That is GPU 0 that is showing 0.00 hash.
Probably need to watch miner output when it starts to see error message why its not hashing.
Is gpu0 a 4gb rx580? Also is your driver anywhere near current?
Windows uses some of the memory of the first video card for some reason (linux does not suffer this).
Post up what the miner is showing when spinning up and any error message it is showing about gpu0.
Also your command line.
1) no its 8gb
2) driver is crimson beta old version (but it worked 1 week ago with no problems)
3) miner stil works with no error message
4) command line? can you explain what this means and how to post it
p.s i have updated to new driver but still the same.. and then downgraded again
thanks for your reply
Did you try and Linux OS, like MMPOS or HiveOS?
