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

I got a XFX 285 GTX running in my Mac Pro 1,1 but it is only reporting 512MB of VRAM in System Profiler.. Is there something I can do to correct this or is it not going to effect the performance at all and it is just a display error and the computer is actually going to use all of the 1GB that is physically there?

How did you get that card working on your mac? I'm curious.

Download and install this: http://mirror.netkas.org/Enabler_for_Nvidia_and_multiple_ATI_cards.pkg.zip

Open the expansion slot utility and set slot 3 to 4 lanes and slot 1 to 16 lanes (its the second option on the list). Then reboot.

Now shut the machine off and install the 8800GT in slot 3 and the 285 GTX in slot 1 and put power to both cards. I used the two cables coming off the board and a 4pin molex adapter from the second optical drive power. Then boot up and it just works.

OpenGL Extensions Viewer does report the whole 1GB of VRAM so the issue in system profiler is just cosmetic. Photoshop recognizes the card just fine.

I cant wait to get a little bit of Bad Company 2 in tonight.
 
This is almost a perfect howto, short sweet and to the point. HOWEVER =) I have an ATI card that came with the system. Will this work or do I need the 9800GT? Can I use somebody else's Image from a 9800 (do you have one)?

I completely appreciate your input.

I believe you can use a 9800GT but I am not sure. From what I have read using an ATI card will kernel panic at boot up.

I dont have a 9800GT image or much information about that. Sorry.


Now I have a question for someone who might know... has any one tried powering the cards using a Y 6pin pci-e power cable? Currently I have it running using a 4pin Molex to 6pin adapter but would love to able to just use the Y cable and still be able to use two drives. I am only using the 285GTX so I dont think the 8800GT helper card would be pulling much power at all.
 
I have 4 different Apple 8800 GT ROMS.

One EFI-32 and three EFI-64.

The EFI64-3 is the newest ROM and this worked in a Zotac 8800 GT.

Included is a PNY 9800 GT 1GB EFI-64 ROM that was provided to me from a working card but I haven't sent my card for modification yet so I haven't personally tested it.

I know it's a thread about software solution, but since my soldering skills are pretty good I wanted to try the hardware method, but I cannot find an efi rom dump for the GTX285 anywhere on the web. Would anyone be so kind to send it to me or upload it somewhere? I hope it's not against forum rules to ask.
 
Will a Mac GTX285 work on a 2006 Mac Pro? I've read about having to stick another card (such as a 8800 or a 7300GT) on another slot for it to work.

To answer myself - yes.

This kind of answers the question I was about to post. I have a late 2009 Mac Pro dual quad-core with the ATI 5870 or whatever it is.

I am running bootcamp on a seperate drive with no hassles (using the reference ATI catalyst suite with no probs - 40-70 FPS in FSX and over 100 in CoDMW2)

My question: I have a GTX 295 sitting in my sad old PC, the PC that hasn't been used since I got BootCamp working so sweetly. Can I stick it in the Mac? On its own? I don't want two cards, and you say it works in 10.6.x

Howso? With no flashing? With the Mac 285 drivers? Please tell!!

Thanks :)

Yes... I have a 2006 Mac Pro (1.1) and I have a XFX 285GTX in it and yes it does require another nvidia card in the machine. I have a 8800GT in slot 3 and the 285GTX in slot 1.
 
GTX 295 in Mac Pro 5,1 working

tsuki said:
Hey there guys.

After much sweat, tears, and even a little bit of blood (nicked my knuckle on inner casing), I have come to a very frustrated dead end. Sadly, I am more noobish than experienced on these things, so have not been able to sort my configuration out, although some of the info on here goes over my head, so anyone helping out would be great.

I have a 4,1, 2009 mac pro. I also bought an EVGA GTX295. I thought I had all the info needed to install it but I was wrong. I attempted mroy's setup which hasn't worked due to me using Snow Leopard (6.2) rather than Leopard.

When I install using the GT120 as my helper in slot 3, I have no boot whatsoever. Black screen. I actually presumed that even though it might not boot into OSX, Windows would work under Boot Camp. So very wrong.

I have also attempted a Hackintosh method of installation involving what seems to amount to me as getting a HEX device name for the GTX295 to put into the boot.plist. Sadly, unlike the Hackintosh, I cannot even get into OSX to work this. I have attempted booting from the GT120 with the GTX295 also in place to get the hardware code as it were. This also didn't work.

My apologies if this has been figured out and posted, I've read the whole of this post and many others! I think I just don't have the technical knowledge to extrapolate the info I need.

So:

Mac Pro 2009, Quad Core Nehelam.
EVGA GTX295 Co-op.
Snow Leopard 10.6.1

If anyone could help me I would be so happy cos I'm ready to hang up my spurs after having spent a massive chunk of my life attempting this!

Cheers guys.

Hi,

Just for reference my Gigabyte GTX295 1.8 GB is working in my Mac Pro 5,1 together with a GT120 with Snow Leopard 10.6.4 using the Netkas injector. I have only tested it with CUDA as I have an LED Cinema Display and so use the DisplayPort on the GT120 and I only need the 295 for running simulations. In System Profiler the memory is reported incorrectly as being 512 mb, however CUDA reports the correct memory when running deviceQuery from the CUDA SDK.

Installation was very simple. Everything booted normally after installing both cards and all I had to do was install netkas' injector.

It was important to put the gt120 in Slot 3 as has been mentioned many times already, otherwise I would get a kernel panic when running cuda programs.

Oh and the Mac Pro 5,1 runs the 64bit kernel by default so had to change to the 32bit kernel as netkas's injector is 32bit only as i understand it.

Thank you netkas and all contributors to this post!

Cheers!

PS - Comparing CUDA performance between Windows and MacOS revealed that the GTX 295 was running >50% slower on the Mac (430 GFlops vs 200 GFLOPS for nbody SDK example). Following advice from other posts, all I had to do was add a new sub-section in /System/Library/Extensions/AppleGraphicsPowerManagement.kext/Contents/Info.plist under Mac5,1 with the GTX 295 deviceID/vendorID.

Performance is now at 380 GFlops which is still substantially slower than windows. However, I think this is related to the CUDA implementation on MacOS, rather than another configuration problem, as the GT120 also shows a similar slowdown in MacOS compared to Windows.

sship21, how did you solve power supply for GTX295?
Click to expand...

I have the GT120 in slot 3 (actually the 2nd physical slot) and the GTX 295 in slot 1, having removed the standard Radeon 5770. I used the 6pin to 6pin Pci-e cable from the Radeon plus another 6-pin/6-pin cable and a 6-pin to 8-pin adapter cable off ebay and amazon respectively. I then connected the GTX295 to the motherboard. The GTX120 does not require extra power so I used both power sockets on the motherboard for the GTX295. Just in case I get a another GPU, I also bought 2x SATA to Molex adapters, to use with the Molex-to-6pin/8pin cables that came with the GPU, which will allow you to use the SATA connecters from the harddrive bays for power.

Cheers
 
BFG GTX 260 + 2600 HD on MacPro 2008

Anyone has succeeded with the gtx 260 using an ATI 2600 HD and Netkas injectors?
 
Just for the heck of it.

Current Injector does not work with First Developer Release of Lion


EDIT: Mac OS X 10.7 boots by default into K64. Booting into K32 makes netkas injector work!.

Just installed GTX295 + 8800GT in MacPro 3.1. Working like a charm!
Any one knows how to slow down cooler of the GTX 295 cause my MacPro is now noisy as a PC? :)
 
My MacPro won't boot from the last update of 10.6.7 with GTX295. Panic screen is the only I have. When I remove power for the GTX OSX boots normaly. I tried to install fresh system, working until last update.

Anyone have idea how to fix this?
Thanks!
 
I just picked up a GTX 295 and it works under SL, but I can only get it to work under 10.6.0. As soon as I install a combo update it stops working. Specs are in my sig but instead of the GTX 285 its a 295.

Any ideas? Thanks in advanced!

Hey Rominator,
So my ATI Radeon X1900 XT is on it's way out and I have to boot multiple times before I can get any of my monitors working. This is obviously accelerating my need to replace it and figure out the future DaVinci Resolve issue. I like the idea of spending $600 for a couple video cards instead of $6500 for a new machine. So I am going to try the injected approach very soon. I wanted to ask specifically what GTX285 you were running? I'm assuming the 1GB version from EVGA? If the 2GB can work in the Mac Pro 2,1 I would love to get that one instead?
I had a crazy idea this weekend that could solve my concerns. If this setup with both cards running in 8x mode for working in Resolve works...then it would be sweet to setup a switcher that is fed by both video cards. That way when running DaVinci Resolve I could switch over to using the 8800GT to run the monitors and then in the Expansion Utility switch the cards into the 8x, 8x mode (to accomodate the Raid and Kona card that need to run in the other slots at 4x). Then when I'm done working in DaVinci flip the switcher back to running the monitors off the GTX card and use the Expansion Utility to switch the GTX into 16X mode and the 8800GT into 1X mode (that way the other 2 slots stay in 4x mode) and I have a power house for After Effects and 3D work. Any thoughts on this idea? Can the whole setup work with the 8800GT running in 1X and the GTX in 16X with the monitors hooked up to the GTX? Thanks again for all the great info.

Hi,
did you do the GTX285 / 8800GT upgrade for your Mac 2.1 to use Resolve? I also got a 2.1 8-Core MacPro running SL 10.6.8. I can buy a new Mac 5.1 or update only the gfx card.

Is Resolve really working well with this configuration?

Kindly,
fm
 
I got the 285 installed in my Mac, but in Resolve/Premiere the Mac doesnt recognize any Cuda card.

PCIe settings
Slot 3: set to 4 Lanes - ATE x1900 installed
Slot 1: set to 16 Lanes - GTX285

The system profiler shows the card with an installed driver (ROM-Version:netkas.org), but its not showing the VRAM.

Anybody got an idea, why the card isnt working correctly? Monitor output i only get through the ATI card. If i connect the DVI to the Nvidia, the screen turns black.
