X1900 XT

the word must be getting out. the Apple Store notes that ordering a Mac Pro with an X1900 XT will "delay shipment of your Mac Pro." doesn't say for how long.

It does not.

X1900 G5 Edition lock-ups

FYI.
Just had the second lock-up in just under 2 weeks of the Quad coming out of Sleep mode.
Only recourse is power off as the graphics driver corrupts the whole machine. Ugh.
I've reported it to ATI, but who knows when we'll get a fix. Bottom line, save any work (Aperture isn't an issue but CS2, FCP etc. are).
If any others have a similar effect, please provide feedback to ATI (not that the card was on their feedback list a few days ago, so I put it in the comments area and selected "Radeon")
When system comes out of sleep mode, the screen is somewhat dithered and diagonal arrays of 1/8" blocks (around 1/4" apart) flash intermittently. Cursor is a translucent rectangle around 1/2" x 3/4" with the mouse pointer barely visible at top left. Although the mouse can be moved, nothing appears selectable. Option-Apple-Esc does not appear to bring up the force quit dialog (there again, nothing is very readable).

Hi,
I have X1900 G5 from one month. I am satisfied although I had some problems during instalation.
But what did you expect? In fact this card isn't faster then NVIDIA 7800 GT.
Look here:
http://barefeats.com/quad15.html
I knew about it before I bought it.
But, first of all, it is very difficult to find and buy an 7800 GT card, and secondly, the ATI card costs 349 USD and NVIDIA about 780 USD (at: http://www.welovemacs.com/6613835.html )
So, which card is better?
Thats my thoughts.

EFI Update Fixes XP Performance ... Even with X1900

Before installing Windows XP in my Mac Pro via Boot Camp, I just wanted to make certain that the recent EFI firmware update fixes all the issues, including for Mac Pros with the X1900 video card.
Thanks,
Clark

Making it easier, and better support, and eliminating known issues; but, ALL the issues is a tall order.
Also, it is probably a lot easier to skip the BootCamp partition and just throw another small drive in.
Searching for "X1900 + Boot Camp" by date yields:

Using a VGA monitor with Mac Pro: DVI to VGA adaptor cord & X1900 card

I will be purchasing the MacPro with the ATI Radeon X1900 XT. However, I want to continue using my dual Viewsonic CRT screens till the end of the year until I make the leap to a new LCD display. I know Apple sells a DVI to VGA connector and in fact I believe it to be included as an accessory.
Here is my question:
The graphics card I am buying (the X1900) is designated as a DUAL LINK DVI. The Apple DVI to VGA adaptor cord has a DVI -I SINGLE LINK male connector. Will this DVI-I single link connector properly mate to the female dual link connector on the X1900 graphics card? If it will, I'm probably in business. If it won't, does anyone have an idea for a workaround?
Many thanks, John

The DVI to VGA adapter works fine with the Radeon X1900XT (and the Geforce 7300GT and the Quadro FX4500).
The DVI to Video adaptor works on the Radeon, but not on the two Nvidia cards.

Will X1900 support a DVI to comp cable

I have a spare HD tv, and I would like to hook up my mac pro to the HDTV. I looked on line, and I saw a DVI to Comp cable.
http://sewelldirect.com/DVI-to-Component-Adapter-Cable-10ft.asp
I looked at the X-1900 from ATI and I thought it could support the card. has anyone tryed doing this before? or is there another way to hook up my HD to my mac? I do not have a HDMI connection on my HD, only component.
Thanks

DVI to HDMI - as to the X1900, it 'should' (I know the 8800GT works).

VIDEO CARDS QuadroFX4500 and RADEON X1900 won't work

I have the TWO VIDEO CARDS AND CAN'T RUN VIDEO WITHOUT IT GETTING STUTTERING VIDEO. LOOKS LIKE NOT ENOUGH MEMORY. WITH JUST THE 4500 ATTACHED TO 2 30 INCH APPLE MONITORS I WOULD GET A HORIZONTAL LINE ABOUT 1/3 FROM THE TOP OF THE SCREEN. SWITCH DVI'S AND IT APPEARS ON THE OTHER MONOTOR, SO ITS NOT THE MONITORS. USED THE HARDWARE DISC AND THE LINE SHOWS UP WHEN YOU START. HAVE HAD THE $500 REPLACED TWICE BECAUSE APPLE SAYS THATS THE PROBLEM BUT THE LINE STAYS. NEVER MIND I CAN'T CONNECT THE OTHER 2 30 INCH APPLE MONITORS WITHOUT EVERYTHING SLOWING DOWN. I HAVE ONLY APPLE SOFTWARE ONE THE 07 MACPRO WITH 6GIGS OF DRAM AND TWO HARD DRIVES 500 GIGS AND 750 GIGS and one 750 external Seagate hard drive.

Sorry, didn't realize till later,I wasn't looking. No they never worked together. Actually I first had a nVidia GeForce 7300 GT from apple to go with the 4500, but it still sits in a box, was completely incompatible or pooched???. The Quadro 4500 always gave me a horizontal line when only two 30 inch Apple monitors were hooked up.Its been replaced a couple of times, still the horizontal line remains. Recently I acquired the X1900 thinking the dual dvi output could run one more 30 incher and one single link out to my 55 inch plasma(a dream I once had). I can get slideshows from Aperture to run, but no full screen video. It slugs along skipping every few frames. My 2 year nightmare continues. Thanks for your inquiry though maybe you know what is or should I say isn't happening. This is my second computer since my Commodore Vic-20. The first one was a G5 fully loaded that blew up 3 weeks after its arrival and finally was returned for my current Macpro. Thank you Applecare! I'm a very frustrated Newbie.

Mac Pro + X1900 XT crashing after boot (Leopard) - please read...

I have a Mac Pro quad 3GHz w/ ATI X1900 XT videocard. It's one of the first models released.
For the past 4-5 months I've noticed a few pixels on in random places - looks like stuck pixels on an LCD, but they're not as they move around from time to time and sometimes aren't there at all. It progressed to horizontal lines across the screen in places - following window boundaries, etc.
A few weeks ago I de-dusted the X1900 (there was much), applied latest Mac Pro firmware update and applied that recent X1900 XT firmware update. All in the same hour. The dots went nearly totally away, but the lines did not.
In the past 4-5 days, my Mac Pro basically freezes up within five minutes of boot. Can be running different apps. UT2K4 or just activating Expose or doing nothing. Right now it's still up amazingly after 30 mins.
I've got some screenshots and I found some crash log entries that correspond. Please have a look:
http://www.blakespot.com/macproleopardcrash/
I also took a 10 min HD video of the crashing I will put on a DVD and take to the Genius Bar to show the problem, if I need to send in hardware to Apple for repair.
I would love to think it's the X1900 and it overheated or something and became damaged so that would be all I need to send in. Note that NONE of these problems were at all present in the first 6 months of life or so. And yes, the crashing is post-Leopard install.
Very troubling. Is anyone else having issues like this? Any input appreciated.
Thanks much.

I have had nothing but trouble with ATI cards on all of my macs, I really wish Apple would drop the ATI card altogether and replace it with an nvidia 8800gtx,
its the only thing still stopping me from buying a mac pro,
the nvidia cards are either 256mb £99 or £1,000 quadro (old technology and overpriced), they need a card in the middle ground that's not an ATI

Crash with ATI Radeon X1900 XT and second HD display (DVI) ?

hi ! i have a realy tough one for you guys : since 3-4 days i've been getting this realy strange (and scary!) kernal panic screen / crashes / freeze with my macpro dual 2.66 with ati radeon X1900 xt.
the crashes keep coming while doing extensive work (video converting, renders) or just letting the macpro running doing nothing much all night long...
now this is what i found for now : if i disconect my 2nd display (samsung syncmaster 2493hm HD in DVI 1080p) it seem to be stable. when i reconnect it sometime it can run again with this 2nd display for a while but when i leave a render all night long the next morning it will be frozen, nothing on screen (all black).
after rebooting it get this crash report from the system :

Are you really still running 10.6.3? you will need 10.6.5+ so do that and make a clone.
ATI 5770 from Apple Store - like 1000s of others have done and in the comments section on the store page.

What is a good replacement for the ATI Radeon X1900 XT on a late 2007 Mac Pro

I recently took my late 2007 Mac Pro to the Apple Store because it was running quite loud. They diagnosed the problem as the fan on the ATI Radeon x1900 XT video card. Whie the card works fine otherwise, I was thinking of replacing it. I noticed some online recommendations that I need to upgrade to perhaps the Radeo HD 4870 if I want to install FCP X on this machine. I do use the Mac Pro for video editing, but haven't switched yet to FCP X. Anyone have a suggestion on a replcement video card that will work both on this machine and will be compatible with FCP X.
Thanks for any advice.

Thank You

I don't use Bootcamp/Parallels/Windows but I saw in the Bootcamp forums that someone solved this issue by going to the ATI site and downloading and installing the X1900 drivers for Windows (http://ati.amd.com/support/driver.html). They had to do this while in Windows (which was difficult) do to the garbled screen but managed to suceed. Not sure why they didn't download the trial version of Parallels and do the same thing with an ungarbled screen.

Mac Pro, ATI X1900, Apple Cinema, and Boot Camp

Ok so I finally got Windows to install on to my Mac Pro. This is a long explanation because it includes a lot of information for users who may be having the same problems I had. My problem is at the bottom, but for those of you who are still stuck on the blank screen, READ ON!
Many have users been having problems installing Windows on Mac Pros with the ATI x1900 video card.
For Example, after running boot camp and loading XP the screen would go blank.
To get around this use the DVI to VGA addapter and plug a seperate monitor in, once the computer has finshed installing Windows, then install the drivers.
At this point my graphics card was still not installed correctly. I downloaded the driver off of the ATI website, however I kept recieving errors. So I unpakaged the driver and had the computer find a driver in that folder. Once this was done I went back and installed the remaining software without errors!
Now, currently I am still having to use a second monitor because my HD 23 inch was just showing a blank screen. To fix this I,
1. Installed the video card controller from the ATI website for the ATI X1900
2. Opened advanced settings and supported HD 1080i
3. Connected my HD monitor in the second DVI slot
4.exteneded onto that monitor
5. Switched that monitor to primary
And Perfect! It works
However, this is where problems began to arise. After customizing everything to my taste, I ran a test within this same program which sets all of your graphics card's settings to the optimal setting. I walked away because it was taking a long time, and when i came back my screen was totally messed up. It looked as if the settings had been changed and it had been moved up. With the top of the windows screen down where the dock is supposed to be, and then the dock right above that. I cannot correct this and it is extremely frustrating!
Is there anyway for me to correct this? It is normal in Mac Mode, but in XP i can't correct it. It just seems like there is one problem after another!

so did you install the bootcamp drivers?
because i had no luck with ati's drivers from their web site but apples drivers worked fine.

Note regarding ATI X1900 XT with Mac Pro, Leopard

To all who are experiencing any of the frequently reported problems with the hardware/software combination listed in the subject heading:
I purchased the ATI X1900 XT as an upgrade fro my Mac Pro in January. I never experienced any issues with the card in OS X Tiger, but several months ago I began to experience overheating issues in Windows XP (Boot Camp) when playing graphics-intensive games. The overheating caused visible graphics corruption/artifacts, graphics system resets and even spontaneous system restarts. The frequency and severity of these symptoms actually increased over time, leading me to believe that the card was either defective or that the overheating was causing degenerative/cumulative damage to the graphics hardware.
I recently upgraded to OS X Leopard, and all **** broke loose. Immediately after upgrading, I began to experience frequent graphics corruption/artifacts (in the form of spurious horizontal lines), system lockups/freezes and spontaneous system restarts. None of these issues were present in Tiger. The system became completely unreliable and essentially unusable.
It was initially a popular belief that Leopard's graphics drivers were somehow buggy or incompatible with the X1900 XT. After my experiences, I don’t believe that’s the case. I think that the issues reported are symptomatic of hardware, not software problems. Leopard is merely a catalyst. Leopard's increased leverage of OpenGL stresses the graphics hardware in ways that Tiger did not, causing an overall increase in graphics hardware temperature. I believe that the glitches/artifacts/system freezes/restarts that I experienced were not due to buggy drivers, but due to the graphics card overheating as a result of the increased load placed on it by Leopard.
I brought my X1900 XT in to my local Apple store today and asked for a replacement. Fortunately, they had one in stock, and they gave me a new card on the spot. The technician was apparently well aware of the issues, and mentioned that they have had a lot of similar problems with new iMacs.
Since installing the new card, I have experienced no graphics corruption, system freezes or spontaneous system restarts, either in OS X Leopard or in Windows XP gaming.
I would urge anyone who is experiencing problems with the X1900 XT (in either Windows or OS X) to have their card replaced by Apple - assuming that their card or system is still under warranty, that is.
I suspect one of two possible scenarios is true:
Theory #1: The Rev 1 X1900 XT is inherently flawed and has problems with overheating, which is exacerbated in OS X by upgrading to Leopard. Due to Leopard's greater leveraging of OpenGL, there is increased thermal stress placed on the card relative to Tiger. The overheating is evident in Leopard as graphics corruption/artifacts, system lockups/freezes and spontaneous restarts. The Rev 2 X1900 XT has (theoretically) corrected the problems inherent in Rev 1.
Theory #2. The thermal management system of the X1900 XT (all revisions) is inherently flawed. The card will slowly cook itself over time, and the effects are degenerative and cumulative. As the age of the card increases, so will the occurrence of graphics corruption, system freezes and spontaneous system restarts, especially when playing graphics-intensive games or running OS X Leopard.
I sincerely hope that Theory #1 is the case. I’ll be watching my system closely as I continue to use the new card, and hopefully there will be no further problems with overheating.
If theory #2 turns out to be true, then Apple has a huge PR nightmare on its hands, as each X1900 XT for the Mac is essentially a ticking time bomb that will self-destruct within months of purchase.
The funny thing is, this isn’t the first time I’ve had graphics card trouble with one of Apple’s “professional” towers. I bought a G5 several years ago when they were first released. I had problems with the stock nVidia graphics card in the form of what came to be known as the dreaded “black screen of death.” This became a commonly reported issue, experienced by many owners of the G5 in its first revision. Apple replaced my card and the problem never reoccurred. I’m hoping that I’ll be as lucky this time around.
I think it’s apparent that Apple’s batting average with graphics cards isn’t exactly stellar. It’s curious, considering that Apple offers a very limited selection of graphics options for their towers. One would think that by Apple only offering 3 graphics options, they would be able to have fairly tight control over the quality of the hardware, and plenty of time and resources to devote to testing. Unfortunately, I’ve had more graphics hardware-related problems on my Macs than any PCs I’ve ever used. That’s embarrassing, and Apple needs to do much better than this.

I replaced my G5 Quad with a Mac Pro 8-core. The Mac Pro's thermal design is far superior to the G5's. The G5 Quad's liquid cooling system has a much bigger task (IBM doesn't publish the thermal dissipation numbers on their PPCs but I suspect they are high) than the more efficient Intel Xeons. The G5 liquid cooling units are troublesome and the issue is something I think Apple is quietly solving by replacing failed liquid cooled G5's (that are still under warranty) with Mac Pros (a very smart PR move). My primary concern when I switched to a Mac Pro was issues with the X1900 XT graphics card failure rates posted on the web and in these discussions. The very latest generation of the X1900 XT (July 2007) are reported to be more reliable. Many G5 owners are still reporting failed cards. Given the much higher thermal environment and the remarks in this thread, I can now see why. The interior of a G5, especially Quad, gets too hot for this ATi card. I had the nVidia GeForce 7800 GT in my Quad. That was a very good card. Still, the issues with the ATi x1900 XT may indeed be a thermal design issue that AMD may need to either address directly, or turn to a 3rd party solution.
I installed a 3rd party cooling alternative, Arctic Cooling's Accelero S1. It's a passive system that replaces that hairdryer fan with a large heat sink. The package includes upgraded heat sinks for the power regulator (much beefier than the stock), and for each memory chip. The heat sink is a large conductive cooling assembly that uses 4 heat pipes. The vendor claims that using this system increases the case temperature by 1°C, which is easily handled by the system cooling system. So far, their claim appears to be valid. Since there's no longer a fan, you can imagine how quiet the system has become. The only installation hitch is that the black support clips were made for the PC version and the Mac Version adds a beefy support rail on the spine of the card. The workaround is to trim off the lower tang of the clips so they just rest against the support rail.
After reading this, I'm tempted to add the "Turbo" option, a couple of high volume low speed fans that fit on the radiator. I'm trying to "stress" the system by running SETI@Home 24/7 while doing all the other work to see how hot and how loud I can get this system. So far, no disappointments. This is the quietest workstation I've ever worked on. Even when "hot", the fans are not loud. The passive cooling system seems to work very well. I left Star Wars-Empire At War up and running in the menu for hours one day and it didn't seem to suffer from any ill effects. I have owned this system for just over a month. I will add more thermal load after I crank the system memory up to 24 or 32 GB. If there are any real cooling issues, I will find out about them next summer. I really dread the prospect of plunking down another $2k for the nVidia 4500 FX (I really don't need the 3D audio support) to get comparable video support.

GPU enhancement issues with ATI Radeon X1900 XT

Upon startup, PS CS4 turns off GPU enhancements and displays the following error message:
"Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements. Check the video card manufacturer's website for the latest software."
Problem is, according to all the research I've done, PS should be perfectly compatible with my Radeon X1900 XT card. To further complicate things, ATI does not appear to have driver updates for Radeon X1900 cards for Intel Macs on their website. Even a Google search doesn't seem to bring up any sites with the drivers. It's maddening!
Is anyone having similar problems, or can anyone offer advice? All Adobe and Apple support seem to recommend is updating my drivers, but of course that doesn't seem possible. Thanks!

I'm having a slightly different problem, but it fits in with what others are saying. I upgraded to CS4 the other day, and starting that night my system (a Mac Pro with the Radeon x1900 card) I have had issues with my display - that is, sometimes the display won't work after waking from sleep. The display is a 23" Cinema.
The rest of the system is fine (I have a laptop so I can peek in and control it remotely), and everything is just as I left it. The display itself responds to being turned on and off using the power button on the side (that is, the tiny light on the front turns on and off...). But the screen itself is pitch black, off entirely.
I took out the video card and it was, indeed, black on the intake with fine dust, so I cleaned that as best I could. That did not solve the problem, however.
Pull the plug to my desktop and plug it into my laptop, and it works just fine. Plug it back into the desktop...dead. The only thing that seems to fix it is shutting it down for a time. I don't know how long is required but it's more than a few minutes (so it's not a simple reset) and it's only been a few days and so far I've just gotten frustrated and left it over night - so it certainly could be related to cooling down.
Seems like Adobe is the culprit as the problem has *never* happened before, and has happened every day since the very day I installed CS4. I'd be reluctant to believe it...if I hadn't spent hours just upgrading to CS4 (I won't go into the legendary problems which plague Adobe's installers).
Given that when I bought this system a couple of years ago this was one of the few video cards I could choose, and it's the high-end of the bunch, there must be a lot of folks out there with this set-up plus CS4...
Sounds like the suggestion is to inhibit performance in CS4 so it doesn't fry my video card? I am running Temperature Monitor, but it doesn't show me that particular stat...

Nvidia GeForce 7300 GT and ATI Radeon X1900 XT

I have a Mac Pro 2,1 running 10.6.1 and BootCamp.
I had a Nvidia GeForce 7300 GT video card in it and it ran well under BootCamp.
I installed a ATI Radeon X1900 XT.
Under BootCamp the 2 cards seem incompatible, with an error message that the driver on the Nvidia card has been disables due to an incompatibility with the other card.
Is there a solution for this?
If I wanted 2 cards inside would they both need to be the ATI's or Nvidia's?
Thanks

Hi I would maybe get a Apple Upgrade Kit the GT 120 is 512MB's & dose not use all 16 lanes as it like to make you think & will work on 2006 Mac Pro's at $149.00 I would say if you just want more displays get two & eBay your old cards. Please know if you game you will want more power but if only for more displays this 1 slot card is great.

PC with ATI X1900 Graphics card - Can't drive my 23" Apple display

I recently assembled new PC with A8N-SLI mobo and ATI X1900 All-in-Wonder card (with DVI-I out) driving a new Apple Cinema 23" display. I've not been able to get the display to come up on boot except for a few occasions when I disconnect and reconnect the ADC cable to the power supply after boot. I'm guessing this problem has to do with mixing Apple and PC (OK, it was a gamble).
Any ideas on how to get this combination working?
Thanks.

OOPs all. I looked at the other posts and see my answer.
Thanks anyway.

No Signal on Mac Pro with Radeon X1900 and ViewSonic VA1912wb monitor

I have a Mac Pro (purchased in Summer 2007) with an ATI Radeon X1900 (512mb) graphics card. I am connecting the card to a ViewSonic VA1912wb (LCD) monitor.
When I first bought the system, it worked perfectly fine with the monitor. While it did not detect any display at certain times (when trying to install Windows XP for Boot Camp, and sometimes when starting up Boot Camp), I understand this had something to do with the video mode, and when I connected an old CRT monitor, everything worked fine.
Now, when I turn on my Mac Pro, the display sometimes does not show up at all. I often have to start and restart my Mac 5 or 10 times before the ViewSonic monitor will detect a signal and display. Sometimes even more (I was unable to get a display at all last night, after restarting over 20 times).
Does anyone know why this could be? It's very frustrating to have a nice computer and a nice monitor, but not be sure if I'll be able to start it up at all.

First you got to isolate the problem... is it the monitor, the graphic card, or the cable.
The easiest way to find it out, is to connect another display. Does it work, you know the monitor is to blame... if not, it's the graphic card or the cable.
Try another cable... if it still don't work, it's the graphic card.
I have the same graphic card and while surfing around the net, I figured out that these specific model has to be treated very carefully because it is overheating very fast. So it's strictly recommended to clean it every once in a while from dust... using compressed air.
Search around the net and you can find workarounds and pictures. Like this for example: http://www.macosg.com/group/viewtopic.php?t=13207
