Imac, NVIDIA GeForce 8800 GS

Hello,
I am planning to buy iMac 3.06 model.
I read somewhere that core animation is slower on "NVIDIA GeForce 8800 GS" then "ATI Radeon HD 2600 PRO".
The guy on that forum was saying that NVIDIA graphics card is faster in 3D rendering But slower on core animation. He was also saying that iMovie will be slower on NVIDIA graphics card then ATI.
Is that true.?
Sorry, I couldn't find the link of that forum, I read that only once.
Thanks
Dhaval.

Here are two interesting links:

Also, note that you can order a Built-To-Order iMac with the 3.06 Ghz processor and the Radeon 2600 card on the Apple online store:

IMac Nvidia GeForce 8800 GS Drivers

I am running XP Professional via Boot Camp. I run XP so I can play America's Army since it is a Windows only based game. The problem I am having is when I expand Americas Army full screen it completely locks up my iMac and I have to hold down the power button to reset it.
I have been told by several people that the problem is from the Nvidia GeForce 8800 GS drivers. I tried to up date the graphics drivers from Apple's and Nvidia's website with the latest driver. When I try to install the graphics driver from the setup file, it gives me the following error.
"The NVIDIA Setup program could not locate any drivers that are compatible with your current hardware. Setup will now exit."
Here is the location where I downloaded the driver from.

Here is a link to America's Army on the support forums.

Any help is appreciated.

Hey guys,
I encountered problems renaming the nv4 disp file that allen sent me (drivers still would not install)...so instead of replacing the original nv4 disp.inf file in windows, I opened the nv4 disp file allen sent me, copied the text, and pasted it in the original nv4 disp file in the NVIDIA folder after deleting the text of the original file and saved it...after that, the new drivers installed without a hitch...have yet to test whether or not the infinite loop is gone or not in Age of Empires 3 though...will keep u updated...thx for the file allen!

NVIDIA GeForce 8800 GS in iMac White

Hello, is posible "NVIDIA GeForce 8800 GS" in my iMac 2.16 GHz Core 2 Duo 24" (MA456LL)? I dont have guarantee.

No it will not work, your machine does not have the correct architecture so it will not fit.

Yet another problematic iMac 24" - 3.06Ghz - Nvidia GeForce 8800 GS

My iMac 24" (Early 2008) - 3.06Ghz - Model A1225 with the Nvidia GeForce 8800 GS card does not work properly.
I purchased my machine in September of 2008 and the issues began about four years later, in late sprin of 2012.
When the screen/display/video problems started, I got blue or pink screen startup failures, beachballing, crazy static lines through the screen, sometimes beeps or screen flickers. All of this started four years after buying it—and it is NOT unreasonable to expect a $3200 machine to last far more than four years.
When my machine stopped working I spent hours over doing diagnostics, reseating the RAM, a reinstall of the OS, all to no avail.
Digging for information on the Internet pointed to so very many other owners of this machine type having the same problem! But the cost to repair the card, as reported time time again, was close to $900. Angry and bitter, I boxed up my machine and started saving—and went back to using my 20” white G5 iMac (no problems with this machine, thank heavens!).
Is there any recall movement in effect? I don’t want to have to pay 900 or so dollars to repair a video card that is inherently defective!
Nvidia recently admitted to having produced lots of faulty Geforce cards for their laptops but also stated that there could be other products with similar faults (http://www.sec.gov/Archives/edgar/data/1045810/000119312508145974/d8k.htm). They have set aside about $150 million to redress the matter.
There is a UK forum dedicated to helping laptop owners with problematic Nvidia cards get help and they have started fielding quesitons from iMac owners, as well (
http://www.nvidiadefect.com/apple-imac-24-early-2008-imac8-1-defect-geforce-8800 -gs-t3813.html).
Is anyone else an unhappy owner of an early iMac 24" (Early 2008) - 3.06Ghz - Model A1225 with the Nvidia Geforce 8800 GS?

After a lengthy long-distance call to Apple Tech Support, both agents I spoke to told me that this is the first time they have heard about this issue. There are no repair protocols in place for this make and model of iMac with these issues.
I asked the senior of the two again, just to clarify, if this was the first time he heard about such a problem and he said yes. I then asked him if he knew the subject was being discussed here on the Apple Support Communities forum and he said that this forum is for users and is not used by them. I asked him if he thought it would make sense for Apple Techs to be up to date about common repair issues being discussed on Apple's own forums, and he said that he can't speak for Apple. I then asked him his opinion about the matter and he said, "I suppose so."
The "suppose so" line told that that I would get nowhere with him. I just hope the authorized repair center I visit is more up to date about this problematic iMac build that Apple's own Tech Support staff are.
Shame on you, Apple!

NVIDIA GeForce 8800 GS upgrade for 24" aluminum iMac -- can it be done?

I have a one-release-previous 24" aluminum iMac (bought about 2 months before the newest one was released). I play a lot of World of Warcraft, and would love to upgrade the video card to the new NVIDIA GeForce 8800 GS that works in the current 24" iMac.
Is there a way to do this at all? Apple solution, third-party solution, anything? I've heard rumors, but can't find out anything for sure.
All help appreciated.

Yes, I think it's technically possible, but you'd have to purchase the stock part from an Apple specialist (a corporate store probably wont do it) and have them install it. Expect to pay $300+ for the part alone. Even then, there's no real guarantee that it will work, even though they do indeed use the same form factor. There may be power/thermal issues.

IMAC's NVIDIA GeForce 8800 GS w/512MB up-to-date?

I am currently using a 20" IMAC and have been thinking about purchasing a new one.
I was curious to know "*NVIDIA GeForce 8800 GS w/512MB GDDR3*" is a decent "UP-TO-DATE" card?
When looking at a list of NVidia's current cards available at http://www.nvidia.com/object/graphicscards_buynow.html - they list cards that have "*Maximum Memory Bandwidth*" of 103 up to 147 GB/s. with up to 1GB memory size!
This sounds allot better than the 57GB/s Max Memory that the IMAC card offers, which isn't even half of some the current cards.
Should I be waiting for the IMAC to get updated with better video cards? or is this the best card I am going to see for a while with IMACs?
Thank you in advance for any help given.

True, and those cards also cost $4-500. Nvidia has other cards with a similar memory bandwidth that they rate for extreme gaming. The GPU in the iMac is an on-the-board GPU which can provide reasonable performance at a reasonable price. It ranks about mid-way in Nvidia's 8-series of video cards. If you want something faster, then you need to move up to a Mac Pro. For the vast majority of iMac buyers the video performance is more than adequate. But if your software needs demand higher performance, then the iMac is not for you.

Is the NVIDIA GeForce 8800 GS worth the money for Final Cut Express?

Hi,
I'm considering a new iMac 24, but not sure if the speedier on is worth the money.
Currently I use a MacBook Pro 2.2 for Final Cut Express with a 23" cinema (mostly DV, some HD) and that works okay, but won't play back in real time when I composit video.
Anybody know if the NVIDIA GeForce 8800 GS will help in that area?
Thanks,
KC

The speedier video card is great for 3D stuff, but it won't matter a wink for Final Cut Express, which barely makes use of the video card.
Keep in mind that Final Cut is using the CPU, not video card, to perform the editing, decoding, and encoding of the video. The only time the video card comes into play is during playback of the video, and any of the video options available for iMacs will handle that just fine.
When you composite video, the hard-disk throughput will start to come into play. The dinky 5400 RPM disk in your laptop will adversely affect the performance of that.

NVIDIA GeForce 8800 GS issue

I have a 24 inch iMac with a NVIDIA GeForce 8800 GS video card. The computer is out of warranty.
A while back I noticed that, while playing World of Warcraft, the computer would have a sort of graphical glitch and then freeze up.
This happened a few times, infrequently, until finally the computer would not start at all.
At the startup screen with the apple logo, the wheel would spin a minute, then pixels would appear all over the screen and it would freeze. The screen would then turn to a bright orange color and stay that way.
I took it in to the mac store, where I was told the video card had failed.
They replaced the video card, which I had to pay for, due to the computer being out of warranty.
I have had the new video card now for about two weeks. I just loaded World of Warcraft for the second time on it. After playing for less than 20 minutes, the screen glitched out (pixelated flashes) and then froze.
I am now afraid to play the game.
I have never had the computer freeze while doing anything else.
Considering I just spent $600 to replace the last video card, is there anything I can do to figure out what exactly is causing this problem?
Thanks.

Hi Riley71
I'm not sure what you were charged $600 for, but I would take it back and either ask for my $600 back or that it be fixed correctly.

My Mac Pro (2006) with NVidia GeForce 8800 GT is not detecting a second display. What can I do?

My Mac Pro w/ NVIDIA GeForce 8800 GT does not detect a second display from the System Preferences / Displays. Even though I select the "Detect Displays" button, nothing happens. I also have Bootcamp and Windows 7 in a partition on my drive. When I operate with Windows 7, there is no problem detecting both of my displays. However, when I operate with Windows 7, there is no sound signal sent from my sound card. When I switch back to the OS X then I get a sound feed from the sound card, but then it will not detect more than one monitor. I'm ready to pull out my hair. Anyone have suggestions?

Photoshop CS4 Issues with the NVIDIA GeForce 8800?

I have an Mac Pro Intel 2 x 2.8 GHz Quad-Core Xeon with 6GB RAM running OS X 10.5.5 and an NVIDIA GeForce 8800 GT driving two monitors.
I just installed Adobe Photoshop CS4 fresh from a factory CD.
When I perform a Distort -> Lens Correction or do a Free Transform to rotate an image an arbitrary amount, and then follow that with a resize (tried 133% and 166%), the image ends up with a pattern of gray plaid overlaid -- especially visible in the darkest shadows. The pattern appears only on the rotated layers of an image.
This pattern persists if I quit and restart Photoshop, BUT -- there's no pattern visible if I open the same image in Photoshop CS3. It only appears in CS4.
This is easy to reproduce -- I just tried it with an image I created in Photoshop at 5x7" at 240dpi and filled with solid black.
I dropped a Bug Report to Adobe, and they wrote back suggesting "This is most likely an issue with your video card driver."
Anybody else out there having this issue? Anyone with an identical setup want to test this?

I'm seeing what you are talking about when viewing at 200% and up on my 300dpi images. I'm thinking that its the new pixel grid overlay for dialing in the details on the image.
No, that's not it. I can see it at 100%, and only on images that have been rotated and resized.
In fact, yesterday I rotated one layer under an unrotated layer, and only the rotated layer showed the plaid pattern.
And it's not a simple grid -- it's a real plaid-like gray, almost like stretch marks.

IMovie08 has never worked for me, is it My NVIDIA GeForce 8800 GT card???

My preinstalled copy of iMovie v 7.1.1 will not startup, the dock icon will show that the app is not responding
I have a fresh out of the box 2 x 3.2 Ghz Quad-Core Intel Xeon Power Mac
pre-installed Mac OSX 10.5.1
I migrated from my titanium laptop to my new Mac.
migrated my user account, applications and system settings
then used the Mac OSX 10.5.2 combo update
I then reinstalled iMovie
running disk permission repair before and after each of the step I took above
still no go
Application Not Responding
several post state that removing some of the preferences will help this issue but so far those haven't worked at all in my case
would be great to know exactly which preferences have anything to do with iMovie
I have scanned over the discussions and seen this very topic all over, but no apple tech responding.
please let us in on how to resolve this issue
I hope we can do this without completely reinstalling all software.(makes a preinstall pretty useless)
thanks for any and all suggestions

Applemecanix are the Microsoft of card flashers.
There are at least 5 other flashers on Ebay who will sell you the EXACT same card, with the EXACT same ROM flashed on it for around $100 less.
For that matter, a little time on MacRumours and you could figure out how to make one yourself for $200 less.
However, if you have money to burn, by all means give it to them.

Is the ATI Radeon HD 4870 quiter than the NVidia GeForce 8800 GT ?

My NVidia GeForce 8800 GT just died and I have the choice to have the same one installed or to to go for the ATI 4870. (Technically I prefer the ATI but my family would prefer the quieter one!)
My main concern is the noise. Is the 4870 quieter or noisier?

I haven't run Photoshop for hours on end or otherwise made such intensive use of my card but I don't hear the 4870 run at all, As the Hatter says there is a noise at startup but no more. I have never used the other card you mention to compare it.

NVidia GeForce 8800 GT *and* GeForce GTX 285 in a Mac Pro?

Hi,
my Mac Pro came with an nVidia GeForce 8800 GT, and I've now bought an extra GeForce GTX 285 Mac Edition (for the Compute Level 1.3 double precision floating point capability in CUDA).
(Everything bought from the Mac Store)
I wasn't aware that I was expected to throw away the GeForce 8800 GT , what with the other three PCI-e slots being free.
The GTX 285 (max requirement: 204 W) requires two extra PCI-e power connectors. The 8800 GT (max: 110 W) uses one. There are only two available from the motherboard though.
So, *although I realize this isn't supported*, has anyone else managed to scrounge some current from somewhere else on the motherboard?
I'm only using one hard drive and one optical drive and no other PCI-e cards. Surely the power supply (around 1000 W ?) can supply the extra?
Does anyone know how much current the PCI-e extra power connectors are rated for?
Thanks,
colin

Search long enough and you may find...
According to this
http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress
The PCI-e slot can supply up to 75 W, whilst a 6 pin cable can provide another 75 W.
So:
2 PCI-e slots + 2 auxiliary 6-pin connector = 300 W
"Even with only two 12 volt lines the standard implementation of PCI Express power cables use large enough gauge wire and a good enough connector to provide much more than the three amps per wire required to provide 75 watts. Nonetheless, the 6 pin PCI Express power cable officially provides only 75 watts. *In all likelihood, however, real implementations of this power cable can provide far more than 75 watts.* "
Hmmm

NVIDIA GeForce 8800 GT and 10.5.7

The OpenGL problems with the NVIDIA GeForce 8800 GT video appear to be fixed in 10.5.7.
No screen artifacts, no screen redraw issue so far.

Very nice. My 3d objects no longer turn white while painting on them or manipulating them, though painting into the surface appears to be considerably slower than it used to be.
edit: I have an m8600GT, but had OpenGL issues which are resolved nonetheless.
