good news :)
So if the 8800 would be supported by OS X the world would be perfect...
 
just an update for you guys!
i got my welovemacs.com $30 PCIe Power Cable!!
so for a a cheap $60 i got 2 of them haha
installed them right now and everythings working great and it's nice and clean!

the bad news... it didnt' solve the whole using both the 8800 and the 7300 at the same time! boo so i still gotta do the swap thing for OSx
but oh well it's much nicer now and more silent casue i can actually close the case now
 
btw. have you tried ALL the free PCIe Slots for your 7300. I´ve read in a german forum, that a PC Card in the first and the "Mac"-Card in the 4th slot is working...
 
Aion. Thanks.

Could you by any chance provide me the link for these cables ? I cant quite find them on the site.
 
But did you try..

i tried ahving the 7300 on slot 4 and the 8800 on slot 1 and no go
i didn't bother trying the 7300 on sloth 2 and 3 casue there at 1x so i thought no point

and for thoese that want to buy the cable

http://www.welovemacs.com/9227128.html

Did you try the 7300 in slot one (the one it was installed in when you got the Mac Pro) and the 8800 in slot 4? That is the configuration that is supposed to work. Also, do not forget to assign those 2 slot 8 lanes each using the PCIe utility.
 
i can't do that
casue the 8800 takes up 2 slots so the only way for it to work is on slot 1
also it needs to use 16x for it to work also

i have at the 8x for slot 4 and 16x on slot 1
 
aiongiant i got a question. what all did you have to do to get your 8800 to work and how did you do it. im new to modding
 
I have a mac pro and the 8800GTX card. I have my system set to boot into windows xp. I pulled the 7300 card out and placed in the 8800 in the same bottom slot. I have an external power supply that's SLi ready and I can confirm 12v at the 6 port cables I plugged into the 8800 card. When I boot the machine everything works perfectly but I can't see anything on the screen. I know it's working because I let the computer boot and i type my password in and press enter ( this is all with a black screen) and I hear the windows music. So i know it's all booting up properly.... what am I missing that I dont have video display? and yes the monitor is plugged into the card and it has power. I get the same thing disabling the video in device manager as well. any help would be appriciated.
 
Just a quick reality check -

The 8800 just became available - it is totally unsupported by Apple, and putting one in a Mac forces you to give up OSX as long as the card is there. The card manufacturers like BFG don't support this card in the Mac. There are no official or unofficial drivers for OS X. The Windows drivers are early versions that will doubtless see much revision to iron out bugs and performance deficiencies. It also needs two power cables which, as you can see from this thread, means either a jury rig or a few extra parts from newegg, plus noticably higher electric bills and brownouts every time you boot up your computer.;) :rolleyes:

The "Titan" drivers may or may not provide a solution of sorts but bear in mind that these are not optimized for any card in particular and therefore will not necessarily provide good performance. A lot of development is still needed and it won't happen over night.

If you have a Mac Pro and

- want the 8800 for bragging rights

- want to tinker with the "Titan" drivers and the 8800 series

- don't mind giving up OS X and running Windows all the time or

- don't mind constantly swapping video cards whenever booting into a different OS

Then go ahead and get the most powerful video card in existence at the moment. Otherwise an OEM Apple X1900XT will give you most of the performance you could desire and will work in either OS X or Windows.

I hope people keep tinkering with this, but keep in mind this is well beyond the state-of-the-Mac...it will probably be several months before we get new video cards (and thus, Apple ROM files to hack). Don't expect an elegant solution to show up anythime soon.

Still, it's nice to know that Mac owners these days at least have the option of putting the latest high-end gaming cards in their Mac Pro...even if it isn't officially sanctioned.

I really have to wonder if its all worth it for a that additional 20 FPS....seriously. Games on the x1900 XT are already over 60fps on average....and to have to sacrifice OS X for it? No thanks.

Not at 2560x1600 they're not, at least no modern games with good graphics. Sure, you could argue that World of Warcraft will run perfectly at that res, but then again, it's graphics aren't cutting edge. Try running F.E.A.R at that resolution with some high detail options (not all). It would choke.

Not to mention DirectX 10 games coming soon. The x1900 doesn't even support DX10 shaders to begin with. The _very_ least Apple could do in the next rev of Mac Pro's would be to add x1950XTX as a BTO option. However, most would agree that it would be advisable at this point include a DX10 card, since with PCI-Express 2 on the horizon, who knows how long will it be before these cards with EFI are no longer made (remember the cards for AGP G5's?). After all, it's a BTO option, who cares? Those that don't want it, don't buy it. But it's silly to leave it out in the first place for people that are willing and able to add it to the configuration.

Here are the power draw numbers for the current cards...

Graphics card Video SDRAM Power usage

Nvidia GeForce 7300 GT 256 MB (GDDR2) 32 W

ATI Radeon X1900 XT 512 MB (GDDR3) 132 W

Nvidia Quadro FX 4500 512 MB (GDDR3) 110 W

Where did you get those numbers from?
 
why buy a mac and then use windows?:apple:
It has been said several times before.

1. More (and recent) games are under Windows
2. The Mac Pro is a very good workstation for the price
3. Yes owners of ICBMs can run both OS X and Windows...the right tool for the right job - no worshiping or cultism required.

If you don't like or understand it, too bad for you.

Anyway back to the actual subject.

I have a X1900 XT in mine, which is both extremely loud under load and not powerful enough at the 30" native resolution. Setting aside the minor cabling stuff, would this work?

slot 4 (8x) : 8800 GTX
slot 3 (1x) : empty
slot 2 (1x) : empty (until the X-Fi PCI-E comes out...for WinXP only I guess)
slot 1 (16x): X1900 XT

When booting OS X I would connect the monitor to the X1900 XT and for WinXP I would connect it to the 8800 GTX. I suspect that OS X will try to initialize the 1st card (in slot order) and ignore non EFI-compliant cards.
 
i think the 8800 requires a 16x slot no?

if not i don't think it will work either way...
mainly becasue if a 7300 and a 8800 won't work together a stronger more powerful card like a x1900 will not work either

has anyone have any new progress on getting the 8800GTX to work under OSX??
 
hi ive just been reading the forum and i was wonderng what is titan. it mentioned in the first 2 pages. IS it a driver that allows you to use a pc card in osx. Sorry if this is a basic question but i cant find it on the internet and the link doesnt work. Than you
 
From the Titan Wiki:
Titan is a registry key setter kext for the new 10.4.8 NVIDIA kexts. What does this mean? For the Apple NVIDIA kexts to work, several values must be set correctly to get vanilla[unauthorized] cards to work with it. This kext sets those values, allowing the user full QE/CI/OpenGL, as well as resolution switching and refresh rate changing.

If you could tell me what are the benifits and down sides, can a 8800 be used in mac osx using titan and is it a challenge to do it? what would i be givng up, and does anyone believe that this may soon alow anyone to take a regular pcie card and put it in a mac
thanks

Read through this thread and you'll find the benefits, downsides, and if the card can be used in OS X (short answer - no). :)
 
power cable.

regarding this special power cable (p/n 922-7128)

just ask your mac dealer (not online sales).
This is not a part that is on sale in apple stores or online, its a service part.But I had no problem ordering mine.You just have to use that old fashioned communication skill called asking":confused:

it costs 9 euro's and is normally there the next day. (if they dont already have it in the back room)


btw, that linked company is asking over 3 times what apple sell it for.What a rip off !:mad:

Well sure, you could try 'asking' someone...

But why do it the easy way when you can MAKE YOUR OWN muahaha.
 
Anyone want to buy my eVga 8800gtx 768MB blah blah card to try this with :D

I've got it in my PC but since I got my MBP I've decided to part out my PC. Just testing the waters...I could put this in marketplace but I figure I'd mention it here since this is the 8800gtx thread and all ;)

PM me an offer if anyones interested comes with everything but the box I've had it in my PC for just about a month card has full warranty etc;
 
Question, When you bought the GTX, before buying the power cable, you were able to still boot it up using macpro's powercable correct?
