How to "enable" the discrete AMD GPU on a Late 2011 15" MacBook Pro

Hello,

Okay, so I just bought a Late 2011 15" MacBook Pro (8.2) for really cheap and everything works fine. It as a 2.20 Ghz Intel Core i7 CPU and a Intel 3000 series integrated GPU. Except, I heard it also has an AMD discrete GPU according to specs sheet. Upon looking on the internet, this model year was especially known for problems with the discrete GPU. I reinstall the OS, but notting. I wanna how to enable it in any possible ways. Maybe some of you guys can help me. Thanks!

Thanks for your help, but I tried this with no avail. There’s notting and when I go to System Repport, theres only the Intel intagrated GPU. It’s like this OS can’t see it. I know I have one discrete GPU because i’ve thorne the computer apart and I saw the AMD chip. I think the previous owner disable it but I’m not sure.

Are you sure? Run a graphics intensive sw such as Unigine's Heaven or Valley in window mode and check if the AMD is really out. If yes it may be the the discrete card, although not simple to do, could have been disabled because defective.

Okay,

So the previous owner told me that he, indeed, deactivated the discrete GPU for issues he experienced in the past. Those issues are really common for the 2011 MacBook Pro’s. Thanks for everyone for helping me! 😊

See if NVRAM/PRAM reset helps.

Please check your Mac's EFI Boot ROM and SMC firmware versions and update/restore accordingly.

The discrete GPU will only turn on if it is needed. The easiest way to trigger that is to plug in an external display.
