If I connect it to the old video card it works fine. Jun 6, 8: You will get no output on a PC graphics card until the driver loads the Login screen or the desktop. Yeah I'm given it long enough I think, and when I plug the monitor lead into the old graphics card it works straight away.

Would the monitor not turn on until the desktop view? I thought it would of still turned on with a black screen until the desktop? Jun 6, 9: Like I say I've given it plenty of time and still nothing happens, when I keep the mac on and swap over the monitor it comes on straight away. And any pc card should work just without a boot screen?

Jun 6, Without EFI firmware, it does not show anything until the driver is loaded, which is at the desktop if you auto-login, or the login screen if you manually log in. Thats exactly what I thought before I bought it and the person I bought it off is positive it's working fine as he was using it in his pc before sending it to me. It shows up in system information as being there in slot 1. I've check the extensions folder to make sure it does have the right drivers built in and it does have them, so can't understand why I'm still getting no signal..

I can't even go into Safe boot or system recovery because it won't do anything when you press the commands. Wireless keyboards can be used, but are much more cranky. With a PC graphics card, the driver is not loaded, so nothing appears on the displays on that card. I've tried many times and the only ones I can do are disk utility and reset PRAM at the start, I've read that macs can be installed without having system recovery with it and I'm guessing that's the case with mine as you can't reinstall my os from recovery cause it wasn't supposed to have el capitan on mac pro and it's a piker boot version.

My keyboard is already connected directly to chassis and is wired, so that shouldn't be a problem. So if you can, how do you load that driver for the card?

Test Systems: See also reader feedback below from Pro Apps users Personally I'm inclined to stay with the GeForce GT for now, because game performance is important to me. In idle mode, the fan noise is very unobtrusive, much like the The fan did speed up a few times during the 3D benchmarks, at which point in was clearly audible - not nearly as much as the X's stock fan though. I did have the Mac Pro's side door open during the tests, and many of the benchmarks didn't have audio, so I think it wouldn't disturb me during gameplay.

I can't really say how it would behave with pro apps like Motion of Aperture, but I'd think the fan would stay pretty quiet. It seems to me that the 's fan speeds up earlier than the 's, and also slows down again sooner.

Then the fan would keep running at increased speed for a while. The Zalman VF www.

BTW, the is based on a 55nm chip, while the is based on a 65nm chip. As a result, one would probably expect the to be more power hungry and to dissipate more heat. I didn't measure this, but it can be seen in other reviews. All of them note that the uses less power when idle, but under load they don't quite agree with one another - it looks like it depends on the type of load.

If anyone knows any video tweaks to get rid of this problem, please let me know. How's performance playing back downloaded to local drive QT HD movie trailers? He later replied: I just downloaded the Star Trek P trailer and it played as smooth as melted butter. Thought it might be a flash issue. And then, it's only once in a while - some White House weekly addresses are stutter y , and others aren't.

Thought it might even be a temp issue, but the Accelero keeps it warm but not volcanic. Not the fault of your hardware at least. Otherwise you'd see it consistently in other similar tasks that didn't rely on a remote data source. Mac Pro Specs: This thing definitely generates some heat out the back, but I love it. The fan only spins up when playing a game in Windows. Smooth frame rates at x, but had to lower the anti-aliasing setting a bit. The fan gets pretty loud when gaming, but that's expected, since the card is under some stress.

Temps have been pretty good too, hovering around 75c when gaming, around 50c when idle. I started the following thread detailing my issues with my original card, and how much better the replacement got. A lot of people have replied in that thread about their experiences with Accelero coolers, so I thought maybe it would be some interest to others. The thread still has some activity from time to time. Also, I believe someone mentioned in the thread above that the fan speed control in the has a poor implementation, since the fan only uses 2 wires.

I think I probably just got lucky with my replacement one. Please bear with me, this lengthy but informative tale. Oliver and other early comments originally said the was better at Pro Apps and non-game apps than the GT, although reportedly COD4 runs faster on the than the GT.

Oliver also said in his original review here he chose the GT over the And like many Mac Pro owners, he bought the GT first as it was available months before the Mac was released. I had no great problems installing but the documentation was pretty bare bones. Although it recommended removal of bootcamp drivers for the old card NVidia GT and told how to do so, it said nothing about what to do as far as using the under bootcamp. Contrary to the great claims of subtle heat-based fan control, the sounded like someone in the distance using a chainsaw. Every little action from dragging a desktop icon or window, to painting a stroke in Photoshop CS2 caused the fan to rev up, and then subside quickly, and the fan made many times as much noise as any of the Mac Pro fans, which I rarely hear.

All of us Mac owners for years have been disappointed in driver updates literally none except for what's included in OS X updates - ATI and Nvidia released frequent driver updates for windows but on the Mac, there's literally none except for what apple releases In the mean time I was at least getting very good performance in Photoshop and in OS X games even with settings way up; for simpler games, maxed out. When I was finally able to get in touch via email with ATI, I was provided with a link to some completely unsupported "beta" drivers for bootcamp.

Did you try the standard releases for Windows? A windows savvy friend helped me download and install some regular PC drivers which installed in a folder called ATI. Trying to register the card to get warranty service on the ATI web site was ridiculous because there was no selection for the card in any tables, forms, or menus. The first time, the question would always be answered with a stock PC answer, regardless of the fact that I specified I was using the card on a Mac Pro under Leopard The second answer was unfailingly a pathetic echo of my question back to me as supposed acknowledgment that they understood what I was asking, followed by very little to help.

I have heard of similar experiences from others. After finally obtaining an RMA number, I was required to package JUST the card and pay to have it shipped to them, with no option to get a new card before sending the old one. The new card I received did not create the same fan noise or kernel panic problems and I haven't ever even tried to use bootcamp with it, because any changes in settings under windows XP seemed to exacerbate problems with the card under OS X.

The new I received has functioned fine from early August 08, to the present. About a week ago the screen once became badly distorted by dancing green pixels of the sort i'd only read about with Apple monitors having loose DVI plugs. Over the past few days my system has been having some mysterious problems with games and Photoshop crashing, which I thought might have something to do with cooling, as the front fan in the Mac Pro has been making an occasional clicking sound.

Yesterday I had 3 peculiar instances of being unable to wake the computer, or having the display an HP suddenly darken and go into sleep mode. And each time I hear the sound, the fan is slowing, as if there's something caught in it, though upon removing it, I can't find anything to prevent smooth travel. I also noted some comments about how cool the card runs. Some say the uses more power than the under load arstechnica. I'm truly sorry you had problems and for the typical standard support replies. It's depressing to still see the very few retail options for Mac graphics cards for many years now as well.

I still see an absolute bare minimum of information about the on the site after all these months. Since obtaining a replacement was such a hassle in the first place, I decided to deal with it myself by installing a 3rd party cooler knowing there was no way back. However I didn't realize until I had already installed it that the fan power connector on the was incompatible with the Twin Turbo fans, so I wasn't able to get them working.

I'm not sure if it was due to the lack of the fans working, an improper install on my part, or an existing fault with the As a result I wasn't able to do any gaming for some time while I mulled over the issue. And let me tell you, I severely regret not getting it in the first place.

I've very satisfied with it and it does indeed perform slightly better in Windows - I don't have any good Mac games to test. It's a shame since otherwise the could be a very decent card. His original mail on problems follows I have a Mac Pro. I've had the for about a month but the experience has not been good. It seems card comes with inadequate cooling, or else my unit is defective.

Fan noise has been normal, however during any demanding game it appears to overheat and freeze the entire system. Have to hold the power button to shut the machine down. It doesn't seem to be a software issue. I've experienced identical symptoms while gaming in OS X Leopard It's not always easy to reproduce - I do man raiding in World of Warcraft for hours with no problem, but if I'm playing solo in one of the more graphically demanding zones, like Netherstorm in Outland, it will crash after half an hour or more.

In Windows, I played Bioshock for about 20 minutes before it crashed. It definitely seems like it must be overheating. I've searched and not found many reports of others with the same problem. I only found 1 post on Apple's discussion forums. I have 3 hard drives and 6 sticks of RAM in my Mac Pro, so it gets fairly warm, and I wonder if the card's cooling just can't handle all of it.

I'm currently undecided if I want to contact ATI Support an experience I would love to avoid or void my warranty by installing an Accelero S1 rev2 cooler, possibly with the Turbo fan module. My system would start up and act normally for 45 minutes to an hour. Then, a wave of multicolored artifact blocks would sweep across the screen, and the computer would freeze, requiring a hard reboot.

Then, I had dark vertical lines from grey screen to desktop, and soon after reaching the desktop, it would freeze again.

Allowing the card to cool down would enable my system to start up and act normal for a short period, and the process would repeat. I hope the replacement board corrects the problem, but my confidence in the card is badly shaken. Thanks, Rich C. I just took out the stock card and the difference is outstanding. No problems, seems very quiet, goes like stink! Best wishes, Rob D. It worked like a champ for a day mows the GT and GT down in Pro Apps , but upon waking it the next morning the video was askew and redraws would leave black spaces or vertical bars.

Thinking it was just a random OS or driver issue, I rebooted. The grey boot screen also had vertical, blocky bars and it never got to the login screen that I could see. The screen went blue and did not change any further.

Just solid blue or blue with orange-ish blocks, I left it a few minutes to be sure. Booting into safe mode got me the login box, but the video was still screwy. Tried booting from CD, no difference eliminating the driver as culprit - although, as I said, the grey boot screen was also screwy.

Put the original card back in and it worked fine. Tried the once more to make sure it wasn't a seating problem and used the other power connector this time Pics here: This is the card I've been waiting for and putting the old card back in was heart breaking.

Installed it in my 1st gen MacPro model removed that XT that I sent pix of way back, with the Accelero X2 cooler swap and it didn't work. But on ONE display.
