yes... and you need 4870 drivers you can find on netkas.org (but remove natit.kext, it's only needed for hackint0shes).
Waiting for results. If PC cards are running without any issues, I'll cancel my order from Apple.
Yes, I'm keeping a close eye on this too. I have a PC version 4870 that I'd like to see in my 2.8 octo. Not doen anything like this with ROMs before though. Hopefully some kind-hearted soul will post a step-by-step-for-newbies guide for us, once they've confirmed it all works?
Also, does the 2.8 octo have appropriate power connectors for the 4870?
I just tried it on my Sapphire HD4870 (the 1st gen one, based on ATI's ref design).
I flashed using freedos and the following command line :
note : -fs and -fp are used to ignore SSID and P/N mismatches
And it works!
EFI driver is initialized correctly, (I don't have the leaked MacOSX drivers for this card, so I can't tell if this one works too), and bootcamp stil works (currently writing from GNU/Linux on my 2006 Mac Pro).
Only problem is : only one output is active, no dual-head, it seems (at least using ATI's linux driver)
Just to clarify, you only get single head mode in OS X as well?
Can you test after you get the drivers if quartz/opengl accelerations work correctly?
pipomolo42, I pmed u a link to osx 4870 drivers.
netkas, are they the same ones from netkas.org?
what is the link for the osx 4780 drivers please?
yes, just remove natit kext after installing
Ok, I tested your driver, and it works fine.
So, it seems my first assumption was wrong : dual head DOES work in MacOS X, but analog output does not.
Here is a screenshot of system profiler with both a LCD display, plugged in as DVI, and a TV, plugged in as DVI using the HDMI to DVI adapter that was included in my ATI 4870 box, and both work.
Whoa whoa whoa. Are you confirming that a 2006/2007 Mac Pro can in fact run the 4870 with the reflash?
Fantastic, means i can scrap my order for Apple's 4870 and use a far cheaper PC version.
Of equal (if not more?) importance, it means those of us with 2006 and 2007 Mac Pros aren't getting totally hosed.
What I'm realllllllly curious about now is if the 1GB card will work or not.
Well, I didn't run any benchmark yet. And a VGA output won't work. But otherwise, it looks OK.
Great new, Tommorrow i will go to my local pc store and bought 4870.
ps. anybody with 4850, 4830 flash this rom please.
VGA's dead to me, so that's no big deal. Looks like I'll order one on Monday
hopefully by then someone will have tried with a 1GB card so we know if those work, too!
u can also try this -
open this rom in RBE and on clocks tab change all ram clocks to 900 (from 850), so your card will run at stock ram speed, not undeclocked
There's tons of manufacturers of 4870 cards out there. What's the best 3rd party PC card to buy for use in a 2008 mac pro?
I'm looking at http://www.overclockers.co.uk/productlist.php?groupid=701&catid=56&subid=939
Forgive me for asking but how come we still need to dl the drivers? Does OS X not yet have stable 4870 drivers built in?
Looks like Newegg has a "Weekend Special" on the Sapphire 1GB 4870, only $189 compared to the Sapphire 512MB 4870 which is $179. I'm really tempted to pull the trigger on this one! LOL.
That's what i'm going with Figure i'll get the special now, and if it doesn't work i'll put it in a PC needing an upgrade.
