PCs GTX285/275/260/295 working in any MacPro....

STranger and stranger.

I'm gonna get a 7300 and see what's up with it & GTX285.

Awhile back I played with Quadro 4500 EFI and PC BIOS 7800GT.

In certain slot mixes, the 7800GT would function in OSX. The behavior had been reported here but with a 7300GT used in conjunction with 7800GT.

So I will grab up a 7300 in next few days and replicate. We'll know if it is a 7300GT issue or a Mac Pro 2,1 issue.

But really glad you got it up and running.

Did not seriously expect slot swap to work....hmmm.

On your benchmark - nice to see but two minor points

1. If you can run at 1920 x1200 with those settings you can compare with several others posts.

2. If you run the OpenGL bm twice you might see an improvement in the 1.1 figure - some of us have notice the Mac version card throttling down and only coming to life by the end of that test.

Hello

I have an Asus GTX285 PC I'd like to use my new Mac Pro, the problem is that it takes very little time using Mac computers and are not nor do I install. Anyone can explain in a simple manner?

Another thing I do not understand is the issue of speed link. What can affect the GTX2XX PC graphics card operates at 2.5GT / S instead of 5GT / S?

Thanks and regards

The driver fix worked great! Thanks. I put the 7300 in slot 1 and the 285 in slot 2. I used the expansion slot utility to set slots 1 and 2 at 8X. Everything works great. I do have to connect the monitor to the 7300 momentarily and then back to the 285 to get the proper display.

Ditto.

I can boot ON the 285 just fine, but its "another" piece of the desktop that way.


I cant get to the dock..os boot on 7300, then move to 285 and then its a root display with the dock/etc all just fine.


The tests I ran, are the limit of the monitor Im using on this.

My good monitor is at the office on the other Mac.

Now if I can figure out how to get Windows 7 to boot from the 285 in slot 2, I'll be set.

End up i got an palit GTX285 1GB version. Waiting for my MacPro back from service at apple service center. in the mean time, hoping i can find more information about the slots for gtx285. is it a must i need to put the card on Slot 2 and mac efi GT120 card in the first slot, because i don't want to waste the extra slot above the slot 1 for the air ventilation.

You should try first with 285 in slot 1 and GT120 in 3. If that doesn't work try GT120 in 2. As a last resort I would do the EFI card in 1. We still need to figure out if this is some limitation of 7300.

Make sure you install the F16 package AND Netkas package.

DON'T use my "driver fix" on a 3,1 or 4,1 Mac Pro !!!

Keep us posted.

Ok campers...GTX285 in my 2,1 Pro..but in Bootcamp?



Ok..works fine on my 2,1 MP, with the kext insertion, etc.


Now..any hope for getting it working in bootcamp?

Although I have 3,1 Pro, I had my pc cards working under bootcamp (xp) long before I go them going under OS X - just get the right Nvidia drivers for your version of windows.

does anyone got the gtx 295 working on a mac pro?

Ya..solved it.

Had to muck around with the multiple monitor settings a bit, but finally got er going.

Nobody has done it YET.

Here's your chance to help the community !

Dlary's 7300 issue FIGURED OUT !!!

Will go check right now.

10.5.7, yup
Will try Slot1
No manual edits at all.

===

Moving 7xx to slot1, boots. The Expansion slot utility loads..and sees the 285. Yay!

Now..it seems that since I cant ue the 285 in a x16 slot, that Profile #3 to make slots 1 and 2 both x8 slots..would then be best., or even config option 4.

===

Weirdness.

The 7300GT I ordered has arrived and it works fine in slot 3 of my machine, in regards to booting the GTX285.

It functions just like the Quadro 4500 in that you need to briefly run display from 7300 and then the GTX285, otherwise it is "Second Display".

As far as why this works for me and not SPEEDTOY, I put forth the following :

1. Mac Pro 1,1 vs 2,1...somehow the slots/addressing changed a touch?

2. ROM revision of 7300GT. Mine shows 3008. I opened up the 7300GT FIrmware Update. It appears to be updating Rev 3004 to Rev. 3007. So it seems that there are 3 possible ROM revisions for 7300GT. Perhaps 3008 is needed for proper behavior?

3. Slot 1 needs to be @ 16 Lanes and Slot 3 needs to be @4? Give it a whirl....

Good news is it seems that for Mac Pro 1,1 it is possible to run a GTX285 in conjunction with a 7300GT (most came with these already). Again, this requires Netkas find injector package and the drivers, but NO Flashing or soldering. And since the 7300 requires no additional power, there are enough plugs available to use cards like this.

EDIT: FIGURED IT OUT !!! I did the reverse of my Number 3 above, I set my Slot 3 to 1 lane instead of 4. On next reboot I got a Grey Boot from 7300 which went into kernal panic. So, apparently the second Nvidia card with EFI needs to be @ 4 lanes minimum for Netkas trick to work. All Dlary needs to do is use Expansion Slot Utility to set Slot 1 @ 16 and Slot 3 @ $ lanes. Then the 7300GT will work from slot 3 and the GTX 285 will work in slot 1.

Maybe I missed it between all the post, but is there a PC card already with a size big enough to fit a EFI, so we can avoid using injectors and stuff?
The GTX 285 still is not on the Dutch store site :-(

Assuming you are talking about the ROM size, I do not think any of us have found a PC card shipping with a big enough chip. I had wondered if the EVGA cards might so that EVGA could manufacture just one 1G card but that has not turned out OK.

The injectors are very good if you already have other Nvidia card in there.

 

[tezro]

Well, that's the thing. I don't want another videocard in my system just to run another.

I emailed Apple in Holland last night if they can give a date or something on when the card comes available to Holland, since so many other countries can already order it.

 

[DLary]

Thanks for the help. I've got the 7300 in slot 3 at 4X and the 285 in slot 1 at 16X. Everything works great!

So none of the PC 285 cards can live alone in the machine so far, they always need a "helper" ?

Great news...we found another piece of the puzzle....."helper" EFI card has to be @ 4X or higher to work....1x leads to kp.

helpful for future adventurists...especially as many 1st Gens already have a 7300...all they need is a GTX285 !!!! (and a few driver installs)

great, since mine i cant adjust the speed of the lane due to the latest modal seems they rip off the capability, well my slot 1 and slot 2 is x16 and 3/4 is 4x. cant wait for my mac pro to come back(from service due to logic board failure) and test the 285.

Installed GT120 + Palit Gtx285 1GB version. Boot fine, games,benchmark all fine but CUDA failed. Any idea guys?

Used netkas latest injector + latest drivers for GTX285 @ nvidia website.

EDIT: All Fixed and run fine. Have to install the latest beta CUDA kext 2.2.1 (2.2.0 from the web is not working) from the nvidia web.

Seems to be. As long as the ROM-chip size isn't big enough to carry a EFI sized thingy, we can't use it alone.

I contacted Apple in The Netherlands and they can't give me a date for when the card appears in the Dutch Apple Store.
No clue why The Netherlands is always so behind.....
It sucks!

 

[MacVidCards]

Great option for 1st Gen with a 7300GT

Just want to reiterate, that as far as using the injector to run a GTX285, we 1st Gens have an advantage over the later machines. Ours typically came with the 7300GT, which is needed with Netkas package to enable GTX285.

So, if you have a Mac Pro and a 7300GT, all you need is a GTX285, the power cables, and Netkas' package.

Then you too can have the FASTEST Mac GPU ever.

 

[Spacedust]

What about GTX250 ? Will it work in pair with 7300GT ?
