Display cable different between 1.6 and 2.8GHz logic boards?
I have a couple of late 2015 iMacs with the 1.6GHz i5. After looking at the insides and photos on eBay of 2.8GHz logic boards, I decided to take a chance and buy one.
Replacement went smooth thanks to ifixit’s guides, but when I got to the display data connector, the connector on the 2.8GHz board is approximately 3mm wider than the one on the 1.6GHz board, and my display data cable does not fit. I can boot the machine on an external monitor to confirm it is a 2.8GHz board, non-4K, but of course it’s throttled heavily due to the temperature sensor being disconnected.
EveryMac claims that there’s no difference in the displays between the 1.6 and 2.8GHz 21.5” late 2015 iMacs. They also say the “Retina” machine in this line is the 4K 21.5” imac. I can’t find anywhere else that says the 2.8GHz logic board uses a different display. I was kind of hoping to get another year or two out of these machines and now I can’t bring myself to put a sub-2GHz CPU back in it.
What did I do wrong? Why are the connectors different sizes? Is there some sort of adapter to connect my smaller data cable to the larger connector? Why is the connector larger if it uses the same panel? Buyer pays return shipping! I need your help. Thanks.
