Hi guys, I hope you can help me out here,
I posted here earlier already but I get this error:
error -4 enqueueing kernel onto command
i have 4 R9 280x and 4gb is that the problem?
in short i believe yes for more than 2 cards mining u need 8 gb ram minimum
I find that a good rule of thumb is 4gb per card, I have rigs with 4 x 290 and they were fail at 8gb so I installed 16 gb and it worked just fine. If I were to make a guess I would imagine you need to match your combined GPU memory in available system memory.
More system ram does nothing for mining. I've seen 6gpu rigs running 2GB (linux). 4GB is all you need for Win.
