sound was garbled and filled with noise. This was a vast improvement over no sound at all.
Then I switched to the replacement/updated DAC, but I got no sound at all from either USB port at any bit-rate. And returning to the original DAC again now results in no sound again.
Sigh... I will reset the PRAM and SMC again, and see how far I can get with this. I'd still love some help. Thanks!

The ATI-X1900 works like a champ, when I remove it an install the Diamond ATI-4870 (MAC VERSION) in and connect the two power blocks on the motherboard, the system beeps like it is booting, but I do not get any output from the ATI-4870 card. The 4870's fan is running and it sounds like the system is booting, but it never displays anything.
Any Ideas ??

Can I add a second ATI 4870 to my 2009 Mac Pro?

1. Can I add a second ATI 4870 to my 2009 Mac Pro? Sorry if posted already, I searched and Googled and could not find it.
2. What is the general consensus on the EVGA GTX285? Will this out perform the 4870?
I read somewhere that the ATI needs additional power from the power supply and the GTX does not? Is this true? If this is the case are there extra power supply connectors for an additional 4870 (hence my first question).
The GTX has dual DVI out connector and this is my preferred solution to get 2 x 30" Cinema Displays.
Thanks in advance,
MIke

No. Each ATI 4870 needs two auxiliary power connectors. There are only two in the Mac Pro.
I read somewhere that the ATI needs additional power from the power supply and the GTX does not? Is this true?
No. Both use two per card.

You can use an adapter to connect a second 30" to the Mini DisplayPort
<http://store.apple.com/us/product/MB571Z/A?fnode=MTY1NDA5OQ&mco=MjkyNjI0Mg>
(The latest adapters have new firmware, and shouldn't have problems.)
If you only need two displays, stick with one graphics card.

Can I install TWO HD 4870 cards in my Mac Pro?

Please can you help?
I've just bought an 8-core 2.66 Mac Pro and two Radeon HD 4870 graphics cards, but each card requires two power cables to connect to the logic board, which has only two connectors. Does anyone know where the two cables to the second card should go? The second card works fine, but I expect the cables are for the cooling fans, so I don't want to fry the second card!

It's just that I have bought two new Apple LED displays (with Mini-DVI connectors), and of course there's only one Mini-DVI port on the HD 4870, hence the reason why I bought two cards. I can't find a Mini-DVI to DVI adaptor anywhere for the second port on the same card,
You need a DVI to Mini DisplayPort converter. There are a couple available now:

<http://www.gefen.com/kvm/dproduct.jsp?prod_id=8913>
does the GT120 also require a power supply from the logic board?
No.

Boot Camp, Vista Ultimate x64 SP1, 2009 Mac Pro Quad 2.93, ATI 4870 HD

Hello All,
I’ve run into a problem installing Boot Camp with Vista Ultimate x64 SP1 on my early 2009 Mac Pro Quad 2.93 with Apple’s ATI Radeon 4870 HD (the one with one DVI and one mini-display). I followed the instructions from the Boot Camp Installation and Setup Guide, and everything was going great until I hit page 12 of the Guide (Step 3). The Boot Camp drivers installed without error, and prompted me to reboot. Upon rebooting onto the newly installed Vista x64 partition, the screen went black after the chkdsk screen appeared. I can boot into Vista safe mode, but booting into Vista normally results in the black screen. On a hunch, while in safe mode, I uninstalled the ATI video drivers installed by Boot Camp. I was then able to boot Vista normally, but only with the standard VGA adapter. Then I tried installing the latest 9.4 ATI drivers from the chipset vendor, AMD, http://game.amd.com/us-en/drivers_catalyst.aspx. Booting normally after the ATI chipset drivers were installed left me with a mostly black screen, and a few swizzles of horizontal color, but not enough to make out any sort of image. Once again, I was able to boot normally by first booting into safe mode and then uninstalling the ATI driver, leaving me with the standard VGA driver.
The displays I have tried so far are 1) Apple Cinema HD 23”, and 2) Apple Cinema 20”. Also, I have tried all 6 permutations with the ports on the Apple version of the ATI Radeon 4870 HD with both displays (using the mini-display to DVI adapter), 2 permutations with both displays, and 4 permutations with single displays. All permutations result in the same black screen after installing Boot Camp drivers.
Am I missing something? It seems to me that there is a display driver that needs to come from Apple that will work with the Apple version of the ATI Radeon 4870 HD in Vista Ultimate x64 SP1 attached to an Apple display. I’ve installed Vista Ultimate x64 SP1 and many other operating systems in the past 27 years of working with computers, and typically with video cards I’ve had to get the drivers from the vendor that shipped the card, not the chipset vendor. Sure, occasionally the opposite is true, and I don’t mind spending a few days to figure out what works best for me as long as I believe I am making progress.
Has anyone else run into this problem with his or her early 2009 Mac Pro Quad 2.93 with Apple’s ATI Radeon 4870 HD? I’m posting this in the Boot Camp forum as I think this problem is rooted in the Boot Camp drivers, specifically for the Apple ATI Radeon 4870 HD. Please let me know if I should post elsewhere.

You are the second person I think I've seen with trouble using Mac Pro and ATI drivers (other was on Mac Pro forum).
When updating graphics, there are extra steps that insure you get the best working drivers.
I've always found Apple to be behind the curve on Windows support. Drivers that come with a card from the vendor ususally means ATI or Nvidia, and even then, you go to the web and download and install the latest tested / beta / qualified drivers. Some people try a variety of driver versions to find the one that works best.
Apple has not been updating Boot Camp drivers for Late 2008 and on Macs. Boot Camp 2.1 is now over a year old. What is on your OEM Leopard DVD is the only drivers I would use - if at all! try without is what some do, and then see if you can selectively install. Under Windows 7, I don't need or install, and now with the RC/7077 version of 7, Microsoft 'blocks' installing Apple Boot Camp drivers as known to cause problems.
If it ain't broke, don't fix it. Unistall the various Apple services, drivers, startup items that you can live without or until you narrow it down. iTunes 8.1+ in Windows can break and prevent ability to even use optical drives and devices for instance.
Some tips for upgrading drivers, one from eVGA forum but should translate.

Upgraded to ATI 4870 on Mac Pro and cant enter Boot Camp

Hi!
I have just received the ATI Radeon 4870 for my Mac Pro (Early 2008)and have upgraded my Leopard to 10.5.7 and works fine on the Mac side. When I reboot and hold the command key I can see my MAC and my BOOT CAMP 2 options as always before. When I click on boot camp I get a white screen with a black frome around it and there is NO hard disk activity and nothing happens no matter how long I leave the computer alone. Before I had no problem booting into my boot camp loaded with vista 64 bit. I have another partition with parallels and that is fine but not this boot camp partition.
Any suggestions?
Thanks for all your time!

I guess you can't boot Safe Mode.
I would have uninstalled the graphics drivers first, as part of preparing to swap cards. Assume you had.... before this and the proper ATI (or Nvidia) drivers. Put back in the original card.... or are you trying to use both? Again, not clear from your comments.
You can't use ATI and Nvidia in Windows concurrently, don't know why but seems to be rule that they won't be compatible.
You have another - physical - native Windows partition? or a Parallels VM that is not using a native (Boot Camp) partition, which works.

ATI 4870 AND NVIDIA GeForce 7300 GT together ?

hello. i have a mac pro 1.1 with the stock NVIDIA GeForce 7300 GT video card. I will receive a new ATI Radeon HD 4870 card today and was wondering if it was possible to have both cards installed and if this wold provide a performance boost (ie will rendering videos utilize the power of both combined etc) . Also, i would like the option of having 3 displays . So 2 questions,
1. can i have both cards installed at once?
2. and if yes, will it provide benefits or problems/conflicts ?
thanks
Mac Pro 1,1 , 5GB Ram , Latest Snow Leopard , Mac 20ish" Display, and Sony Bravia 52" as display using dvi-hdmi cable .

I've run the 4870 together with the 7300gt; there were no problems whatsoever. You'll be able to run 4 monitors, other than that there are no other benefits. This is under OSX.
Note though, if you're running windows under bootcamp, with both cards installed you will likely run into driver conflicts. Best to keep to the same "clan" (ATI or Nvidia) when booting in windows.

ATI Radeon 4870 won't detect second display

You can't use more than one converter per display.
You need to get single converter that connects directly from the Mac port to the display.

ATI 4870 DVI-VGA not working. Help?

Howdy folks,
I was using an ATI 4870 with two DVI ports and one S-Video port on a Mac Pro 3,1 (I think) running osx 10.5 with two monitors
When we retired that computer I harvested the 4870 card to replace a GT 120 on a Mac Pro 4,1 running osx 10.8. It has been feeding two monitors without issue, one DVI and the other DVI-HDMI.
However, I cannot seem to get it to recognize any VGA monitor or projector using any of three different connectors. Nor can I seem to get any signal out of the S-Video port.
My goal is to run a VGA projector with the Mac Pro 4,1, a projector with VGA, S-Video, and RCA inputs.
As I said, I have tried three different DVI to VGA connectors. Two of these are very similar with 29 pins on the DVI connector. These did absolutely nothing. The third has only 17 pins, and while it had no result with projector, when connected to a VGA monitor the computer would recognize that a second monitor was attached, but no signal seemed to be carried to that monitor. The osx settings showed options for two monitors, but no image appeared on that second monitor.
One of the two DVI to VGA connectors I had successfully used on the previous Mac Pro 3,1 computer, but I cannot remember if it was with the 4870 or the graphics card we used before upgrading.
A Macbook using a MiniDVI to VGA connector feeds a signal to the projector without issue.
If this community can offer any help or guidance, I would be very grateful.
Best wishes-

The signals used for VGA are generated directly by the DVIO-I port on the graphics card, and are supplied in the bar at the right end, the four pins around it, and one pin from the top row of the grid (salmon/pink in the diagram above). A VGA adapter has no active components in it -- it just picks up those five signals and presents them on the proper VGA pins. The bar is used as the common return.
A failure is to produce a signal is not likely to be a failure in the adapter, but a failure on the graphics card.
DVI-I (Digital AND Analog) has the bar and the four pins around it present.
DVI-D (Digital only) has no bar, and the pins around it are not populated.
