Is it possible to replace the graphics card into a better one?
Hi, thank you for your great work.
I would like to know if it is possible to change the graphics card of my iMac, so that, for example, I can use the OpenCL technology in Mac OS X 10.6. I know from MacTracker that the graphics card connector is MXM.
If it is possible, how? Thank you.
I ordered the card from weloveMacs.com. I had the nvidia 7300 with only 128MB memory. I ordered & installed the NVIDIA GeForce 7600 GT VRAM 256MB Video card for $299. It was about $338. Withbexpedited shipping. I did take some pictures that I could send you with comments if you like. I had replaced the HD on this machine before. That was fairly easy. Everything I read about this video card swap made it sound particularly hard and daunting. It really was not.
Yes, the profiler recognized it immediately. My screen is brighter and my games are much faster too. The whole machine seems faster.
it might be physically possible, but I've not heard of any great selection of cards that would fit this model, although I've seen at least one place advertising iMac graphics cards (but expensive!!) Not 100% sure cards other than the standard 7300GT and 7600GT would work with this model iMac, I think you may have to also worry about drivers?
I too just replaced a failing 7300GT 128MB with a 7600GT 256MB card. I found upon disassembling the iMac that the heatsink mounting screws had come loose, causing the card to overheat and fail.
An interesting side note is that the iMac used to have a faint screen burn-in covering the lower half of the display. After replacing the graphics card, the burn-in is gone! :)
