In this video, we replace the faulty GPU with a much more reliable one, to keep this iMac running well for years to come!

What this that you spraying ?? I having problem with my Imac 2013 model my display wont turn on but I hear the charm but no logo apple thanks and also replaced mother 3 times and still no picture on the screen and also change the bios battery and DDR 3 ram and changed the thermal on the cpu thanks please help
i did all this a year ago and it lasted maybe 14 days
I think I have this problem. Can I send the computer or do I need to bring it to you? I'm in London.
That's expensive for a cheap second hand replacement card, €100 materials and two hours work max. I hope you flashed it to mac since if not there's significant shortcomings. No startup screen so no system picker, no second screen possible and no brightness control. Your information about baking the cards is also erroneous. I was sceptical but I've now done three by simply baking the card whole in a domestic oven at 300ºC for eight minutes. One didn't work at all (it's symptoms were different as the mac wouldn't even start until I took it out) but the other two are still going strong over two years later and one of them works 10 hour days, six days a week in a busy architects office!
They're replacing it with a lower model amd chip. They aren't upgrading it. For the price charged I would have expected a newer gpu that would be much less prone to failure
Annoying music and no further explanation, that´s how I like it. What did You do to the heatsink and how? What did You do to make the card work without problems? Reportedly non Apple Gpu´s need to be flashed or a patcher must be used. Only with a flashed Gpu we get bootscreen.
So: this sucks.
400 degrees for 9 minutes
