6870 over 4870, about 40% more performance (surely some less in OSX), lower temps, lower power consumption, lower noise and DX11 for windows. and double the VRAM.

you say €150 is too much for 6870 but you are bidding €153 for an 5770? not seeing the logic
 
Oops !
Sorry Cindori,
As you notice my knowledge in this area is severely handicapped. I scour online for weeks and can almost always guarantee I'll find a ton of contradictions. That why I keep posting here. You know what your talking about. I keep reading that most of these cards will bottleneck in a mac pro 1.1. As well, on a thread here that recently opened, someone asked what the best card for a Mac Pro 1.1 is and the 5770 was mentioned.
https://forums.macrumors.com/threads/1253747/

I'm at a point where its getting hard to see whats what. Thanks for all the input. I think I got it now.
 
I am a big fan of what you have done to improve the Mac GFX card situation but I have one more favor to ask:
You have managed to make fully PCI-E 2.0 compatible cards with 5.0 GT/s link speed while the rest of us have ROMs that only give 2.5 GT/s. Please explain to us how this is possible so we can all benefit from your wisdom. I don't want to sell cards just use them to their full potential. :)

If you are unwilling to share this secret then can I send you a 5870 so you can make the changes yourself?


Yes, I figured this out. The drag is when I spend weeks or months to figure something out, decide to make that my exclusive thing or card and then the bozos at CrappleMePantix (or others) just take the result and sell it for a lower price. They spend $0 on R&D and then drive up prices on the cards needed to make, and undercut me on the other end. I get squeezed on both ends by clueless hacks who have done NOTHING for the community but help themselves to other's work.

I have worked with Netkas to help provide many new flashing options to the mac community. The bulk of it is handed out for free, no strings attached. If people want to do it at home and save money..GREAT...I even answer questions to help them. (You don't see Crapple doing that)

If people want to take the ATI rome and sell them on Ebay or Amazon GREAT, I think it would be more ethical if they occasionally mentioned who did the work behind their cards, but they never do. But the ROMs are handed out for whoever to do whatever they want. In return, I ask that my pioneering work with Nvidia cards be left alone. My friends (if I had any) could tell you about the weeks spent deciphering WHY a GTX285 2 Gig would not run right with original ROM and then the weeks spent making it work.

When some bozo in Ohio decides he has some right to this work and starts undercutting me by $10 to steal sales that I earned, I wonder why I spent so much time helping people.

In short, the 5.0 "secret" for 4870,5770,5870 and 6870 will remain precisely that. I took one 4 week class on computers when I was 14. If I can figure this stuff out on my own, anybody can. Netkas can confirm that I figured this out, he did nothing to even point me in right direction. I am able to do this with both Nvidia and ATI cards, and I put the hours in to figure it out. Someday I will post a How-To. Not today.

Enjoy the free info.

I will even add a useful bit of info for 8800GT fans. Buy EVGA 8800GTs. They ALWAYS have 128K chips. Another freebie from MacVidCards.

I just ask that the various sellers of flashed cards respect my work and stick to things they have figured out on their own.

If you read the posts by "Beige" on his 4870 1 Gig, you will see that the 2.5 vs 5.0 thing only matters in very specific circumstances. And Starcraft II isn't likely to be one of them.

My "behind the scenes" part of getting these cards available to you all is known by a few. I can honestly say that without me, your options would be much narrower.

And if an Nvidia card is what you need, get it from MacVidCards. We put the time and $$$ into figuring out cards to enable Mercury in 1st Gen and Fermi in 2008 & later. We alone bring new cards out that expand options. The day Steve Jobs passed I decided to release the Quadro 5000 for Mac. I expect to announce the Quadro 6000 for Mac this coming week. Please support our efforts to kep new cards coming. We helped create 5770 and 5870 market and have stayed out of it in hopes that others will avoid stealing our Nvidia work. Time will tell.


Enjoy the free stuff. Unless you need CUDA, a 6870 is a no-brainer right now. Just beware that many manufacturers are switching to a cheaper design that only has 1 @ DP instead of 2 @ MDP. Those cards can only run 1 Apple Display instead of 2 and only 3 displays instead of 4. If you don't care, great, get the cheaper ones. But if you have dreams of Dual 27" Apple LEDs, go for the Dual MDP ones.

The XFX cards use a cheaper 2 wire fan that is noticeably noisier and will certainly die sooner. Sadly, they are also the only ones with a reasonable priced 2 Gig card.

It is quite likely that an EFI32 flash will be available for 6870 eventually. Netkas will most likely be the one to write it. Be nice to him.
 
Help - Cannot Flash Modified 6970 r

With my MacPro 5,1, cannot find way to flash hybrid rom created by following Netkas instructions (http://netkas.org/?p=973). ATI Winflash does not see 6970 (suggests using ATIFLASH - note that Bootcamp does not allow USB drive boot), and I cannot find workable core CD boot image for ATIFLASH. For example, http://www.techpowerup.com/forums/showthread.php?t=57750, Nero example creates boot CD that does not respond to MacPro wired USB keyboard, http://www.ubcd4win.com/ generates an error during build and does not complete (file too large anyway), and apple iBoy's copy of Ultimate Boot CD 4.1.1 (message 226 in this message thread) did not work (no DOS startup). Very frustrating. Until I accidently erased my BIOS in this failed update process, I have been doing extensive 3D gaming with my 6970 (works great with DDD Ignition). Any suggestions for a way to flash the output of RomCreator? I successfully flashed a 4890 using Cindori's clear descriptions some time ago, so I am familiar with the overall process. Running Windows 7 Pro, 64-bit with Apple GT120 for Mac OS (and Windows non 3D display).

Sadly, whenever you erased the 6970 is when you needed to flash the image.

But doesn't your 6970 have a backup BIOS. (switch near Crossfire connector)

Have a look.

Typically, you flip the switch, boot into Windows, and flip switch, flash the card.

DOS boot CDs work easily...problem is you need to have the flash files handy...not so easy.

Look for backup BIOS first.

Once again thanks for all your efforts and the freedom of information you have allowed to make our Macs better supplied with choices.

I genuinely hope your lazy competitors don't make you more embittered as you continue to develop card conversion for the Mac community.

I direct all enquirers to your eBay shop for flashed cards and only pass on my own flashed ones when I upgrade.
I sell for the same price I bought the card unflashed. It owes me nothing so I don't profiteer. Conscience over cash every time.

Let me wish you luck with your Nvidia developments, even though I will be using an ATI card for the foreseeable.

Thanks for great information - I did not know about the switch (great backup, if I cannot resolve installation issue). I created the hybrid rom data file (Netkas EFI + factory BIOS, from RomCreator) before the factory BIOS was accidently erased, so I really would like to test it. Does anyone have a suggestion for suitable ISO boot image (and installation tool) capable of using a USB keyboard? Another suggestion I saw in this thread is to create a special DOS boot partition, but this would also need the appropriate boot image (and seems like a lot of extra work).
 
Hi!

I'm reading the forum since last week because I have a 06 Mac Pro and I want to "re-live" the graphics part. I bought a XFX HD 4890, and I have one doubt (this doubt arrives after reading all the information)

The last OSX that work with this card is the 10.6.5? I have 10.6.8 installed, I'll need to reinstall everything?

Can be a stupid question... but I prefer to ask to be sure to follow the correct procedure.

Thank you very much.
 
Finally resolved CD boot image issue - apple iBoy's copy of Ultimate Boot CD 4.1.1 DID work. I (incorrectly) followed MagicISO web site example for creating boot CD, versus the correct sequence provided in his detailed screen shots (see https://forums.macrumors.com/posts/11167344/).

Unfortunately, the hybrid EFI ROM does not yet work with Lion (10.7.2) and my Mac Pro 5,1 - I just get dark display, even when reseting to Mac OS. Bootcamp (Windows) graphics work normally with hybrid ROM, though.
 
OK the BIG question is...Did you get a boot screen?

(Lower DVI port IIRC)

My 6950 gives a boot screen.

So, no boot screen would be a dead giveaway that ROM is flawed.

Also, keep in mind that 6950/70 don't work in normal 10.7.2 unless you do some hand editing in of the special components Netkas made. Even then, they only work after coming out of a Windows boot.

(ie, you need to have Windows running nicely, then select OSX in Boot Camp, then restart into the Netkas modded 10.7.2. (can't be a cold boot, must be a restart from Windows)

They are definitely not ready for Prime Time. More of a "work in progress" and the issues might very well be Apple not wanting anyone to spoil their "surprise"

The good news is (as Netkas and I discovered the hard way) come hell or high water, you can't bugger up the 2nd Bios. It is locked so even if you accidentally flash BIOS chip #1 with a copy of the Declaration of Independence (or The Gettysburg Address for you Lincoln fans), you can ALWAYS recover the card with a simple flip of the switch. If only all cards had this handy parachute for those of us fiddling with Mac EFI roms.
 
I haven't been following this thread for a while now, has there been any updates to the roms to be able to see the grey apple screen during booting?
 
ROM that see Bootscreen in OS X

So far the only ROMs I have encountered that see the Bootscreen in OS X are 4870 ones. I use my old Apple 8800GT in place of my flashed 5870 when I need to boot into an older version of OS X (i.e. pre 10.6.4) so I can see what is going on. I could be wrong though MacVidCards says he has a bootscreen on his 6950. Others mention 6870s working straight out of the box.
Why not run over to Netkas.org and check out the work they are doing?
Hopefully when Apple finally release new GFX cards either 6xxx or 7xxx based AMD ones along with a refreshed Mac Pro range then folks can make a better ROM based on them.

Thats cool, I still have my stock GT120 in. But I thought I would check if there were any developments since I flashed my 5870.
 
Flashed 5870 has a boot screen on VGA as I recall.

There is a way to get it on DVI but it requires a Dell display or one that has multiple outputs (2 DVIs specifically).

I would go into detail but that rarely helps as people seem to get about 3 words in and then lose focus.

Flashed 6870 in a 3,1 or later Mac Pro has a DVI bootscreen. As do the "problem child" 6950/70 cards. 6870 is the way to go right now.

The fact is, info to create better 5870 roms is all out there to be read. Netkas can't do everything, someone else could step up and do some work on it. But nobody has.

Speaking of which, Netkas finally has a working Donations button. We can at last thank the guy for his tireless efforts to enable "non supported" hardware. If you have a flashed 4870,5770,5870 or 6870 it is Netkas that you can thank. And now there is a way to do that.
 
Hi everybody

I'm new to the forum, I'm a happy owner of a 2008, 3,1 MP but I can't use anymore my old HD2600. I would like to replace it as soon as possible.
I checked all around the web and 5770 to flash seems to be a good option but
6770 seems to work with the same driver.
My budget is 100-120€ and I was thinking about a 6670 vapor-x.
What do you think? Is it difficult to flash it?
I'll use it with 2 DVI, monitors, with FCP and Motion.
The GPU will help me with renderings?

What about if i am running a flashed GTX285.. ? have you got your donation button set up?

cheers

What about audio out through the HDMI port? Any developments with that?
 
A1186 2008 unit

Hi, I found a A1186 at my Girlfriends Apt complex near the dumpster. Missing ram and and video card, and hdd. I would like to test it and use it. I don't really want to invest alot of money in this if it doesn't work. If it works I would like to use it..

I have done hackintoshing a little with some Dells, I have reflashed routers, and cellphones.

So far I found 1gb of memory for $20 bux.
Hdd don't need it for posting.
Video card.. I cant seem to figure out what video cards will work that i can buy currently.


Can anyone let me know of a video card i can get currently that I can flash easily. boot this mac? 256mb/512mb is fine. I live in Portland Oregon USA.

I Forgot it does flash Power LED a few times when power on.

Thanks,
-Gordo

Alright guys .... My XFX 6870 dual fan card should be coming in today. What a long wait this has been. Anyhow I just want to make sure I got everything right. It should be as simple as installing the card + power cables.
- Mac Pro 1.1 - works out of the box with SL 10.6.8
- No Firmware update since my Mac can not benefit due to 64bit efi
- DVD player & Steam will not work.

Pretty much plug n' play. ... Am I right?

I would also like to test out the card to make sure that things are running properly. I know that benchmarking software isn't too reliable, but is there one ( or something) that will at least let me know its running properly?

Thanks for all of your help

I have the same rig and card, and all was swimmingly plug-n-play.

The only oddity is that my DVD player app works fine, but I definitely didn't do any flashing or anything. I don't have any Steam games to try.
 
Probably a dumb question (nobody knows the future of course!) but since I'm pretty sure this thread is read by users "who knows" these kinds of things I'll try anyway: do you think that the ATI 6xxx cards that Apple should introduce with the future MacPro release will have some kind of incompatibility with MacPro 1,1 (2006)?

I've read about 64bit EFI that makes latest card unavailable for 1,1 MacPros... is just a case or all new cards will be incompatible? Or maybe we just need to wait for Apple to release the updated drivers to get 64bit EFI cards variable on 1,1 MacPro too?

Of course I'm wondering about a new card for my 1,1 MacPro... I would get a 6xxx card not just for the potential better performances (even on a 1,1 MacPRo) but for the lower power consumption compared to 5770/5870.


TIA
