I wanted to give some feedback, after a lot of research and feedback from Fullzero I would recommend to anyone that it issuing a 4-6 GPU system to use 8GB of RAM minimum instead of 4GB. I have been running my system now for 5 days and have not had any "random freezes/crashes" even with pushing some OCs in testing the new ver 0017. I think this is something we overlook.
What makes you think that there's a need for additional RAM? Top is showing that I'm not using more than about 1.2GB with four cards. I'll test this weekend on my 6 GPU system, but doubt it would use more than 2GB
I thought the same thing until I really looked into it fullzero had suggested it had to do with the possibility with the DAG and virtual memory for Linux and or Windows. Before I had random freezes, kept the same settings, added the RAM and no more issues.
