The limitation for getting a 4870x2 working in OSX seems to be the lack of crossfire support. Crossfire is available in Linux and BSD, though I'm not sure to what extent and how well. So serious question time: What will it take to get crossfire working in OSX with the goal of running a 4870x2??? Seems to me it should be possible, I just don't know how.
View 4 RepliesI have on order a Mac pro 8 core with all the goodies, stock video card is the 8800GTX. I would like to know if any of you have ever ran SLI or Crossfire?
I have heard several opinions on SLI and or Crossfire and know they are not supported in OSX, but has anyone successfully ran either in Bootcamp Windows? I would assume Crossfire is easier than SLI as SLI is chipset based but I heard a hacked driver exists.
I would love to replace the dual 3870s in my early 2008 Mac Pro with this one card.
View 9 Replies View RelatedI have a MacPro here with a 4870x2 connected, (using Apple's mini onboard PCIe 12v rails to supply power) in slot 2. (1x 24" Dell connected via DVI)OEM 2600 is in the 1st/bottom slot. (2 x 24" Dells connected via DVI)
I Decided to upgrade from Leopard to Snow Leopard, but am having a hell of a time getting the 4870x2 up and running. (PC side is obviously fine)
A couple of questions...
First of all... anyone got the 1-core driver active and happening so far? because I just assumed that it would be, considering it worked in Leopard.
Secondly, do I use the same instructions/howto that's for hackintosh's over at this forum?
I have tried the above, (both the "accel" download and the updated instructions/downloads to no avail)
At the moment, a vanilla install knows the card is there, as the "Arrangement" tab in the Displays System Preferences is coming up with 3 displays connected at 1920x1200, but the Dell screen connected to the 4870x2 is black. (orange standby light on)
After applying the updated instructions from the above link, I get a corrupted array of horizontal pixels just after the grey Apple logo on my 2600HD connected Dell screen. Other 2 displays are black during this and the whole machine is locked up... (not KP'd but screen sharing is not available either)
If someone has got this happening, could you please carefully outline your procedure step by step and also include links to files you used to get this card happening in 10.6.
a few weeks ago i asked about installing a HD4870x2 Monster in my new MP4,1 just for using in windows.
I ordered those 2 power cables to connect the gpu to the mainboard but when both cards are in the mac (gt120 and hd4870x2) the system won�t start to any OS either mac nor win7.
This is the first time I've tried OWC memory. So far, so good - the Mac recognizes the RAM and boots okay. Everything I've tried thus far post-upgrade works. I am a happy camper now - my Mac was a bit sluggish due to running out of physical RAM running Parallels.
View 1 Replies View RelatedI have a 2006 Mac Pro and I'm wondering if CrossFireX is possible on this system. Specifically with two 5770s.
My understanding is that CrossFireX requires two PCIe 2.0 16x slots. However, the 2006 Mac Pro only has PCIe 1.x slots, and with two cards, it's only possible to have its slots running at 8x. Does this prevent CrossFireX from working at all, or is it simply a case of it working fine but running at reduced performance?
So because apple has done almost nothing about the 8800 GT being available for 'older' mac pro owners and almost nothing to live up to its claims that mac pros would be easily expandable, ive been thinking about alternatives a graphic card upgrade.
Currently I have 2 Geforce 7300 GTs, bridged with an ASUS Flex bridge, and overclocked. I get about 50-100 fps constantly in Counter Strike Source, and about 120-170 fps in UT 2004, both at resolutions of 1280x1024, 4X FSAA and maximum detail.
I'm becoming very tired of my small 19" LCD as im a graphic designer and am in the process of buying a 24" LCD which woud give me 19200x1200 resolution. This of course, would kill my geforce setup and drop my frame rates significantly.
Now, I've been thinking of upgrading but am not sure which video cards I should get...1900 XT or 2 X 2600 XT and overclocking them. Is the dual 2600 XT even an option? Can they be crossfired? Overclocked?
I've been playing half life 2 and am ready to move to half life 2 episode 2, but im fairly certain my video cards wont handle the game at the same settings i currently have. Of course, there are other games i would want to play but my limitations dont allow it, more importantly, at 1920x1200 resolutions after the monitor upgrade.
Obviously only under windows, i could find on google any macpros with CrossFire. Anyone here managed it.

Also do you have to download a program to start crossfire or does it just work?

This is a cool video check it out and tell us what you think
It's no big secret that today Apple announced that the ATI 4870 will be available sometime in the near future for the new Mac Pros and some of the other recent models.
So the question is for those of us who are running a single 3870, is it worth dropping it for the 4870 or better to go 2x3870 in crossfire. This is more of a question geared towards Windows usage and not OSX since OSX doesn't support crossfire.
Just a couple of weeks ago I purchased the Mac/PC edition of the 3870 from OWC and added the Accelero passive cooler to it and it's working out well.
I was thinking about buying an additional 3870 to crossfire sometime in the relatively near future solely for the purpose of Windows gaming since you can get PC versions of the 3870 for so cheap.
I'm guessing the Mac edition of the 4870 is going to be pricey so would the dual 3870 option make more sense?
It seems that with this technology and with Snow Leopard coming out that this should be a no brainer. However, the recent refresh has shown little signs of picking this up. The Mac Pro has had multi gpu options for a while so nothing new there, but the iMac didn't get anything in the way of multi GPUs. So with the Mac Pro and the MBPro having multi GPUs, it may just be that their saving it for their pro line.
Since Snow Leopard is supposed to bring about OpenCL which will use the GPU, why have we heard nothing about SLI or Crossfire? These would greatly benefit the system. It seems to me that Apple could benefit greatly from using this technology, not just for the OS, but for a better hardware position.
I have two Apple 5870s on hand, a modular power supply on order as well as a crossfire bridge connector. I am taking it upon myself to rearrange the mac pro with two 5870s and test whether or not crossfire will work under Windows 7.

8800gt vs 2 3870 crossfire
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 have a smartdisk (now verbatim) crossfire xf 250 standalone hard disk that i use to back up g3 and a g4 mac ibooks. although the disk reports, when i check via "get info," that it has 98 gbytes of free space, and shows thousands of files that have been copied to it, i cannot copy more files to this disk - i get the message that the disk is full.

Basically, I cleaned up files and 'other' system preferences. Things seemed to be fine and the computer did run much better. However, after running Monolingual and deleting what I understood to be 'unnecessary' PowerPC files the standard USB keyboard is no longer working.I've tried to search for various remedies, but have come to a dead end. So I'm left with reinstalling the Snow Leopard OS (I think it is 10.6.8?) BUT I can't because it is asking to input the account password (which I know) to make the change and I can't figure how to do that when the keyboard not working.

I have a MacBook Pro and sometimes run VMWare Fusion / XP so that I can sync some older Nokia phones I have (that only run on PC Suite).However, my older phones don't utilize cables...you can only sync with Bluetooth or IR.I opened up the Control Panel and looked for a "Bluetooth Devices" icon, but couldn't find one.Then I opened up the Nokia "PC Suite" and Connectivity window and it gave me the option of clicking (ie: selecting to turn ON) Bluetooth and IR, but when I did, it said that this function was not available.What am I missing?My MBP obviously has all the Bluetooth and IR whistles, but when running VMWare Fusion / XP, the computer seems to disavow any knowledge that these options/functionalities are installed and working on the Mac side.

The iTunes application froze. He called me and after seeing it crashed, I right clicked on the iTunes dock icon and force quit the application. I restarted the iMac and after it rebooted I clicked the iTunes icon and iTunes opened without our music libraries, just as it was when I ran iTunes the first time when the iMac was brand new.

I have a mid-2009 Macbook Pro running Lion 10.7.4. Since I upgraded to Lion the external display stopped working altogether. After connecting adapter to laptop the screen on the laptop goes blue for a moment and then returns to normal. However, the external display is never detected.
I searched in forums before sending this message, but most problems I found are related with some glitches of the screen and they seem to be getting some image in the external monitor. In my case... it simply stopped working at all.

My iMac keeps semi freezing. When I click the mouse and the little color wheel begins to rotate it always freezes. It cannot complete an order to open a program or even take any action. Not even the internet works. To quit I have to unplug the computer. Force quit and even the on/off button doesn't work. I'm running 10.6.8.
View 2 Replies View RelatedI bought an iMac on dec, 2010 it came with snow leopard and a wired aluminum keyboard, everything was good until dec, 2011 when my keyboard suddenly stopped working, I took it to an apple store and they replaced it, everything was fine until last month when my new keyboard stopped working again.
I have an old macbook (1st gen of intel-based macbooks) and if I connect the keyboard to that macbook it works just fine, I have checked and all the USB ports on my iMac and they work but when I connect the keyboard it just doesn't recognizes it as a keyboard (or as anything because it doesn't show on system profiler). I have connected another keyboard I own (a logitech wireless one) and the imac recognizes it, I don't know what to do.
Btw, if I disconnect the keyboard for a day or two it works again when I connect it to the iMac, also If I use the USB ports attached to the keyboard I get an error that the USB is taking too much power and it shuts down (and then the keyboard stops working again on the iMac)

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.
