I’m happy to report that all is well again and I’m back to doing what I’m good at, which is editing and not having to deal with technical problems. My iMac was apparently defective because after exchanging it with a new one with the same exact specs, everything is working as it should be. A few things to note: I haven’t put in any third party memory, just using the stock 8gb for now. I also didn’t connect the ONE, just using the onboard audio. Furthermore, I installed the latest CUDA drivers and used that instead of OpenCL. The WD dual Thunderbolt drive is working like a dream with RAID 0 and I haven’t had a single problem since I started editing a few hours ago. Going to send back the Kingston RAM and pick up the OWC ones. Anyway, I’m surprised it was the computer itself that was defective but I suppose it happens. I wonder what exactly was wrong with it that caused so many problems. Thanks to everyone for taking time to answer some questions. Cheers!
