I suggest mining Ethereum with the two 3GB cards. What you heard is mostly correct. The current DAG size is a little over 2GB. Not all VRAM is usable for a DAG, so as the DAG size grows at some point in the relatively near future a 3GB card will not be able to mine Ethereum. That's still several months
This is one of the essential differences between Bitcoin mining and Ethereum mining, in that Ethereum mining was designed to be memory-intensive, so as to prevent usage of ASICs and other Based on current estimates for DAG size and memory requirements, mining with an RX 470 4 GB should yield:.
28 Sep 2017 ethOS is a 64-bit linux distro that mines Ethereum out-of-the-box, allowing you to control all your rigs from a single location, and drill down to specific GPUs --cl-global-work n - the OpenCL global work size Before trying to overclock our GPUs, we must first determine the current frequencies of our cards.
