I have done the same. It is, basically, one-to-one connection. In fact all pins near the tab side (4,5,6) are connected to GND and all pins on the other side (1,2,3) are +12V so if you swapped two yellow wires - don't panic. I have left one +12V pin unconnected on logic board side because the wires are quite thick and difficult to make a jump wire on the micro side.

thanks mate that was exactly what i was after :) When i first got the card i plugged it in without the power cables and just wanted to make sure that i havent done any damage in doing that?
 
powercolor rom

Hello everybody !
I try to follow all the tread but it is very long and my english is very bad ...
I bought a saphire 4870 512 mb to be sure to don't have trouble but i recieved a powercolor like this one http://omarberrio.com/images/powercolor 4870 512 stalker.jpg (whithout the drawing)
Did someone try the manip with this model ?
It works with the natit of the saphire 512 mb but i can't go on windows bootcamp.

Where can I find the good modified rom ?

Thx to all and one more time sorry to take your time and sorry for my english
 
Sure ?
I tried but it doesn't boot (with ati flashing tool). So I reput the natit and it works again. Maybe I have done it wrong ?

Thx for the quick answer.
 
I hope you guys know what you are doing is illegal. You're only allowed to run OS X on Apple hardware. There is a reason Mac capable graphics cards are more expensive. It's because they're better made and are more reliable. If you are so concerned about price then you wouldn't have bought a mac in the first place. If you want cheap, then stick to hackintoshing, because that's basically what you're doing.

You are so correct, thanks for giving Apple your money.

The moment you bring in third party hardware into Macs, the more chance of them breaking down.

Apple are the most reliable hardware makers exactly because they control everything that goes into their machines.

Could you please elaborate? :eek:
I hope you realise that video card is a peripheral device - this is what P in PCI stands for. It does not "run" OS X. I also have non-Apple made mouse, display and a power cable attached to my MacPro. Should I be worried?
 
Ha Ha hA....

wait, what's that knocking at my door?

EEEEK !!! Its Steve Jobs and the police !!!!

They've come to get me for using a PC 4870.

Someone help me please..........I'm SSSSSSSSSOOOOOOOOO sorry !!!

Help !!! No !!!!!!!!!!!!!!!!!!

LOL. Please reveal your true identity! Your experience with Apple must be a month or two, right? Some people here used Apple stuff before :apple: made a giant leap and migrated to PowerPC.

I would call Apple most beautiful hardware makers (both engineering and aesthetic) but hardly most reliable. Compared to IBM mainframes anyway.

Yep, I'll buy some Apple HDD's and RAM as well next time.

They all come from the same place. Pay 300% more for a little :apple: logo on the goods. No thanks

Dont feed the troll....

Good morning and sorry for being another oblivious newbie asking for buying advice in this thread.
Last night my 8800GT finally died (this is the 3rd card after a dead x1900xt and another 8800GT), and this time I'm unfortunately out of warranty and out of cash too. Since I'm doing a lot of game design lately though, I can't live with the old 7300GT I have lying around. I wouldn't have considered a 4870 normally, but I just stumbled over a dirt cheap demoware card from Asus for under 100 Euros (a Sapphire would be 140).
Sadly, after a few hours of reading I haven't seen any confirmation on Asus cards, neither confirmed working nor confirmed failures.. the closest I got was this post that remained unanswered:


Hi,
i've a ASUS 4870 1Gb and a MP 1,1. I've tryed to flash the vga 2 times.
1st) i 've used 4870.rom but then it dosn't work (the mac dosn't start) so i've re-flashed with original ROM.
2nd) i've followed the istructions of The Rominator to make a personal ROM.
now the MP start but the video is black, but if i plug the monitor on 7300 (in the 2nd slot) i see the desk and icons.
Any idea?

Thanks

I'm almost exactly in the same boat, also using a Mac Pro 1.1, just that the card I'm looking at is a 512MB version - here's the description (sorry, german site):

http://www.schiwi.de/shop4/product_...MB-DDR5-PCIE--HDTV-2xDVI--ex-Demorechner.html

If this card's confirmed not working, I'd rather get an even cheaper card just for Bootcamp and keep the old 7300GT in the 2nd slot for OS X. If there's a fair chance to get it to work in OS X though, I might be willing to bite the bullet and starve for the rest of the month.
Any experience, anyone?

Alternatively, they sell a GF 9800GT for 79,90 - any chance to get that working instead (I'd prefer Ati though)?


Edit: Forgot to say I still have the two power cables from the dead GeForces. Those would work with the new ATI I hope?
 
Oh well, looks like that Asus card is not exactly a standard for flashing experiments. Pity, because paying €40 more doesn't make it easier. :(

I need a new card fast, so I looked around what 4870 brands are still in stock at my local dealers. It seems that XFX cards are the best working ones, followed by Sapphire. Sadly, XFX is not available anywhere nearby, the only card I can find for a reasonable price is the Sapphire 4870 1GB.

After re-reading this thread though I'm all but sure about the flashing results, it seems only the older cards starting with a 1xxxxxxx number are safe. The card I found is a newer 21133-04-20R model, did anyone have positive results with this one?

I must say I'm quite confused about the various Sapphire results and also Cindori's Ati flashing tool that simply mentions "Sapphire new edition". So what exactly is a Sapphire new edition, maybe the card I'm looking at (a question I couldn't answer myself after re-reading all hese 90 pages)?

Another question, before I shed out that money in vain, do the Sapphire cards fit into Slot#1 of a Mac Pro 1.1 without problems? At this moment I have an old GF 7600GS (Windows only) which really hasn't a thick cooler, neverthesless I couldn't get it into Slot 1 and have to use it in a slower slot, something I'd rather avoid with the 4870. Besides only one DVI port working (no problem, single 20" display), do I have to expect any other issues?
 
The Asus card actually looks promising...IF IT HAS THAT FAN ON IT.

Many Asus cards had much simpler, 2 wire fans.

The early cards with that fan were closest to the reference design, closest to Apple's design.

9800GTs are usually flashable but sometimes have 64K/128K EEPROM issue and sometimes have fans at 100% toujour.
 
Thank you for the reply, rominator. However, I'm even less sure what to do now. The Asus card is damn cheap, but I've not seen a single success report on Asus cards (however, nobody tried the 512MB version it seems).
As for the Sapphire, I saw that BEIGE actually had success with that very same card.
I plan to look at the cooler anyway (one reason I want to buy at a local store) to make sure it fits into the Mac Pro's 1st slot, so maybe I could let the heatsink of the Asus card decide for me.

If I tried the Asus card, I guess I'd have to make my own ROM, right? Which is rather intimidating, I must admit. My head's already smoking from all these reports. At this moment I'm leaning towards Sapphire.

Edit: Ack dammit, he also mentions the screws on the Sapphire being too large for slot 1. Now I'm completely lost. :)

And then there's of course the 9800GT question. I couldn't find any thread like this anywhere for nVidia cards, are there some brands that work for sure? Being low on cash, the difference between 80 Euros for a 9800GT vs. 140 for the "almost safe" Sapphire means a lot.
 
*the hunter returns with an arrow-pierced 4870 on his shoulder*

In the end it turned out to be a MSI R4870-MD1G card, once again a card without a ROM in the Atiflasher app, sadly.
However, I found this thread here and it looks like I can indeed get this card to work. There's just one thing, and that is I can't get the ROM he posted without a Rapidshare premium account. :((
Can anyone do me the favor and repost it, or point me at the best way to make my own? Is the original Mac ROM used as a base in this thread still the most recent one, or have there been updates? For the record, I already dumped the original MSI ROM using GPU-Z.
It looks like a lot of the flashing procedures from the beginning of his thread are obsolete now, or there are better "recommended" methods.
Heh, sorry for being a pain, I'm extremely nervous now, especially because the card seems to work flawlessly in Bootcamp already and I'd like to keep it that way. :p

Edit: Just figured I can't even get the original Mac ROM from this thread without a Rapidshare premium account, so I'm kinda stuck at this point.
Edit: The original ROM as attachment

the method for making a 4870 ROM hasn't changed a lick...the great & mysterious genius Pipomolo42 posted method and I think it is linked from begining.

all that is changed is that Cindori has made it easier to flash in OSX using a trick that was again discovered by pipomolo42.

As you already have Windows loaded, you should probably flash in DOS

If you have done all right, when fixrom.py runs it will show 2 @ "oproms", one of which will have a different checksum in "after" section.

Also, the first "oprom" will have the 80 "last rom" flag changed to 00 as I recall.
