iMac 24" A1225 Graphics Card Change
Hello there,
Is it possible to change the graphics card in my 24" iMac A1225 (NVIDIA GT130 512MB) to an "normal" NVIDIA GT130M Card?
Kind Regards,
Chris
Is this a good question?

Doing a hot air workstation reflow of the GPU on this model has been about 75%
successful for me.
UPDATE
Here's a video on doing it:

If you mean a desktop PCI card that fits into one of the 4 to 6 slots it has - No.
The card Apple uses is called a Mobile PCI Express Module (MXM)
You will need a GPU card that was designed for your system. In addition it also needs the custom Apple firmware. So your choices are a bit limited.
Can you give us a bit more here on why you want to change out the GPU.
For reference here is a listing of possible GPU's your system can support:
- ATI 4850 Graphics Card w/512MB- Apple P/N 661-5135
- NVIDIA GeForce GT120 w/256MB- Apple P/N 661-4991
- NVIDIA GeForce GT130 w/512MB - Apple P/N 661-4990

Your systems specs: iMac 24" 3.06 GHz Core 2 Duo (Early 2009)

Has your current card failed?

Yes this is the right model!
Yes, the other Card is a MXM Card, but with 1GB RAM.
Same connectors but a little bit smaller dimensions.

In this moment my card shut´s down the imac on different times.
Sometimes the Mac runs hours without any problem, and at other times
it shut´s down after logging in.
I tried the same card from a friend (same specs), this card run´s without problems.
So I thinking, the problem is the graphics card.
A new card is (for this old IMac) to expensive, so my (noob) thought was to replace the card with a "similar"
MXM Nvidia GT130 card.
I read times before, someone tried it, but there was a black screen while booting and at the desktop it runs.
But is it real? I´m not sure...
Thanks in advance,
Chris

Isn’t there a guide that can show us how to do this? I’m not sure where is the video card even is. I ordered a replacement, pretty sure I got one that was made for the A1225
