Mac Pro :: Having Trouble Installing Flashed Sapphire 4870?
Nov 6, 2009
i recently bought a Sapphire Radeon HD 4870 512M GDDR5 PCI-E DUAL DVI-I/TVO SKU# 21133-00 S/N 180825044742 flashed with mac firmware.
The instructions said to take out my existing card put the sapphire in slot 1, then boot up and install drivers.
So i took my Nvidia 7300 GT card out of slot 1 and put in the 4870, then started up. I get the grey start up screen with the apple in low resolution for about 8 sec, then the screen just goes blank.
What am i doing wrong?... do i need to keep the Nvidia 7300 GT in slot 2, then boot up connected to that first?

I went for flashed Sapphire 4870 512 off eBay for my Mac Pro 1,1 running SL 10.6.2, with two Viewsonic VP2030b. The guy selling the card had sold flashed cards before and had 100% feedback, said the card worked with dual monitors and supported SL. Got the card, installed it without a problem, but could not get it to work with both monitors. Second monitor said no signal on both DVI channels. Checked all the wires, reinstalled, rebooted, no luck. Plugged both into my 7300GT, no issues at all. At one point, I got the left monitor to boot as the extended desktop, showing the dock but not showing the HDD or icons (which should be on the right screen), but the right screen still showed no signal and was black. Used the gather windows botton in the display preferences to see if adjusting settings helped, still nothing. Detect displays button was no help either. Is this a compatibility problem on my end or a flashing problem on his? Contacted him and he said he had no issues with his MP 1,1 and two 20" Apple displays.

I have a MacPro3,1. It currently runs 10.5.7, and I use it for development. I bought Snow Leopard on Friday, and I'm worried about installing it. I have a flashed Sapphire 4870 card running in addition to my 2600 XT (stock.) I made the BIOS with which I flashed the card using a python script I found on MacRumors.
I know the card works pretty well in 10.5.7. I have Dual-DVI, rotation support, and Quartz Extreme working. Sleep does not work (crashes the machine) but I'm pretty okay with that; I seldom sleep the Mac anyways.
I understand that to get everything working in Snow Leopard, I have to add the device ID to a .kext file that is installed with Snow Leopard.
I've found the device ID in System Profiler on this line:
Device ID:0x9440
Is this the right line to look for a device ID? Should I be looking somewhere else?
Also, on [URL], netkas says "just need to add dev-id into ATI4800Controller.kext." for my kind of card. How do I add the device ID to the kext? I think it goes somewhere in info.plist, but I'm not sure...
Will I still have Dual-DVI? It's very critical that I have it working, so I'd like to make sure before installing the new OS.

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 have a Mac Pro 1.1 and I've been successfully running a flashed XFX ATi 4870 card for a month or so.
Yesterday evening I left my computer in sleep mode, when I came back it appeared to be awake with only one of the two screens working and everything frozen. Both screens were connected to an Apple ATi 2600 XT and nothing was connected to the 4870.
I held down the power button and restarted, the fans on the graphics cards ramp up and then down as usual and the computer makes the startup dong noise. I can hear the hard drives and optical drives working as usual then the drives appear to shutdown and I'm left with the computer apparently doing nothing.
- Fans are running
- Screens are in standby (LED's on)
- Both screens are connected to the ATi 2600
- 2 x 20in Apple Cinema Displays
- Nothing is connected to the ATi 4870
- No LEDs are lit up inside the case
Once I remove the ATi 4870 the computer starts up normally, putting the 4870 back in give the same startup problem.
Is there anything I can do to get the 4870 working again?

I am looking at putting one of these cards in my first gen Mac Pro and was wondering if anyone has had any problems with compatibility issues etc.
I am looking at getting one from bruinmacs and was looking for feedback from others that may have bought one and whether there have been any problems.

I have just ordered a xfx 4870 that will be placed into my mac pro 2006 (1.1). I dont have the infamous power cables from ati so i was wondering if it would be possible to use the power from the optical drive. i have two 6-pin pcie power cables that each connects to a 4-pin molex. i addition to these i have a 4-pin molex Y splitter.
With this setup i should be able to feed the card with power but is this dangerous or will the system be unstable? what will happen

I recently flashed my Sapphire 4870 1gb card and haven't been able to get dual monitor support working in Mac OS. Has anyone been able to get this working on a Sapphire 4870?
It works fine in Windows, not sure why it wont work in MacOS as I imagine the 10.5.7 drivers should be doing all the work.

09 Quad Mac Pro, with flashed 1g XFX 4870 ...
all the OpenCL sample apps from Apple, except for the "hello world" example, are failing.
Can anyone else confirm the same errors on their setup? Just so that I know for sure it is due to the 4870.
I will try putting in my GT120 and see what happens.

I've got a 1GB XFX 4870 that I flashed using the info from the exhaustive 4870 flashing thread. It's being used in my Mac Pro with a GT120 and I use 3 monitors.
When using Aperture 3 the 2 displays that are attached to the 4870 exhibit graphical glitches when performing adjustments...
The glitches range from a garbled mess of of the original image, to being able to see the previously viewed image very briefly. After I've performed one adjustment on the image the adjustments work as they should. The display with the GT120 performs fine with fairly smooth performance.
This was not an issue with Aperture 2.
Are there any other users of flashed 4870's and Aperture 3 seeing this issue?
I thought that the card could the card be failing but it still gives stellar performance everywhere else including gaming in Windows 7.

by following the very active community you have set up for the scene of flashing PC cards to work under OS X I myself bought a 4870 XFX ZWFL & ZWFC 1GB and flashed it.This occurred about one month ago, and since then the card has been working flawlessly, so a big thanks for that.
A very nasty problem occurred after the 10.6.3 update tho, as since then I started having horrible fps's in any application that required 3d acceleration (say, World of Warcraft); down from a rock steady 50-60fps (that easily topped the 120 mark) i can barely get a 30fps after the update.
I checked the other topics, and all of them pointed me into downloading the last version of Zeus and update the drivers, wich I did for every time an update (or fix for a fix) as been released, and tried every time to install both before and after the reboot from the 10.6.3 combo update.
I'm using only one monitor, so I did not encounter any problem concerning dvi ports not working or anything.

I'm running a Mac Pro 1,1 with a flashed ATI HD4870 - everything has been fine since getting the card back in March - played HL2 and Torchlight with nice framerates and no problems.
I bought Starcraft 2 today, partly to give the new card a proper workout.
Everything looked great to start with ? smooth graphics, nice lighting effects etc. then I started to get flashing lines and angular artifacts appearing all over the screen.
Now, thing is, this is what happened to my old X1900 XT when playing WoW. At first just slight graphic glitches and flashes but, over time, getting worse more quickly until the game became unplayable within minutes of starting it up. Getting the HD4870 fixed this and I was able to play WoW no problems after that.
I'm just wondering if this means my card is (already) on its way out - deteriorating like the X1900 did - or if it's something else in the computer that might be showing signs of stress?
I haven't seen anything here about the HD4870 failing on Starcraft

I guess curiosity got the best of me and I attempted to re-flash my working Sapphire 4870 with a different bios image provided here, and now when I boot I dont get any video. Just a black screen and no chime.
After this I tried putting in my old 7200gt to try and get it to boot so I could reflash back to the old firmware - but as long as the 4870 is installed I get no video at all. As soon as I take it out everything works fine.
Please advise me on what to do next.

I have a new issue with my Mac Pro (3,1 - 2008), it just popped up (and I don't think it was caused by 10.6.3, I remember this working correctly after it was installed I have two monitors connected via DVI to a flashed XFX 4870. The 4870 has never given me any trouble.In the Energy Saver settings, I usually set the machine to never sleep, and the displays to sleep after 5 minutes. This used to work great, never had any trouble with it, ever. Now, the displays don't go to sleep after 5 minutes, they just stay on with a screensaver.

Apparently, Apple is seeding updated Graphics drivers .
Can any of our GPU gurus hazard a guess at whether these will benefit those of us with flashed cards, or will they more likely brick them, or do we just not know until we test them?
I don't want to get my hopes up for improvements that might never happen!

So I have an Early 2009 Octocore 2.93 and I have a flashed ATI Radeo HD 4870 video card that is supposed to work on a PC but its flashed so it works on a mac. I know its not officially supported but the issue im running into is that the operating system cannot recognize the full resolution the HP LP3065 30 inch display is capable of. The display can run up to 2560x1600 on any other system but not with my ten thousand dollar machine. The windows side can display at the full resolution but Snow Leopard can only run 1280x800 and it makes the OS look like a pile of dog **** on sunday.
Anyone else run into this issue?
Heres the link btw to where this guy shows how to flash the card.

Using the ati flashing tool I flashed the XFX 4870 1GB ZFWC. When I start up a dialog shows up saying the cables are not connected, when in fact they are (I have double and triple checked). Also when I put the computer to sleep then wake it up a weird distorted blocky pattern appears and I have to restart the computer to fix the problem.

OK so i currently bought a brand new 24" imac and am trying to print from my MP610.The printer is running off a wireless network and i have no trouble finding or connecting to it.I downloaded the most recent drivers from the canon website,( 6.9.3) and installed them. However the problem is i cant seem to find them anywhere in the computer. The driver does not show up in the selected driver list, and i can't see to find it manually either.

I bought HIS Radeon HD4870 512MB DDR5 for my Mac Pro 2006 1.1. The first problem I've found it that card will not fit to slot 1, because of too long screws. So I installed it in slot 2, leaving 7300GT in slot 1. The next problem was how to get rid of these power cables - I've tried the more elegant way taking that molex adapter under HDD trays, but cables where too short So I installed them on the right of Superdrive's tray. Now on Mac OS X I got kernel panic (probably the injector thing). On Windows Vista card is detected, but automatically disabled (probably not enough power or just PCI-EX 1x slot is not compatible). Here are photos from the operation. I'll try to install Accelero S1 rev. 2 with Noctua 120 mm fan and will see how things go I've also ordered two special Apple PCI-EX power connectors from Austria.

I have a 2.8 eight core Mac Pro. Recently I was copying home video captured by IMovie to a WD external book drive. It froze and I had to force quit the copy process. Now I am unable to use anything by USB except my keyboard and mouse. The computer will only occasionally recognize and record files from a thumb drive or a photo card. I don't know if I have a software or a hardware problem.

I have a an old G4 running Mac 10.3.5 that I need to update to 10.3.9 to run a program. The machine has a long boot time so I'm worried it might die soon.
Anyways I am wondering if I should click "repair permissions" and/or "verify permissions" before I do the 10.3.9 combo update. Will this increase the chances that the 10.3.9 update will not cause problems? Or can repairing permissions itself cause trouble?
I have never repaired or verified permissions on this machine.

when I put my usb stick in my mac under the search for section in the finder my pics and docs come up. As soon as I take my usb out they all disappear. Does this mean that they are on my mac or usb.Im really having trouble understanding the relationship between the OS and USB.

I installed SL the day it was released and am having several issues that I cannot figure out.The installation was over Leopard on a 2.93 GHz 24" iMac with 4GB ram. I'm having the most trouble with Photoshop while trying to "Save As". Photoshop will just crash hard and close without saving any of the changes I made to the file. I've tried saving to alternate locations (i.e. desktop, etc) but still get the same crash.
Another little annoying quirk is when I need to confirm an installation, the text in the window is garbage.

So I just installed an Intel x25-M into the hard drive bay of my MBP 15" i7, and put the stock HDD into the optibay.Installed OSX onto the SSD, wiped the HDD clean, everything seems to be working perfectly.Disabled SMS, disabled hibernation, all fine. I would like to enable noatime, but for the life of me can't figure out what I'm doing wrong.
After I restart, I check the status of naotime in terminal (as directed) but all I see is "hfs, local, journaled" and there is no indication of noatime.
