Mac Pro :: Installed 2 Of The ATI Radeon 3870?
Mar 13, 2009
has anyone installed 2 of the ATI Radeon 3870 (mac edition) cards and get crossfire mode to work successfully in XP under bootcamp? I've been trying to for a few days now with no luck!
The drivers for bootcamp on ATI's site won't install on my machine for some reason and when I use the normal xp drivers (successfully) I can't get the crossfire option to show up in catalyst control center.
Also, in the catalyst control center, it only shows the primary card as enabled and says my other is disabled. However, they are both enabled and working just fine according to the device manager.
Cards are installed in 1st and 2nd slot.

I'm using OS 10.4.11 on a first gen mac pro. Would I have to upgrade my OS or will this card work on it. If the card is not compatible with my OS what cards would be besides the ATI Radeon x1900.

two U2311's from Dell to add to my 30"ACD for a three display set up. I placed the order without putting much thought into how I'm going to drive the 3rd monitor. I have a 2006 MP 1,1 with an ATI 3870 installed. I still have the X1900 that came with the MP but its not presently in the MP. I think that it still works but as I remember its kind of loud. So what are my options for running 3 monitors. I'm just looking for increased desk space not any kind of gaming set up like is possible with the newer ATI cards. From what I've read so far my options are3870 / X1900 - cheapest solution but probably not the best solution

Has anyone tested this scenario? Since PC versions of the 3870 are cheaper than the PC+Mac version, I was wondering if I'd be able to crossfire the PC+Mac version, and a regular PC version. (Obviously I'd only be looking to run Crossfire on the Windows side.) Would this setup cause problems with either the OS X or Windows side? BTW, I've got the 2008 Mac Pro with 2 PCI-E x16 slots.

I bought the PC version of the ATI Radeon HD 4870 and flashed it with the mac ROM. Everything went fine. I then moved the original card to slot 2 and put the new ATI card into slot one. I connected the monitor to the new ATI card and booted up. I get the apple logo, but after that, my monitor loses signal. If i plug the monitor into the original card (which is now in slot 2), it works fine. The desktop shows up. Any ideas on what is going on here? Is there anyway to check what hardware is installed in the computer? Any utilities?

I need to get component video out (HDTV) and am trying to get a video card that can do that. This is for a Quad 2.66 Mac Pro, currently with a 7300GT. Is the HD 3870 it? Since it's a Mac & PC edition and the PC cards have had Component Out via adapter for some time, I am hoping that this card might do it. Naturally I don't want to buy just to find out it isn't. Their website is useless, as usual.

I dont know how to describe it but like the macbook rev. a's it has a faint mooing noise. Its not loud or anything but when your in a dead silent room you can hear the silent revving up and down gently of the fan of the ati 3870.
Kind of like a mooing sound but a bit higher pitched than what the macbooks sounded like I guess. It is only apparent in dead silent room and when your playing something intensive like a 1080p movie other wise during normal usage the card is dead silent.

Anybody running the 3870 under Bootcamp with XP? Which drivers are you using? Windows is complaining the drivers don't exist for the card even though I installed them from the CD.
Nevermind, I finally got it worked out. It took a couple of reinstalls of the software. I don't know why. I am clueless on Windows.

I just reinstalled leopard to try and deal with some aperture slowdown issues (long story). Since I no longer have my x1900 in place I just installed with the 3870 running. I have only single monitor support out of the box. It would appear I -have- to install the ATI driver disk. So I'm thinking I'll just check on the ATI site to make sure there is no updated/newer driver. THERE IS NO DRIVER ON THE ENTIRE SITE! WTF. I went through the mac section - no drivers, just pitiful card info. I went into the driver section - nothing other than 10.4 drivers. Why in the world are there no drivers for this product available for download? Is that just to keep people from flashing a stock card? I guess I'll install my old disk, but this was very irritating.

I have a Mac Pro and the stock 2600 installed. Having waited for months on my preorder of the Radeon 3870, its still not in stock, and its been delayed for another 3 weeks in the UK. I have a couple of questions, Is it possible to flash the PC 3870 card to work in OS X? I�ve had a quick search on this forum, and I�m unsure as to what the results conclude. What is the highest performance mainstream graphics card that can run on the Mac Pro, officially or unofficially? I need the card by this weekend.

Can anyone who is using this card let me know if they have had issues with CS4. I'm trying to determine if this related to the video card.
Problem: When I try to view a slide show or do a full screen view all I get is a grey screen, pictures do not display. The Radeon HD3870 Mac & PC edition meets Adobe's specs for Photoshop and Bridge CS4. Adobe has tested the 3870 with Windows but not with OS X.
Adobe's documentation lists Bridges GPU functions as
Preview Panel
Full-screen preview
Slideshow
Review Mode
Only the Preview Panel is working correctly.
Here are my system specs:
MacPro 2 dual-core processors 2.66 GHz
5 GB of certified memory
ATI Radeon HD 3870 Mac and Windows edition
the vidio card has 512 MB of VRAM
I'm running OS X 10.5.5
The driver that is installed is the original from the disk. I could not find an updated driver on ATI's site or Apples site.
My system info shows two listings for the HD 3870, both in slot 1. The first has display for type and yes for driver installed. The second lists ATY, MegaledonParent as type and no for driver installed.

I just installed the graphic card and when I turn on my Mac I get the Apple Logo and the spinning progress wheel and then the screen turns blue for 5 mins and then turns on. The tech at OWC said that it is normal to do that the first time but should speed up after the subsequent restarts, etc. Well, it is continuing to take 5 mins to start up.
Here are some screen shots of my Graphics card info and then another shot thats drivers installed YES and drivers installed NO. Is that correct?

I just got a replacement Ati radeon 3870 because the first cards fans didn't run at all for a minute or so and would then spin up full for 30 seconds or so and so forth, regardless of what i was doing.
My replacement card came today but this cards fan runs full all of the time?
Surely this is a driver or fan control issue or something, my previous nvidia 8800GT was silent all of the time, but alas I could not play Call of Duty 2 with that card hence the switch.
Is there anything i can do to help cool the card besides fitting aftermarket fans which i don't feel confident doing and they don't seem to support the 3870 100%.
Maybe open up the PCI slots or upping the Mac Pros fans via SMC Fan Control?
Or do i return it and switch back to a 8800gt and forfit Call Of Duty 2 or wait and switch it for a 4870?
I'm going to try and live with the fan noise tonight but does anyone own a quiet 3870?
For the record I'm running a 2008 2.8GHZ 4-Core Mac Pro with 8Gb of Ram and 10.5.6. I tried a clean install on a new hard drive and the card behaved the same.

I have an early 2008 2.8x8, want something that will work in OSX (both DVI dual-link possibly) and also be much better in Boot Camp than my 2600HD.
So, which is better . . . 3870 vs 8800gt? Or another?

Ever since the 3870 came out last year, I've been waiting to see if anyone was able to dump the ROM from the Mac version and flash a PC version with it. But it seems no one was able to do it.
How come suddenly everyone and their brother is now able to flash the PC 4870? Anyone know what the differences between the two are, that would prevent the 3870 from being flashed successfully?

I've seen a few posts with information about 10.5.7 creating fan problems with the ATI 3870 in 2006 first gen mac pro. There didn't seem to be enough complaints to be a definite problem. I would like to hear from anyone experiencing this problem and from those that upgraded and had no problems. I hope that I can upgrade my OS because 10.6 looks like it will be really great, and I assume any problem with the 3870 would persist through the next OS.

Could someone please post the BIOS/ROM from the new Mac/PC ATI 3870 card?
You can write the BIOS file from within Windows/Bootcamp by using GPU-Z. If you do not want to post it here, please consider adding it to the VGA Bios Database at techPowerUp.

I want to use dual 3870 Crossfire in Boot Camp Windows and not have OS X choke.Note I am NOT asking to have Crossfire work in OS X, I just want OS X to use one of the cards while both work when booted into Windows.
Does anybody know, on a Jan08 Mac Pro Xeon, if I install dual 3870 cards with the Crossfire jumper connected, will OS X ignore the jumper and work properly on a single card?
I already have workarounds for power connections.

I'm a brand new member, having acquired a 1st Gen Mac Pro 4x2.66/4GB/4x750GB-HD system at a corporate fire sale and just upgraded it with an ATI 3870 / Accelero cooler. The nVidia 7300 P.O.S. card that came stock in this system was noticeably choppy in Google Earth. I was hoping the ATI 3870 upgrade would put that issue to bed. It didn't. When viewing Manhattan Island with 3d buildings on, it is as choppy as the Gulf of Mexico during an ill-fated fishing trip. But the 4 cores aren't really that stressed - I have iStats Menu installed and they are not maxed. I'm trying to look to the future with this video card purchase (Snow Leopard will support the 3870 for OpenCL operations). Other things seem to be smoother, but I was really looking for better performance with Google Earth and other graphic apps (iTunes visualizer, Core Image demos, etc.) What happened? I'd like this Mac to be somehow faster than my Windows XP box with a Core 2 Quad and a 9600GT card, but it is not so.

Toms Hardware apparently ran a benchmark comparing two 3870s on x16 vs two 3870s on x8 (hence a Mac Pro 2006).

Installed a new 750GB drive into my MacBookPro 5.1 Couldn't get Winclone to make image so I was forced to start from scratch with a new XP installation.
My MBP is partitioned 25%Mac & 75%XP with bootcamp and I have the old drive in a enclosure connected with a firewire. So all of old files are on the external drive now.
After installing XP I have no internet connection, drivers etc... However if I boot up on the mac side everything works fine. (I cloned the mac os already with Carbon copy).
So can I just copy all my old drivers over to the new drive? If yes how and if no how do I get them installed on the new harddrive. The MBP came with everything preinstalled.

I got an ATI Radeon 9600 Pro All-in-wonder in a box of computer junk. Actually, besides a stick of PC3-6400 memory, it was the only thing that wasn't just an empty box or instruction manual

I've seen a lot of HD 6970 reviews hit the streets today. Can we hope to see some "investigation" from Cindori & company in the near future???
I would love to stick a modded version in my 2008 Mac Pro.
Retail on these cards is looking at about $370.00 (Yeah... 80 bucks cheaper than Apple wants for their single-DVI 5870 )
Requires 1 8-pin and 1 6-pin power connector.2 GB of memory on-board.

I have a few question for people who have upgraded to the ATI 5770 form the 8800GT.
It looks looks the install is pretty straight forward. But what type of performance upgrade can I expect? I use manly Photoshop, Lightroom and X-plane. Are there any hidden got-you's?
