ETH DAG was moved from HDD to VRAMs
v4.0:
- no DAG files anymore.
- removed "-dir" option.
- Bug fixes.
you all might wanna try old claymore ETH miner below version 4.0
take a look...might work or might not.
Interesting, that Dag creation for 4gb cards gives a pain, well if it is working it will gives a constant relief to us and to all rx 570 4gb user, by the way since this is an old version of claymore, do you think that the old amd driver will work for it? How about blockchain driver?
i don't know...only experimentation will solve this question.
looked at the readme.txt
This miner is free-to-use, however, current developer fee is 2.5%, every hour the miner mines for 90 seconds for developer.
If you don't agree with the dev fee - don't use this miner.
This version is for recent AMD videocards only: 7xxx, 2xx, 3xx and 4xx, 2GB or more.
There are builds for Windows x64 and for Linux x64 (tested on Ubuntu 12.04). No 32-bit support. No NVidia support.
LOL at 2.5 dev fee,
file name is "Claymore's ZCash AMD GPU Miner v3.1 Beta - Catalyst 15.12.zip" ...that's the driver most of the time it works with later driver versions up before "crimson drivers"
rx 570 is just a refresh of rx 470, so it might work.
