Mac Pro :: 8800 Video Glitch?
Sep 17, 2008
I got my Mac Pro in March. So I've had it for a good 6 months. In that time, at least 3 times my 30" Cinema Display has shown some sort of video glitch. I'm convinced that it is the 8800, and not necessarily the Cinema Display.
What happens is, out of the blue, and for reasons I'm not sure of, I will get a strange pattern of brightly illuminated pixels on the display. They are "fixed". In other words, If I move and image around on the display, those pixels are stuck and do not move with the image. Also, if I take a screenshot, they do not show up on the screenshot at all. I had to try and take a picture with my camera to show you guys. A reboot and/or logout/login fixes it. I think it is some sort of bad video RAM or something. I've already upgraded to 10.5.5 and it did it again last night. I'm pretty sure it was the result of DVD player crashing. But then again, I don't know if DVD player crashed because of a video glitch. The DVD was kind of scratched up (netflix) and the computer did have problems reading it. DVD player beach balled when I tried to skip a chapter so I have to kill it. That's when I noticed the display was all screwed up.
3 times in 6 months isn't a huge deal, but it does make me worry about a pending hardware death of either my display or video card.
Anyway, have you guys seen this? Is it a cause for concern? Is my 8800 on the way out, or is it most likely some sort of driver or app hiccup that isn't really a big deal?
In these picture you can see the randomly scattered light green pixels. It's almost as if a color has been swapped out.

I purchased this card for my Mac Pro:
"NVIDIA GeForce 8800 GT (early 2008) Graphics Upgrade Kit for Mac Pro"
I spoke with multiple Geniuses. I spoke with AppleCare. Everyone is telling me that this is the card for my Mac Pro model. They looked up the model number and confirmed it. The original ATI card works in the machine.
I received the card, installed it, booted the machine, and had no video. Just two blank 20" displays. I tried using one display, reset power management, did a few other things while on the phone with a Genius. Nothing.
AppleCare sent me a new card (same model). Same issues. I'm looking at two blank displays right now. I'm as frustrated as I could possibly be. Are all the people I spoke to at Apple completely wrong and could this be the wrong card? Multiple people looked up the model number and they all point me to this card. It doesn't work, and since my ATI card works, I doubt it's the machine.

I have an Imac 24in that I purchased last June with the upgraded video card, NVIDIA GEFORCE 8800 GS W/512MB. Anyone know if it might be possible to upgrade it to one of the newer cards just released with the new imacs?

I don't know if this will work but would it be possible to use the EFI firmware from the GT8800 and flash it onto the GTX285 mac Edition? or something? to make it work on the Macpro 1,1 (2006-2007 Mac Pro Users)

So I was using my second monitor to run my G5 while transferring files to my new 3.2 octo, and then the past week I was using it to transfer my old PC files to my new PC. Now I finally just went to hook it up as my second monitor on my Mac Pro, and found out that I CAN'T FIT BOTH DVI CABLES TO THE PORTS!!!
They're too close together so I can fit one monitor into either port, but not both simultaneously. My monitors are the aluminum 23" ACD's w/ DVI.

My 8800 is quiet in idle, but during hours of WoW it gets extremely high. Anyone know any software that can adjust this?

I have an 8800 card that I bought for my Wintel box a couple years ago now. In the interim, I've gotten a Macbook and have totally fallen for OSX. As a result, as my Wintel box gets more and more crusty, I've been mulling over replacing it with a Mac Pro (or, preferably, the midrange mac minitower of myth, the i-Chupacabra). Assuming that I did get a Mac Pro, would I be able to cannibalize the 8800 that I have in my Wintel box and use it in the Pro, thus possibly avoiding the outrageous markup found in buying hardware upgrades from Apple? I am concerned that perhaps the 8800 GT offered as an upgrade is somehow physically different than the one that you can buy for the PC...

Acoording to this site the Top Spec old iMac's had GeForce 8800 The new ones have a GT 130. I am struggling to find any information on the GT 130's and i *think* the Nvidia site says the GT 130 have much lower specification than the 8800 GS. So how do they compare? Surely, the GT 130 is a lot better, right?

I have a 2008 iMac with the above Graphic card installed from new by Apple along with 4Gb Ram.
All was fine. Now it chimes on boot up but remains at a black screen, I have read that these Graphic cards fail.
They are listed on E Bay about £200 from Hong Kong, Is there a Current compatible card that can be fitted, that is cheaper?
Info:
iPod touch

There seem to be a few reports of problems running 750gb F1 Spinpoints with Nvidia chipsets. Does this apply to us with the 8800 or is it a Windows thing?
Anyone out there happily running a MacPro (08) with an 8800 and F1 spinpoints?

I try to use as much passive cooling in my PC's as possible. My current PC is nearly silent, however I am looking to replace my desktop with a mac pro. I would need the 8800 GT card, but am not looking forward to a lot of noise. Is it possible to mount a passive cooler on this model? Will it fit? I haven't really seen much mention of this anywhere.

I have an early 2008 Mac Pro with an EVGA 8800 GT installed. When I bought the computer the EVGA 8800 GT was almost silent even when under max load.
Now 15 months later the EVGA 8800 GT fan is making so much high pitch noise under load that I try not to use it for heavy 3d. The noises started after about 6 months after purchasing.
Monitoring the fan speed under Rivatuner shows that it goes to 100% performance under almost any load in order to keep it at a steady 80 degrees celcius.
I concluded that the fan was becomming less efficient over time and that it had to spin more and more in order to keep the temperature down.
Dust Cleaning
I try to clean the computer for dust every 4 month, blowing air backwards into the components of the computer to remove all the dust.
I normally use my mouth (trying not to spit) and a hairdryer. This seem to work okay for the most part, but not much for the EVGA 8800 GT.
After cleaning the fan is still quite audible and hovers at 85-90% under loading producing the annoying high pitch noise.
After only a few weeks its back at 100% under load. I tryed getting Apple to replace the video card, but they refuse to since it is still working. ( I hate this kind of deffinitions. )
- Would buying a can of compressed air and blowing it backwards into the EVGA 8800 GT remove more dust than the method I normally use?
- Would anyone recommend taking of the fan in order to clean it better or should the can clean enough? - trying to compare the risk of not being able to assemble the card again.
- Has anyone had any luck reducing the high pitch noise of the EVGA 8800 GT fan, and if so how?
Aftermarket Cooling
I did buy an aftermarket cooling system called Accelero S2 without the turbo module (fan) which recieves top reviews.
Despite having build some computers in the past I am a bit reluctant to install it by removing the fan completely because I am affraid that I will somehow break the video card in the process or accidently install it in a way that fries it when temperature rises under heavy load.
It sure is tempting to try the Accelero S2, but with the EVGA 8800 GT Mac going out of market I would have to dig deep in my pockets to get a replacement if something happends to the video card.
I think I also read somewhere that the instant you take of the EVGA 8800 GT fan you cannot put it back again. Which also makes me a bit nervous if the aftermarket cooler is not able to keep the card cool.
- Has anyone had luck installing the Accelero S2 without the turbo module (fan) and if so is it easy?
- Would anyone recommend installing the Accelero S2 without the turbo module? - I am not familiar with the success rate of aftermarket cooling and how skilled you need to be to be successfull.
- Has anyone had any problems not being able to keep the video card cool with the Accelero S2 and in that case was force to reinstall the default fan again?
I really wish I could reduce the noise of the fan so I can stand using it for 3d heavy stuff again.

Development of Apple's upcoming Mac OS X 10.5.5 Update appears to be winding down, with only a couple of new fixes making their way into recent builds, including one aimed at wireless issues.
This past week saw two new pre-release distributions of the 320MB Leopard update fall into developers' hands. The first arrived mid week as Mac OS X 10.5.5 build 9F25, but contained no noticeable changes from the build the preceded it.
More recently, developers were treated to build 9F29. That build tacked on a pair of fixes, one of which tackles an issue between Macs and previously joined AirPort networks, people familiar with the software say. The second fix was related to a graphics framework.
Seemingly at the tail end of its development cycle, Mac OS X 10.5.5 is reportedly hindered by a single known bug that prevents emails from being searched properly in Apple's Mail application.
The fifth maintenance and security update for Mac OS X 10.5 Leopard now stands to deliver 125 bug fixes when it's released later this month.[ View this article at AppleInsider.com ]

What the hell...ok, is anyone else having this problem? I ran Software Update (which installed iTunes 8.1 and the new FrontRow). After the installer finished, I opened iTunes and came across this:The bars labeled Name, Time, Artist, etc. are all messed up. They aren't clickable. It's like they're just stuck. And this is the same for playlists as well.So I tried restarting my Mac. Nothing, still there. I downloaded the iTunes 8.1 installer, installed, and it's still there.

I started playing World of Warcraft again after a 6 month pause. I have the same system (09 MP), but I discovered something new. From a fresh boot, everything works fine. I then launch WoW: it works perfectly fine.
After quitting WoW however, I get very obvious screen tearing all over my OS X apps. Windows tear when I move them side to wide in finder or any other app, and video has a similar tearing effect. I can't get rid of this problem without a restart... Can anyone show me how to "reset" my video without a complete restart?
[Edit-Solution: Enabling V-Sync *in-game* solves the problem *after* the game is closed.

From the reading I've done it's apparent that the NVidia 8800 card that ships as an option for the MacPro (jan '08) is slow for Pro App's.
I've read at some sites that this may be remedied by NVidia by rewriting / releasing updated drivers for this card.
What's the likely hood of this?
Or is there something in the architecture of the card that makes it maxed out?
I'm not annoyed at NVidia as I wanted a reliable card.
I just fried my 4th ATI (Retail) 9800 Pro 128 MB card in my Digital Audio PowerMac in the space of three years. I can't believe how many of these cards have been so unreliable. The first three were replaced under warranty.

I am trying to find similar comparisons. The refurb with 8800 is only 1599... which even to me looks like a great deal. Yet I am trying to find the two comparisons that work.
Searching is yielding lots of trash so I am probably too stupid to use that feature
I figure on popping in 4gb of RAM and being done with it, since I am only spending 1600 I look at it this way, if a real upgrade comes out in August I won't be out much if anything.

This is my first post here, hopefully i can begin posting a bit more and learn more about my mac pro. I just got a hold of an Apple Graphics Card Upgrade. The part# is MB560Z/A. It's an Nvidia GeForce 8800 GT, but it's the 2006 version with EFI32 firmware (or do i call it BIOS or ROM?) and won't work with the 2008 Mac Pro... and of course my dilemma is i want to use it in my 2008 Mac Pro. So is it possible for me to flash it (which i'm pretty sure it is) and more importantly is it easy to do and could someone tell me how (or point me in the direction of simple instructions) of how to go about doing it? Also, I understand there's always some risk doing these type of things, but would the chance of me screwing up the card be considered minimal? Is it easy to restore to the factory default if i want to place it back in a 2006 mac (i have no plans for that, but it'd be nice to know i have that option).

The next maintenance update to Mac OS X 10.5 Leopard will add support for the company's rebranded suite of internet services but also patch over a dozen other bugs that have withstood earlier updates to the operating system.
People familiar with the software say the Mac maker recently provided its vast developer community with a second pre-release build of the impending Mac OS X 10.5.4 Update labeled build 9E12.
Among the dozen or so code corrections baked into the latest build were fixes to a bug that would leave some Mac systems hanging on shutdown, and another that prevented applications from being assigned to Spaces via drag-and-drop from the application list.
As was the case with earlier updates to Leopard under testing, Apple has requested that developers evaluate the software broadly. Specifically, the company is alleged to have listed nearly two dozen core components that need special attention, including iLife compatibility, printing, networking, AirPort, and common applications such as Mail, iCal, and iChat.
Mac OS X 10.5.4 will also be required by Leopard users who wish to utilize the company's just-announced MobileMe service, a collection of online services and software announced at this week's Apple Worldwide Developers Conference as a more capable and advanced replacement for .Mac.
As such, the Leopard update, which currently weighs in around 150 megabytes, will be released within the next few weeks, ahead of the July 11 MobileMe launch date. [ View this article at AppleInsider.com ]

I'm seeing a severe graphics glitch. At first I attributed it to a VM, but it has started affecting my whole system. Repeated reboots will eventually clear the issue, but it will trigger again when I boot up a VM, watch a flash video, or do anything GPU intensive. This doesn't happen every time I perform these actions so I have had difficulty finding a specific cause.

Having some sort of a glitch on my Safari 5.0.2. It turns that if i only have a single window open, the tab will not hide but it will remain. On my macbook though it behaves normally, meaning wear there is only one page on safari, the tab will be hidden.Is there any way i could possibly make my safari behave normal again? Any nifty terminal commands?

When I go to play songs with the jelly visualizer on the visualizer will freeze for a few seconds after around 15 seconds, it is very annoying. I have an early 08 2.4GHz Macbook if anyone else with this model wants to see if theirs has the same problem incase it might be a hardware issue.

So for about a week or two now i have been experiencing this glitches that seem to come around after the computer has been on for more than 2 or 3 hours. I have noticed restarting the machine will get rid of them. I have a 2.4ghz MacBook with 2 gigs or ram from early 2008. I am running Snow Leopard 10.6.2
Does anyone know how to fix this? I think it might be a messed up graphics card, but i don't have much of a clue. I have noticed when trying to take a selected screen shot over the dock the glitches will go away, but they only happen on the dock, wallpaper, and window shadows, they are also random every time.

So far this has happened twice to me, once while playing CS:S, and once today while playing TF2. You can kinda see the weird shapes that appeared on my screen in my picture, except in game they covered the entire screen. Is this maybe the GPU overheating? (I added the red circles afterwards btw)
Could it be a problem with geektool?
edit: btw, it was fine after a restart

I have a late '08 MBP. A couple months ago I started having problems with my Mac running slow, and acting "glitchy." Since then I have maxed out my RAM and have over 60GB of free space on my hard-drive. I am still experiencing the same problems. What do I do? I think that I may have a virus, despite the common believe that Macs are not vulnerable to viruses.

Early this year I replaced the stock video card in my 2006 Mac Pro with an Apple supplied Nvidia 8800 GT card. I'm driving a 30" Apple Cinema Display with no problems but occasionally, when encoding video or playing full screen games, the card emits a high pitched tone akin to a smoke alarm tone but continuous. When discontinuing the encoding or stopping the game, the tone stops.

Has anybody upgraded their Mac Pro's stock graphics card to the NVIDIA card?
Does it make a big difference?
I'm playing way to much X3 Reunion at the moment, and I've noticed that the graphics on the PC screenshots look a lot better than what my Mac Pro produces. I don't know if it's a Cider thing, or simply down to the stock graphics card in the Mac Pro being a bit pants?
