Considering that the Macpros PCI E16 slot is double wide (thank you apple) I was wondering if anyone yet knows if it is possible just to add a double wide PC graphics card?

Also, would any OCZ ECC 667 Ram work?

No word on 3rd party graphics yet.

OCZ ECC would not work unless it is Fully Buffered or an FB-DIMM. On Newegg on Kingston and Crucial have them.

Thanks for the reply on the memory.

Newegg is the best, Newegg+Mac is even better.

Some people that have ordered MacPro's have 6600's and 7800's lying around, and are willing to try 'em out. My guess is that it will work, but I just gotta ask, is the 7950GTX superior to the X1900 or the Quadro FX4500?

The 7950 is like two video cards on 1 card. Im sure Apple has em wide for future stuff like the 7950 and the higher power/heat cards to come.

The Quadro isn't in the same league as the 7950GTX and the X1900XT. So it cannot be compared realistically.

And I think the X1900 is superior to the 7950GTX

Im talking about the 7950 GX2 by the way which is two GPU's on 1 card. The X1900 isnt faster then a 7950 GX2 according to PC gamer but you are comparing two 7900s in sli on 1 card vs 1 Ati. I find a lot of this funny considering monitors are only drawing at 70-80 FPS and anything higher is waste of power.

You're kidding right? NO!
The x1900 is NOWHERE NEAR as good as the 7950GTX

In fact, the 7950GTX is the best consumer card IN THE WORLD.

Hence I said: "I think". So save the drama. Most people favor the X1900XT over the 7950GTX.

kevin.rivers, what do you mean the nVidia Quadro FX4500 512 MB GDDR3 isn't "in the same league" as other high-end nVidia and ATI cards? According to Applr's test, the Quadro is better than the X1900. I wouldn't know about the X1900XT or the 7950 GX2, but please enlighten me.

BTW, michealdmartin, no reason to troll by laughing at other members. he just though ATI's high end card was better than nVidia's hi-end card. I thought that too.

The FX4500 is a card for 3D graphics people. Hence it is a $1300 upgrade over the X1900XT.

That is why it is not in the same league. Would you pay $1300 for 4-10 more FPS? Would a 3D guy running Maya pay $1300 for 60 FPS real time rendering as opposed to the maybe 10 FPS you would get on a X1900XT or 7950GTX? Heck yeah they would.

So no, they are not in the same league. Sure the Quadro has great gaming performance but its uses are very different from comsumer cards.

PC graphics cards are set up to use a standard BIOS.
Mac Pro graphics cards are set up to use EFI.

Unless you can find some EFI firmware for your PC graphics card, it's not going to work.

Wow, I thought most people knew that nVidia made the fastest cards in the industry :)

The 7950 GX2 has everything splattered (http://www.anandtech.com/showdoc.aspx?i=2769&p=9) especially when you pump up the resolution and throw some AA in.

Someone posted earlier (can't remember where now) that most current-generation graphics cards already support EFI. That makes sense, especially since the stock 7300GT in the Mac Pro works with unmodified Windows ForceWare drivers.

Edit: I should note that I'm talking about getting a PC graphics card to work in Boot Camp. Getting Apple drivers for a card such as the 7900, which has never been in a Mac, will be another story. If it's not working now, I wouldn't expect it to take too long for someone to work something out, though.

just a thought....

Being a gamer, and knowing where alot of you are coming from. I know the thought of droping an SLi into my new Mac Pro definetly have crossed my mind many times.

Now, as a disclaimer, Ive never worked with an Intel Mac. But Ive read alot about it, and been following Intel Macs since the MBP was announced. After I saw them announced, I knew I wanted to go ahead and order which ever tower eventualy came out with an Intel chip. That being said, I put my order in this last monday, and have been scouring the forums on more information on the limits of these machines since then.
One of the reasons I desided on this computer, was for games. Thats definetly not the only reason tho, but that being said, I knew I wanted to tune up this computer as much as possible for the games.
Im figuring (as alot of people are) that the use of the 7950 (or other SLi on a single card, boards) is probably dependant on the drives.
We might get drivers, we might not. Who knows.
We know that we DO have a 16x lane to work with, along with other lanes that are decently fast.

And knowing all this, I was kinda suprised that no one bought up the idea of dropping a 7950 into the Mac Pro with the intention of ONLY having it run under windows.
At this point, I see Mac Pro users not having drivers, or any other hacks avaible, a worst case scenario.
But if this did happen, why not just pop that 7950 into the 16x lane slot anyway, and then also have a 7300 in one of your 8x lanes (or even 4x).
While I havent messed around with modern macintosh intel hardware, im sure theres a way (and probably even an easy way) to put in that 7950, and then just disable it in the hardware profiles, so that it doesnt run while the computer is running as a Mac (you would be using the 7300 to display the mac stuff), but then dual boot into Windows in order to use your 7950. While in windows, just install the normal drivers for the 7950
Asuming plugging a "Non-Apple" video card into the Mac Pro, doesnt fry the thing, I dont see how it couldnt hurt it.
Sure, you would have to switch your monitor cable every time you wanted to do your PC Gaming (is there a DVI monitor switcher?)
But having a definet way to run SLi inside your mac, with only a few minor inconvinences beats the hell out of not having it at all.

So yeah? Is this technicaly workable, or??

And knowing all this, I was kinda suprised that no one bought up the idea of dropping a 7950 into the Mac Pro with the intention of ONLY having it run under windows.The PCI Express Lanes require configuration...

Using the Configuration Expansion Slot Utility, the bandwidth of the four PCI Express slots can be reconfigured as shown in Table 1.

The Configuration Expansion Slot Utility is located on your Mac Pro at: /System/Library/CoreServices/.

Table 1 Configurable PCI Express Bandwidth
The Mac Pro has 16 PCI Express lanes from the North Bridge and 12 PCI Express lanes from the South Bridge

PCI Express Slot Default Configuration Alternate Configurations

1 x16, NB x16, NB x8, NB x8, NB
2 x1, SB x1, SB x8, NB x8, NB
3 x4, SB x1, SB x1, SB x4, SB
4 x4, SB x8, SB x8, SB x4, SBBut remember you CANNOT have a bunch of high power cards in the machine ...

Wow, that's a long post, i'm trying to understand most of it. The thing is the Mac Pro chipset is not SLI compatibale (Intel 5000x i believe). So you cannot have an SLI or Crossfire setup in the Mac Pro

thats the thing tho, this isnt a normal SLI setup. Its a 7950, which is basicly 2 GPUs on one 16x PCI-E Card. (the one we've been talking about this whole time)

Thing is tho, we know this chipset doesnt support SLI in the typical sense. It does support this card, since the whole SLI thing is self-contained on the card. So while its not "True" SLI, its still a form of SLI that would work on the mac.

Here, let me explain it this way.

Buy a Mac, keep the 7300 in there, then go out and buy a 7950 and stick that into the 16x lane, and then move the 7300 into either a 4x lane, or an 8x lane (if your not gunna add anything else, you should configure it for the 16x,8x,1x,1x to keep the most bandwith for that card)
Lets say, they dont release the drivers for the 7950 for the Mac, thats okay if all we were really going to do with it is play games as a windows machine.
Because we can (I think) "disable" that 7950 on your Mac, so you will never even bother with it, and then use that 7300 as your primary card while using the computer as the mac.
But then when you dualboot into Windows, You can disable the 7300 (or keep it if you like, doesnt matter) but then have the 7950 active there.
And from there, since its a standard PC card, and the whole computer is basicly acting as a standard PC, you can install the normal 7950 drivers for it, and that way, you could esentialy get a form of SLI running on your Mac Pro (as long as your in XP SP2).

Is there PCI devices that use 4X PCI slots other than graphics cards?
not really sure but ive always thought 1X PCI slots are normal or like soundcards or liek USB2 cards and stuff liek that??

i am planning to get the 7950 GX2 for my Mac Pro and like mentioned above
i am thinking IF OSX doesnt' support the card.. then my last resort is using bootcamp to use the 7950 GX2 in windows and use 7300 for OSX

althought hopefully it will work and Nvidia says 7950 GX2 supports OSX
but not sure until someone tries it out

Oh, just guessing:p , but now I see BlizzrdBomb saying that the 7950 GX2 "gas everything splattered", and I looked at his article. I saw that it's better than the X1900 XT and all the hi-end nVidia cards, but in that comparison were only 7800, 7900 and 7950 cards, no Quadro cards at all, which is why I'm still in doubt. I still believe the Quadro's are way better, but the sentence that it" had everything else splattered", made me think twice...

Quadros are not gaming cards. They are ment for Graphics professionals.
They are made for 3DSM, Maya, and other such things.
The reason you didnt see that in the compairison, is because theres no compairison because its not a gaming card.
Compairing a 7950 to a Quattro is like Apples to Oranges.

I dont know why you guys keep thinking the 7950 or Nvidia in general has the best card. So far many gamers perfer the x1900xtx as it performs the best. True a 7950 GX2 card can definitely beat it, as can the 7900GTX beat it in some applications (it is pretty much even), but it doesnt lead by much, and you pay a very hefty price for the performance you want. 450 for x1900xtx, 500 for 7900gtx, and a whopping 600 for the 7950GX2. Id rather save the money and still get about the same performance.

Remind you, these cards are built with gamers in mind almost entirely. If you want a professional card, Nvidia provides them in their Quadro line so it is no use in comparing it.

And finally the 7950GX2 WILL NOT work on the Mac Pro more than likely. Why you might ask? Well Ill let the Nvidia webpage answer this one...

Excuse me, no compairisons?
Check out Apples compairsons of the offered cards. The 7300 is an embarrassment. Period. Gaming aside, those that choose this card may well find that Apple doesn't offer upgrade graphics cards. I learned the hard way, choosing the low end card for my G5 dual 2ghz. When Apple finally offered better cards they were available ONLY on NEW built to order machines. No faster Photoshop for you! There is a very small upgrade path to be had, better make the right choice the first time or be stuck.

http://www.ipspty.com.au/computers/xeon/x-3.htm

This company sells Xeon Workstations, with the 5000x chipset (The same as the Mac Pro) and they sell the 7950GX2 as an option.

The only problem will be getting drivers. But I dont see any problem with putting the card in there, and then use it under Windows (Most people who are considering a 7950GX2 are probably worried about gaming under windows anyway.)

And honestly, as long as you can stick that card in your Mac and not have it blow up, we will eventualy have drivers. Im sure without a doubt, we will either have offical real drivers, or hacked ones.

http://www.apple.com/macpro/graphics.htmlRight now the ATI Radeon X1900 XT card is offered as a $499 kit, and the NVIDIA GeForce 7300 GT as a $149 kit at the Apple Store as single line items.

They have offered upgrade video card kits and low end Apple OEM cards in the past, but usually not the cards people wanted.

Usually it was a more expensive ATI Retail Kit that you needed to order.

Let me sum up this thread for a sec..... I find this discussion pretty interesting, and really want to know what will work, and what not.

- The standard grfx card in the Mac Pro is below par.
- Best "bang for buck" card for in the Mac Pro is the X1900 XT. Quadro is for 3D modelling pro's etc.
- Best PC single gaming card is the 7950 GX2
- Newer PC grfx cards support EFI
- But will the newer PC grfx cards work in a Mac Pro? Is there only a driver issue, or is the MB not supported, or... any other reasons?

I wonder who will be the first to try a new PC grfx card in the Mac Pro. :cool:

Will graphics cards from the Mac Pro work in the Dual-Core G5 Power Macs? NO.

I'd consider it more like comparing a Ferrari to a Rolls Royce. Totally different markets.

While there is a chance that it would work, you wouldn't get the full performance in OS X. Why? Because OS X drivers do not support SLI. Even though this is 'SLI on one card', it still uses nVidia's SLI technology, and needs SLI support in the drivers. My guess is that if it works at all, the OS will see it as two video cards.

So, best case: It works, but is slower in OS X, so you can use the one card in both OSes. Worst case: It doesn't work at all in OS X, and not even in Boot Camp/Windows because of the EFI firmware issue.

We won't know for sure until someone tries it.

I dont think your simple mind understands...


it has nothing to do with chipset... it is just plainly about system incompatibility. if you read any reviews or anything about the 7950gx2 it is simply a VERY picky video card.


The website i showed you are mobos that have been thoroughly tested to be able to use both GPUs and use them properly. Of course there are other mobos that is able to support the card but might not use it properly. For example I have read on other forums where the card is only using one GPU rather than two, to render images.

Barefeats has been around for donkey's years. They do their own tests and generally know what they're talking about.

Before they posted that information I couldn't really see how Apple were going to stop people from adding a PC card with the same chipset. Looks like they've still got us over a barrell with VGA cards :(

If it is possible to install a 7900GTX under windows in a Mac Pro than it is only a matter of time when it will be possible to get this card also working under os x. Maybe we only have to edit the device id in the os x drivers.

ROM size won't matter, unless we have a firmware to flash to it. Apple doesn't have a 7950GTX card in their lineup, so there is no way we'd have the Apple firmware to flash to a off the shelf 7950GTX. You can't just take the 7300 GT rom and flash it to any other type of card. The reason I was trying to flash the XFX 7300 GT was because it is the same card as the apple one, basically. But I wouldn't even dare try to flash the 7300 GT rom to my 7800 GTX, even if the 7800 GTX had a 128k rom.

Why can't ATI and Nvideagive their cards less confusing names? How am I meant to know the difference between the X1900XT or whatever is called, and the Quadro FX4500 and the X1600 and the 7300 etc etc?

Why can't they just call it the ATI 1, and the one up from that, the ATI 2, ATI 3 etc:D :p

Thanks for the reply on the memory.

Newegg is the best, Newegg+Mac is even better.

Okay first of all the X1900XT is not ATI's flagship card, not even the XTX is, the newly released X1950XTX card with GDDR4 is ATI's flagship card and THAT card is faster and uses more heat/power than nvidia's flagship (7950GX2) as long as its not CPU limited (which means you really need a high end core-architecture processor).

The X1900XT is ATI's 3rd best card and outpaces the X1900 competition which are the 7900 cards, the 1900XT and 7900GTX are pretty close.

If I had to choose I'd go with a X1950XTX, its only 399$.

And any PC card works on Mac Pros running WINDOWS XP, as far as Mac OS X goes, thats tricky business.

One thing i can confirm for you all is the 7950gx2 WORKS in Winxp in SLI:)
and ver very well BUT when i boot her back in osx i get a kernel panic, i have read else where people are saying that there 7950gx2 doesn't give osx a kernel panic unfortunetly my XFX one does

Now to find a fix for the kernel panic

HAHHAHAHAHHAHA!
You're kidding right? NO!
The x1900 is NOWHERE NEAR as good as the 7950GTX

In fact, the 7950GTX is the best consumer card IN THE WORLD.
Actually in many tests the x1900 scored only 20 fps lower and even outperformed it in some. so the 7950gtx doesnt really blow it out of the water.:)

Wow, I thought most people knew that nVidia made the fastest cards in the industry :)

The 7950 GX2 has everything splattered (http://www.anandtech.com/showdoc.aspx?i=2769&p=9) especially when you pump up the resolution and throw some AA in.
No it doesnt... unless you call a 4 fps difference splattering. Your eye cant tell a difference in FPS above 80. so whether it is 100 or 300 it will just look the same. and the 1900xt only scored 3 fps lower than the 7900gt in SLI mode. HA.

ATI fanboy eh? SLI is meant for ultra high resolution as in Apple and Dell 30" screens with a huge number of pixels to push. At lower resolutions a single card can easily compete with two. There's nothing wrong with the 1900xt, its just that a 7950 GX2 >> 1900xt but then you have to bear in mind that 7950 GX2 costs >> 1900xt.

just a thought....

And knowing all this, I was kinda suprised that no one bought up the idea of dropping a 7950 into the Mac Pro with the intention of ONLY having it run under windows.
At this point, I see Mac Pro users not having drivers, or any other hacks avaible, a worst case scenario.
But if this did happen, why not just pop that 7950 into the 16x lane slot anyway, and then also have a 7300 in one of your 8x lanes (or even 4x).
They already tried it, and it works, but you have to switch displays to! So they are working around it now. They have copied the EFI files of the 7300 rom and put that in a pc 7800. Guess what, it boots into Os X as well! But you still don't have the appropriate drivers to get all the power out of it plus at the downside of the MacPro, you are missing the extra power that you'll need to give to the high-end graphics card. You can however take it from the second DVD drive with a hack/mod. The guys at strangedogs are working on it!!

Looking at some mac pro mobo pics, it looks like it's the right one.

This is *fantastic* news. They should try to get hold of the quadro rom and flash the 7800 with that. I'd much rather have a 7800 in there than the ATI card.

Not an ATI fanboy, I just think at this point in time ATI has the better card and better technology, next time it may be nvidia.

That's fair enough. I like the idea of having an nVidia card in there that you could always pair with another one later in the day. SLI is far more mature than crossfire and with the right drivers works on the Mac Pros (in Windows).

Yeah SLI is better than crossfire when they get that right then it will be pretty much even and just depends on what's better at the time.

Thanks for pointing that out. I ordered a couple of them myself. I will let you know if they are compatible. I have a spare PC Quadro 4500 with no way to power it. I have been waiting for something like this. I also have an open firmware version of the same card. I am hoping that one of the two can be UGA flashed.

Not sure who "barefeats" are as I tend to ignore the Mac "enthusiast" sites despite having been multi-platform forever, but plenty of people are running PC PCIe cards on the Mac Pro already, and its just getting started. Just search any of the PC enthusiast site forums and you will see it.

Apple may have enjoyed stranglehold control over their platform when they stuck with a PowerPC based machine that only ran their OS, but now that they have let the genie out of the bottle and released an Intel based machine that can boot XP, the game is over.

This is a sacrifice they will have to make for some increased marketshare for their hardware. The PC world is like the Borg. Utterly relentless. The Mac Pro is a *very* nice piece of kit. It's going to get hacked apart until it can be properly compared to a comparable PC running Windows XP and Linux with the same parts. Enjoy the ride! I know that Ill probably be upgrading my old tired G4 dual to a Mac Pro 3Ghz. This will be the first real investment in Apple hardware I've made in a long time.

The first thing I'll be doing is dropping my X1900XTX into it (Ill hand it down from my AMD FX62 system which will be moving to a DX10 vid card around the time I get the Mac) and installing Windows 2003 Enterprise.

If it uses a MOLEX connector, try using a regular PC power supply. Simply take the green wire on the motherboard connector and ground it out (jam a paper clip in the plug and connected to a black one). This will turn the power supply on.

Do this, connect it to the card, leave the case open, and THEN turn the mac pro on--in that order.

I did something like that at first then ran a power connector from the spare optical drive power connector to my 7800 GT. Now I'm just still stuck with having to switch the DVI connector when I reboot to get my 7800GT working in OS X.

Can someone clarify. The Quadro FX 4500 works just fine palying games, Maya,3DSM, Solidworks,etc. It is expensive but it does work. If you are a game designer I see this as a plus. Design the game, play the game. But that is why I want clarification.

so beenawhile since anyone has tried a 7950GX2 on Mac Pro
any new updates?
i still plan to get this card very soon.. and don't wan tto buy it only to have it not work with the mac pro and be unreturnable

as far as i gathered theres ppl on the net that claim ttha 7950 works in windows but screwes up OSX causes a kernal panic or something

so is there a work around it? or maybe possible to turn off that slot?

thanks
