This could lead to slower speeds later on and shorter lifespan for the SSD. The biggest downside of using USB versus internal SATA besides the slightly lower speed is that there is no TRIM support for USB drives on MacOS. Overpriced when you can get a SATA SSD and enclosure for much cheaper, and have the flexibility to use that SATA SSD internally if you wanted. I wouldn't do something like the T5 unless you already had one sitting around. It is cheap, faster than your HDD, and gives you the option to one day swap it with the HDD.

Modify it (underclock) using AMD Application.Ĭheck for guidance and necessary software/applications. Copy the vBIOS of the GPU to PC (need Windows OS, GPU-Z application) After successfully rebaking the GPU, your iMac will work, but to keep it last longer, you can under-clock the GPU. Big repair shop may have the GPU reballing/reheating machine to apply heat on both sides of the GPU chip, but they will charge higher.Ĥ. At home, DIYer use the oven (200 degree Celcius for 8 min), but a repair shop just need a hot air station and some patience to apply hot air only to the GPU main chip. Replace the old HDD with new SSD and install/move your data over to the SSD.ģ. You can ask the local shop to make a quotation for the following servces:Ģ.

You already got the white screen at power-up, then backlight board and the whole LCD panel is working fine. Your description is clearly a GPU failure signature, which is very common with iMac 2011 and 10 years of use. To get the iMac work as the screen (Target Display Mode), you need to get to the log-in screen first, which doesn't work in your case.
