Hello,
I know this is a long shot since the 7740 is „ancient“ at this point. I had/have the Quadro RTX 3000 installed and wanted to upgrade to the 5000. So I researched the parts number and found out that I also need the 40 Pin display cable. So I bought both and was happy to upgrade, only to finde out once I got to the back of the panel, that the port on the panel isn’t the right one for the 40 Pin connector… kinda obvious in hindsight but I feel pretty stupid rn, with the disassembled Laptop in front of me after the point of no return…
me question now is: do I need ANYTHING else for the upgrade like a bigger heatsink? And a different power cable? I even asked the seller of the gpu if I needed anything else besides the display cable and he just said no… please help me🥲
