NVIDIA 7300 / video support

Hi
The NVIDIA GeForce 7300 GT does not work with the Apple DVI-Video Adapter, is anyone aware of a way to get this card to recognise video displays like the 6600 can?
In theory this *should work* because one of the ports is dual link. Cant think why NVIDIA has dropped support, sure is bad for my system which relies on having 3 independantly addressable video outputs on one box.
Thanks for any ideas
Nick

Yes, the 7300 supports two monitors. One of the connections is dual-link (so will do 30" cinema) and one is single-link (so up to 23" cinema).
You don't need any adapter whatsoever -- there are two DVI connectors on the back. If you have a 30" and a 23" you need to find out which of the 2 connectors is dual-link... otherwise just plug in two smaller monitors.

Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia GeForce 7300 GT
I've been suffering with screen tearing, strange screen artifacts, etc. followed by totally unresponsive freezing machine. This problem has been happening to varying degrees for about 9 months.
Initially, I was able to mitigate the problem with smcFanControl. Adjusting the fan speeds up helped keep the machine cool and prevent most of the problems. Recently, we had a spell of hot weather and the fans just couldn't keep up. If you're using smcFanControl, the only fan speed that will really make a difference is the CPU. The HDD and ODD fans are no where near where you need to be.
Also, I noticed the machine was LOADED with dust when I took it apart, including the heat sink fins for the graphics card. If you have time you may want to try a thorough cleaning with compressed air before replacing the card. You just need to get through step 11 below to access what needs to be cleaned.
Based on reading here and elsewhere, I decided to replace the graphics card. To give back to the community, I wanted to layout the procedure here.
Where to buy the card.
I had a tough time finding the right card. I did exhaustive web searches using every combination of Nvidia 7300 GT, etc. You really need to search by the Apple part number. The Apple part number for the 7300 is 661-4179, for the 7600 is 661-4180. I found it at We Love Macs and at dv warehouse. I paid $248 for the 7600 card. BE CAREFUL buying a "refurbished" card. At We Love Macs, "refurbished" means "pulled from a working machine." Could be a machine with as much mileage as yours and prone to the same failures as yours.
The card is an MXM style card (generally used in laptops), with a giant heat sink and heat pipe assembly. The card can be separated from the heat assembly. If I had time, I would have tried a generic, cheaper, MXM style card.
Dispelling some myths.
People here and elsewhere have said that no Intel iMac graphics card can be replaced, that they're wedded to the logic board. The one on this model can be replaced, I've done it. Also, some have said you can't put a 256MB, 7600 GT in a machine that originally had a 128MB, 7300 GT. Also, not true. That's what I did to my machine and it is working fine.
So here's the step-by-step on my take apart and replacement. This is just one user helping out others, PROCEED AT YOUR OWN RISK. This takes about 1 1/2 hours to take apart and 2 to put back together.
1) Install the iStat widget and monitor the temperatures for a few days and record the temperatures (to be able to verify that you've completed the repair correctly later)
2) Make a complete backup of any internal drives and make sure the backup will be bootable (use Carbon Copy Cloner)
3) Use static safeguards, like an anti-static wrist strap.
4) Get a pen a stack of paper envelopes to separate and label the pieces you remove.
5) You'll need a #2 Phillips and #6, 8, 10 Torx. Most of the screws at T-8. There are 8 T-8s holding in the LCD. They are about 1 1/4" down. You'll need a long, skinny T-8 to get to them.
6) Unplug the machine and place it on it's back on a large white sheet of paper.
7) Remove RAM door, #2 Phillips x 2.
8) Remove RAM.
9) Remove 4 T-8s along bottom.
10) Remove large rectangular plastic bezel surrounding the whole machine, tilt up being careful not to stress iSight cables. You'll need to stretch it around the RAM ejection tabs.
11) Detach two iSight cables.
12) Peel up black stickers at lower corners of speakers.
13) Remove LCD screws, T-8 x 8. You'll probably drop a few, they're pretty easy to retrieve.
14) Remove two retaining screws on right hand LCD cable. T-6 x2 Unplug cable.
15) Remove LCD inverter cable, left.
Start unplugging everything connected to the logic board.
16) Unplug cable coming from right speaker. Note cable routing, it is the only one that's a little tricky. Also, note that the left one plugs in on the right and the right one plugs in on the left.
17) Remove right speaker. T-10 Note: left and right speaker screws are different lengths.
18) Unplug ODD blower cable.
19) Unplug ODD temp cable and lift up tape.
20) Unplug HDD blower cable.
21) Unplug the HDD temp cable.
22) Unplug the camera & mic cable.
23) Unscrew the clamp securing the airport card (has two antenna cables going to it, labeled PCIE), T-6 x 2
24) Unplug SATA cable.
25) Unplug Power cable, thick black plastic harness, socket.
26) Unplug ambient temp cable.
27) Unscrew the bluetooth card, T-6 x2.
28) Unplug CPU blower cable.
29) Unplug power button cable, 2 conductor, tiny cable, bottom left.
30) Unscrew left speaker, T-10, unplug from logic board, but just leave dangling, no need to remove cable completely.
31) Remove logic board screws. Be careful to segregate them, they have different lengths and different thread pitches and thread types. Some are machine threads going into metal, some are coarse threads going into plastic.
31a) Heat sink frame to case T-8 x 2
31b) Logic board to case T-8 x 3
31c) Screws at heat sink from arrows T-8 x 3
31d) Logic board at bottom near RAM slot T-8 x 2
32) Unplug ODD ribbon cable, be extremely careful. Release plastic tabs on each side to remove. Be sure it is fully and evenly seated when you put it back later.
33) Remove logic board with attached graphics card.
34) Unplug graphics card heat sink sensor cable at logic board end.
35) Remove graphics card screws 2 x T-6
36) Remove single screw from small L-bracket on heat sink 1 x T-6
Replace graphics card.
Reverse steps, put everything back together. Be careful not to pinch any cables when you put the logic board back in. When you put the LCD back in, if you can't get the screws to stick to the driver, use some glue stick from your kid's art supplies.
Test everything. You've disconnected every cable in the system.
I torture tested the machine with a space heater on it, 5 different videos of different formats playing at the same time. No problems.
I took a lot of pictures inside the machine. As soon as I figure out a good place to post them, I'll try to add a link here.
Good luck

Greetings!
I know this is in response to your post from over 2 years ago, but I was searching on Apple's site for the max RAM I can upgrade our refurbed iMac too and it brought up this post.
Oddly enough, I've been experiencing the same screen issues and locking up on our iMac as well. I was concerned it was a bad memory module, but now I'm thinking it's the same issue you found.
Because I bought this some 2+ years ago refurbed from Apple, I'm not surprised that could be the actual problem.
I've pulled this thing apart once to replace the hard-drive which crashed about a year ago, so I'm not totally new at opening it up, but this process you mention sounds pretty intense...just wanted to get your second take on it based on what I've done thus far.
Thanks again for posting this...it was an eye-opener as to what might actually be causing our issues with our trusted Mac!

NVidia 7300 GT

Hi,
I have a late 2007 model of Intel Mac Pro. It has a nVidia 7300 GT graphics card. I was wondering if i could add another one. Is there a Mac Specific 7300 GT ? or can i install the normal PC version of it?
Thanks In Advance.

You need a card made for the Mac Pro. (Are you really running OSX 10.4.1?)
Apple is no longer selling any NVIDIA cards that work with your Mac Pro, but their ATI card will work (despite Apple saying it's for only 2008 and 2009 Mac Pros) if you upgrade to OSX 10.5.7
<http://store.apple.com/us/product/MB999ZM/A?fnode=MTY1NDA5OQ&mco=NDE4NDMxOA>
The nVidia 7300 GT is available used

as is the NVIDIA 8800 GT. Be sure to get the one for the 2006-2007 Mac Pro. There is a different version for the later Mac Pros that won't work in yours. It also will require you update to OSX 10.5.7

Single NVIDIA 7300 GT...how would it handle dual 20' Dells?

I'm a student film editor...just wondering how well my single NVIDIA 7300 card in my MacPro would handle dual 20' Dell Widescreens. I have one, but I feel like I need a second one...but I don't think I want the second one if it means that I really ought to upgrade my graphics card as well. Any advice?
Mac Pro Mac OS X (10.4.8)

they will improve the speed of the graphics fitting 2 7300 GT's
This is a pile of bollocks. Adding a 2nd Nvidia 7300 GT will only give additional display support and will make no difference to your GPU processing abilities. SLI is not supported under Mac OS X.

Need info about nvidia graphics card supported with premiere pro cs5

Hi
I need information about nvidia graphics card supported with premiere pro cs5
If I have a computer(portable) with this video card or graphics card :
nVIDIA® GeForce™ GTX 285M with 1GB DDR3 Video Memory available in Single or Dual (SLi) Configurations
Microsoft® DirectX® 10 Compatible
is it going to support MPE in premiere pro cs5?
Regards,
Vinay

To be clear:
You asked about supported cards. Here is a list of supported cards. Others on this thread are telling you how to make an unsupported card function to some degree using a method that is not advocated by Adobe.

Using twoo NVIDIA 7300 cards: firmware bug? Screen refresh problem

strange bug with Mac Pro 2.66 Xeon:
I have two Displays, 20 and 23".
When both connected to the standard NVIDIA card in the Mac Pro, evreything is fine.
I ordered a second NVIDIA card wich I installed in slot 4, using 8 lanes for this card.
Now, when one display is connected to the standard card and the second display is connected to the second NVIDIA card, the screen of the display connected to the build in card (the 16 lanes card) does noet refresh correctly. You can not see what iMovie is displaying for example, iMovie screen is white and does not display what should be on screen.
Sometimes none of the main screen is refresehd (example: Safari content is not updated, while in fact it is!) but the mousecursor moves correctlyon screen.
Also third party software (like FotoMagico) is not updated on screen
Connecting both displays to one card and everything is fine!
A strange bug wich I guess is related to the Mac Pro firmware
I've tried the second NVIDIA card in all the PCI-E slots to see if this makes a difference, it does not.
I used the PCI-E configure tool to vhange the speed of the lanes for the PCI-E slots, also this makes no diffrence.
At this moment my second card is not usable.
This is a problem on all three Mac Pro's we tried this on (2.66 version, 2 machines with 1Gb RAM, 1 machine with 3Gb RAM), latest OS 10.4.7
Starting in safe mode makes no difference on either Mac Pro

I am running two 7300 GTs in my 2.66 GHz Mac Pro driving (2) 20" + (1) 30" Cinema Display. I am not seeing the issue you mention in iMovie. Quicktime flickers every once in a while when playing iTunes video content, but that started with the iTunes / Quicktime upgrade, not when I added the extra card.
I have my nVidia 7300 cards in slots 1 &2 each running 8 lanes. Might be worth a try. The 7300 is not that "high performance" that running in 8 lanes is going to make a huge difference in speed. What it will do for you is get the cards on an equal footing.

NVIDIA 7300 vs ATI HD 2600 (on iMac)

Trying to compare the current top-end iMac to the current bottom-end Mac Pro. It's quite tricky! My particular area of interest is editing High Def videos in FCE. Also running Parallels with Windows XP.
I'm curious to know how the iMac's ATI Radeon HD 2600 compares to the NVIDIA 7300 GT. I know that the ATI 1900 is supposed to run rings around the NVIDIA, but what about the HD 2600?
Also, how can one compare the 2.8GHz Core2 extreme to a pair of 2.66 "Woodcrests"?
I really like the expandability of the Mac Pro (the first thing I'd do is sling a couple of 1TB disks in).
Of course I'm also watching what upgrades come out this quarter, but money IS an issue, and I'm hoping that we'll see a lot of cheap current generation Mac Pro's around that I could buy with 24" screen for a similar amount of money as a comparable iMac.

The 8800GT is known to be a killer performer, only being around 10% slower than their fastest card, the 8800 Ultra.
It is also, roughly, 2X faster than the X1900 XT. I can;t wait for Apple to sell the upgrade.
The rest of the Mac Pro's - comparing the 3.0 GHz Harpertown vs my current 3.0 Clovertown shows almost no difference - 10% or so. I am surprised with all the extra memory bandwidth and the greater cache and the faster dividers and all that the speed difference is so low.
The 2.8 Harpertowns are essentially as fast as the 3.0 Clovertown's, perhaps even faster. Faster still with the 8800GT card, yet almost $1,000 cheaper than the 3.0 system was yesterday - and with BT and an extra GB of RAM to boot.
I'd say that's a great move by Apple.

Leopard/nVidia 7300 issue on my mac pro?

My Mac Pro running Leopard and a Nvidia 7300 refuses to run pixel & vertex shaders in Halo. I'm not sure why... it just quits if you try to run it with those settings.

I'm having the same issues on a MacBook Air (2013), running Mac OSX 10.8.5, so it's not just a MacBook Pro issue. I went to the Apple store Genius Bar today, as I had tried everything I knew how to do with restarts,
PRAM reset, etc..and they're ordering a new logic board (I'm luckily still under AppleCare warranty)..
But this problem has surfaced on a number of Apple community and other Mac support forums..
You may need to take it in and see if it's your hardware :-(

Video support on a live CD

Most live CDs don't have proprietary drivers installed to work on as many machines as possible.
Normally for Arch you install
in the following order:pacman -S libgl (you don't need it if you have a nvidia card) > pacman -S xorg > pacman -S mesa > pacman -S your_video_card
so my question is by simply skipping the last step,
will you be able to get video support working everywhere?
(I haven't tried to not do that last step yet to
see if it'll work but just want to be sure)

Nvidia 8800GT video card in the First Generation Mac Pro

This message is a bit of advice if you install the new Nvidia 8800GT video card in the first generation Mac Pro. The advice is keep your old video card. The old video card will be needed if you ever need to reinstall the OS X operating system. This new card needs the video drivers (kernel extensions) that are in OS X leopard 10.5.2 or later. With this video card installed, both the OS X original installation disk that came with this computer and the OS X leopard upgrade disks will cause a kernel panic when booted up. This is because they do not contain the kernel extensions needed for this video card. There is a question. Does anyone know how to create and burn a reinstallation DVD with OS X leopard version 10.5.2 on it? This would help solve this reinstallation problem

this is a advisory to whom it may concern
here my latest reply from a apple product specialist how was very good and helpful but only
give me this to my upgrade answer !
i want to upgrade my graphic card to 8800 and run tiger on my 1st gen macpro
here it goes:
"This article indicates what cards are supported in what machines: http://docs.info.apple.com/article.html?artnum=305346
Your Mac Pro is the first generation, and did not have PCI-Express 2.0 slot like the current generation does have.
Unfortunately, we don't foresee the release of any drivers for the 10.4 OS on this machine.
In regards to the second issue, we also don't support two video cards in two slots, using a different one for eash OS, there is no supported way to do this."
"Unfortunately, the latest version of the Mac Pro will not run Tiger, as it was manufactured after the release of Leopard, therefore the drivers for the machines hardware will not be available on Tiger."
hope thats cleared some ones Q.
kindly

No video support with iPad lightning-VGA adapter (iOS 8.3)

Just subscribed to HBO NOW and bought a lightning-to-VGA adapter ($55!) to watch HBO on my computer monitor (no HDMI, only VGA) from my iPad mini. Worked fine on iOS 8.2, but then when upgraded to 8.3 I could no longer get video support. Still have iOS 8.2 on my iPod Touch, and when that device is connected to my computer monitor, I can watch HBO (and Netflix). So obviously 8.3 no longer supports video with a lightning-to-VGA adapter. Is Apple aware of this? Will there be a fix soon?

I had the same problem with an iPad Air 1 once I upgraded to ios 8.3. Following several suggestions online, I did the following:
1. Via iTunes Store app, I logged out.
2. Settings, General, Reset (all the way at the bottom), Reset all Settings (this doesn't remove any data/apps/etc, it just resets all the iPad settings.
3. Did a Hard Reboot (hold down power and main button until iPad shuts off).
Once I turned it back on, now I could use the iPad via lightning adapter to watch video on a TV.
