1 Graphics Card Not Detected
hello all,i have a 2011 27 emc 2429 imac,the last month the gpu showed some problem like flashing screen,reverted images, and things like that,so i decided to replace the gpu an amd 6970 1gb with a new one amd 6970 2gb.
When i starts the mac the screen remains black and after few seconds fan runs at high speed,so i checked the led on the logic board and i saw that only the led 1 and 2 lights up ,while led 3 and 4 are always off also after the imac starts .
The problems seems that the gpu isn't detected ,anyone know wich component could be broken ?
(the gpu works on a pc and is correctly detected )
Update (05/10/2016)
ok,thanks,i think that i will sell the gpu and then i will buy a new one for mac,because i had also checked online but seems there isn't a guide or other for flash the card or bios
in the meantime i can in someway use my imac, i mean with the intel integrated graphics?
because at the moment with or without graphic card the lcd remains black and i'm a little worried that there is another problem
Questa è una buona domanda?

Check the GPU is compatible with macs, most hardware is not...

Is this a replacement GPU MXM II board? Apple uses its own firmware on them and only the boards Apple used for that given model can be used.
