Hi, Neotil:
You said you started this thread to help users with this motherboard, and I hope you can help me. I installed Yosemite without much fuss on a new 4TB drive, keeping my existing Mountain Lion drive as a backup. ML worked flawlessly, BTW. Everything seems to have installed perfectly and most of the time my hack works very well, but every once in a while, as in days of up time without incident, the whole system just freezes. No SBBOD, no kernel panic messages, no black screen - just frozen video and no activity on the HDD, unresponsive to everything and I have to push the reset button. I have no idea how to diagnose this issue and the Internet is being less than helpful.
I use my hack mostly for Final Cut, PhotoShop, and as a Plex server. Most of the freezes have happened when the system was only transcoding for Plex. Twice it's frozen while I'm working on it, once in FCX, and once while running Yate to reorganize my music library. All three programs are kind of intense on CPU and memory, but not /that/ hard.
Any ideas?
