Is it possible to upgrade graphics card on imac

I just upgraded my I have this same issue. Same model and took out the and replaced with Turn it on and makes the chime but screen is black. Double checked and the lcd screen is defiantly plugged in correctly. Have you had any luck?? I havent upgraded mine yet. However, from the videos Ive watched and my research, it seems that when you upgrade the gpu you will no longer have a boot screen, meaning the apple logo and loading bar will not show while the system is starting up anymore.

I would try turning it on and giving it a few mins and the desktop should pop up after the system gets fully booted up. Also some people say that it may take a little longer to boot up with an upgraded graphics card, I believe. The only way you will still have a boot screen is if you take a gpu out of a newer mac and place it in a older one. Otherwise, any aftermarket ones will not show the boot process.

Thomas Meijer thomasmeijer I'm curious about this to, since the GPU is a swappable card it should theoretically work, getting a will be the only problem or iFixit will make it possible ; Love to see someone trying this!

For the CPU upgrade, see this thread , here we talk about upgrading from a dual-core to a quad-core. Dave Nielsen. Thomas Meijer or Dave Wu, did either of you have luck with this? I'd love to put in a Radeon or even better go straight to the It'd save my life :. Dave Wu. I bought my on Gainsaver and it did not work for me at all. I can't verify whether it was a faulty GPU or that it just wasn't compatible.

There was no boot chime or anything, I even tried a new power supply. I ended up ordering another Radeon and it ended up working fine for a few days, then it kind of crapped out on me. I can still boot and I think it actually loads up fine, because when I hit the volume, I could hear the clicks! Since apps default to the GPU associated with the primary display, this option works with a variety of apps: Quit any open apps that you want the eGPU to accelerate on the primary display.

Select Displays, then select the Arrangement tab. Drag the white menu bar to the box that represents the display that's attached to the eGPU. Open the apps that you want to use with the eGPU. Also make sure that the cable is connected directly to a Thunderbolt 3 port on your Mac, not daisy-chained through another Thunderbolt device or hub.

If you have questions about Thunderbolt 3 chassis or graphics cards, or about third-party app support and compatibility, contact the hardware or software provider. Software developers can learn more about programming their apps to take advantage of macOS eGPU support.

Apple added support for eGPUs a few years ago, made possible by the addition of Thunderbolt 3 ports on Macs.

These have very high throughput, making it possible for a GPU in an internal enclosure to offer almost as much graphics processing capability as one connected internally. But for anybody looking to extend the life of their existing Mac for a few more years to wait and see how the Apple Silicon transition shakes out, updates from Apple and key software partners make an eGPU a great choice.

Here are a couple of Thunderbolt 3 eGPU enclosure options out there for those considering this upgrade path, and the relative merits of each. But the good news is that you can continually upgrade and replace these graphics cards to give your Mac even more of a boost as graphics tech improves. Active 3 years, 3 months ago. Viewed 35k times.
