can someone help me with my mining setup?
i recently switched from an nvidia card to an amd card. deinstalled all the graphics drivers (through device manager in win8), then installed the amd catalyst driver.
now when i run cgminer, i get a hash rate of like 5kh/s with my r9 270x and it doesnt even seem to be doing sth at all...
here is a screenshot:
im running the standard config: ultracoinminer -o stratum+tcp://utc.greekpool.eu:3337 -u user -p password --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600
changing thread concurrency and other stuff either results in hashrate = 0 or in an error (the 270x config in this thread gives me an error).
whats up with that. is it possible that this happens because i switched graphics drivers? if so, how do i get this fixed?
You also need the AMD APP SDK
http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/#onehere
and make sure you delete any .bin files in the miner folder before you start
We have the same card. Try this
ultracoinminer -o pooladdress -u username -p password --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 --thread-concurrency 15508 --lookup-gap 2 -w 256 -I 19 --no-submit-stale -g 1 --expiry 1 --queue 0
I get 350-355khs with that setting on my cards
Edit: oops didnt read it thoroughly
Did you totally remove all the nvidia drivers? maybe theres still something left that stops the amd card
try google ther's a lot of instruction to complete remove it
