    Hello guys...

    Is there any procedure to make possible the use of the GeForce GTX 480 on a Mac Pro?

    I know that some cards that aren't Mac Editions works on Macs. I think that it has something to do with the firmware or bios (something like that) of the graphics card.

    ( Forgive me about my english. I'm brazilian and I'm still learning. =] )

    Well... thanks anyway.

    If you run Windows natively (not via virtualization), then it's no problem.

    Otherwise, you may get into a situation you can't get it to work (OS X). To do so, you could try flashing the firmware (changes BIOS to EFI), but that means you need an EFI version of the card to obtain that firmware (and the card still may not work, as the ROM chip may not be able to contain it).

    The other method is via injectors. I've not looked into it, so I don't know if anyone's gotten this to work yet. But I presume not, as the cards aren't readily available yet, and are going to be on the expensive side.

    Why would you want a card that idles at 100°c and sounds like an Airbus during take-off in your Mac Pro?

    I'm waiting for an ATI 5000 series upgrade for my Mac Pro.

    Fermi's basically a joke anyway, you wouldn't want one in your machine even if you could.

    Oh no! Noise! How will the world cope?!

    I can't speak for others, but I buy based on performance. The computer goes under the desk where it belongs, not up on the desk to show how cool I am for using a mac, and I don't even notice it running even though I run the fans at higher speed than stock.

    Easy to say that when you haven't heard fermi's running at full tilt, they're very distracting. Not to mention the ridiculous power consumption and heat output (running a dual display setup idling @90c, that's pathetic).

    I suppose we'll see at some point, if we're lucky. I tend to prefer nvidia hardware over AMD, and I can't really care if it costs an extra $20/yr to run it. At least it'll actually handle OpenCL well once stuff takes advantage of that.

    That having been said, it's also "First in, best-dressed". I want a new video card, so the first decent one that gets to market for Mac at a palatable price is going to be what I get. 5800 series or GTX4 series, I don't care.

    what is the current mp's power supply rated at? Can it realistically handle the card anyway?

    It's 980w in the 8core, I don't know about the quad.

    Buy the OEM that makes it would provide drivers. Much like the GTX285 drivers for Leopard provided by EVGA.

    Each of the mini 6pin graphics card power connectors (PEG) should be able to provide 150W each (150W = spec anyway). The 8 pin PEG spec is rated for 225W (so if this port on the card draws more than 150W, it will damage the PSU and may burn the traces on the logic board).

    From what I've seen on the card, the GTX480 is rated to pull 305W (75W is provided by the PCIe slot itself). That leaves 230W to be supplied by the PEG connectors (6 + 8). So the MP's PSU should be able to provide it (assuming it meets specification, and not sort-of :eek:; it does happen :().

    GTX rumors overblown.....

    "Why would you want a card that idles at 100°c and sounds like an Airbus during take-off in your Mac Pro?"

    This is a rumor spread by ati-fanboys. True it's a little warmer than ati, but it's also faster and has more features. The discussions are endless as the ati-fanboys like to twist everything, just so they can feel good about the gfx card they bought 6 months prior. Sure, if you own a new ati, there's only a small increase in performance in the GTX, so it's not worth it to dump the ati. But for those shopping for a new card, the GTX is great. And you would want one, especially on a 23 inch Cinama monitor. I've already seen demos where the ati drops to say 10 fps while the GTX is at closer to 19fps due to tesellation ehancements and other DX11 improvements. And I could see the skipping in the ATI. Not that ati is a bad card, but there are at least some advantages to this new GTX 470,480 set.

    Temps are closer to 46c and reach about 70-85c in gaming, closer to 75. But again, it is a little warmer than ati. If someone had a poorly ventalated case, and sits in a 85 degree room, the temps could get up to like 93c under full load, which is still ok. But reading random, word of mouth reviews, from people who actually bought the 47x, they keep saying the "heat" issue is WAY over rated. That along with the electric use issue. ati-fan boys were claiming it would cause you to go broke due to the electric. Fact is, an ati system needs about a 550 watt psu. The GTX wants a 600watt, about 50 watts more. Someone playing games 4 hours a day, 365 days a year (having no life), would end up paying an average of maybe $8 more for the entire year. If they can't afford that for a little more speed, they shouldn't be buying a high end graphics card and get a job. My 3.8ghz i7 pc with 650watt psu will likely handle it as I've already read about similar rigs.. Not sure if 4ghz will pull too much power, but I like 3.8 anyway.

    As for noise, it's also not a problem unless the fans get above 77%. There are tons of users reporting thier fans usually don't get above 60-65%. Sometimes 70%. But at that point, it's not very loud. But if someone has two or three issues working against them like bad air flow, perhaps doing SLI at the same time, hot hard drives, and it's very hot in their room, then yes, fermi can ramp up and get noisy. But most of the time it's not. Someone with a reasonable case and good ventalation won't have that problem. Is ati cooler? Yes and it will be harder to get it hot, but again the GTX "noise" thing has been blow out of proportion on the net. I really wanted the added features of the new GTX. But I almost ordered an ATI because of all the bad press given to the GTX. That's untril I dug deeper and found out people love to exaggerate things. So I ordered one. I figure if it really sucks, I have a month to return it. I doubt it will.

    As for dual idling at 90c, as DesmoPilot mentions, that was an isolated case that happens only when you have dual monitor. They issued a patch for the profiles and they now idle at 45c or so as they should. Man, when rumors fly, they really go far, lol. But I only want ONE GTX 470, and it's an awesome card from what I've seen and heard. I saw a tesselation demo of realistic water and terrain (google it), and the ocean looks like a video of a real ocean instead of a game. It's incredible. Only a few games use that, but it's a nice feature to have. As for it not being available for mac, THAT is just a disadvantage of that platform. They always get everything later, or never and have to "wait" as rassert mentioned. Some claim it's not true and they can do everything etc, but in reality waiting sometimes goes with the territory. That said, I'm no longer worried about the GTX and glad I ordered it. I'll see how it goes.

    OK, here are a few facts for those not well informed. The GTX 480 is on par with the HD 5870 (the 480 winning in certain synthetic benchmarks and NVidia designed games like Metro 2033), the 2GB 5870 closing the gap between certain apps the 480 outperforms it in. The HD 5970 CRUSHES the GTX 480, the GTX 480 using MORE POWER THAN A 5970, as well as getting hotter and almost the same price. The GTX 480 is the only card where techspot has described the power consumption to be "truly terrifying". If you want ultimate performance, with a card that doesn't need its own power supply or operate @ a temperature akin to the surface of the sun, get an HD 5970. This is not fanboyism, these are the facts, the community at large supporting me concluding the GTX 400 series to be a complete flop. Any earlier reviews which showed the 480 to be beating the 5870 were without ATI's 10.3 drivers, which increase performance quite substantially (it wouldn't surprise me if they were waiting for NVidia to release their 400 series and then to crush them).
    It is also noteworthy that NVidia has essentially been forced to release the 400 series simply because they had to release SOMETHING to compete, and are actually selling them @ cost price. ATI can thus lower their prices even further, making only to the die hard NVidia zealots the 5870/5970 a poor choice.

    sorry waves, you don't compare the 5870 to 480GTX when it's the 5970 that is in the matching price range. And versus that card, the 480 loses big time. It's not a bad card, but claiming it's the best alternative out there is a far fetched fantasy.

    I keep my mac pro on my desk for 2 reasons: 1) easier accessibility to rear ports, 2) in my experience putting a tower on the floor clogs your machine with 10x more dust. I have had my mac pro on my desk for almost 3 years and there is a very thin layer of dust inside. I have seen more than one person in this forum complaining about getting their graphics cards clogged with dust which has resulted in display artifacts.

    Fermi is a bit of a failure bro, get over it. The 470's not bad, but the 480 is just too power hungry and hot to justify its small performance gains.

    All of this chest thumping and flag waving forgets the important fact that this is a Mac forum.

    So the only meaningful comparison for us is going to be:

    WHO RELEASES MAC EFI ROM AND DRIVERS FIRST.

    With an 8 month lead, my money is on ATI 5870 coming for us....oh, at least 6 months sooner. Just a guess.

    So until we have BOTH as options to compare in OSX...WHO CARES ???

    will try this soon

    I'll stick a 480 in my 08 Pro at the weekend, but as per Cindori's comment, I do not expect much life except in Bootcamp. I am going to power externally, and see just what goes on with Netkas and CoreVidia injectors. Without the drivers my guess is screen of death/kernel panic, but I suppose there is 1% probability of something new with 10.6.4, if I can get my paws on it. We were a bit disappointed yesterday when we stuck it in a regular PC, getting CUDA perf barely better than a 285, so my initial goal is to see what happens under Bootcamp.

    Here's something which purely illustrates the essence of the GTX 480.

    YES: GTX 480 up under bootcamp, 2008 Mac Pro

    So after some faffing I can report a PNY GTX480 is up and running on my 2008 Mac Pro, under bootcamp for now, with XP32.

    Power: I am using an external Toughpower 1000W ATX PSU with lots of 8 and 6 pin PCI connectors to supply the necessary 6 and 8 pin power. As usual the motherboard power is shorted on the green and black slots with a paper clip to get it working without being connected to a computer.

    The main card is a Mac edition GTX 285.

    Bootcamp drivers usual nightmare, with Windows new hardware wizard (retard?) fighting with the drivers on both the PNY CD and the downloaded NVidia ones. Eventually got it up using manual location and ignoring some rubbish about things not being certified.

    My main thing is CUDA programming, not games. I have to do a systematic check, but the thing we all try first is the n-body simulation. Here are the comparisons with the GTX 285, done side by side with nbody --device=0 and nbody --device-1 from the command prompt.

    285: 498 Gflops single precision
    57 Gflops double precision

    480: 561 Gflops single
    116 Gflops double

    My devicequery is reporting ONLY 1.40 GHz for the 480 against 1.48 for the 285.

    More or less as expected, get grey screen of death under 10.5.8 and under 10.6.3 I get the system up but with the card only just recognized, with sysinfo reporting the PCI ID correctly as per screen shot below. I have a mixture of CoreVidia and Netkas injectors in there to manage the PC 285 I just took out, so this is not terribly controlled.

    Anyway, it might help readers to know the hardware is perfectly capable of running this card, so it is a matter of OS X drivers now, and perhaps waiting for a full Mac version.
