Still no miner for older AMD GPU cards?
I have successfully built
https://github.com/tpruvot/sgminer for AMD R9, works with my 280X and 290X, but the hashrate is very poor, 2 to 3MH/s by card. They actually are not used at their full power as --odgc and --odgt shows, even with an intensity of 23 (crashes at 25). Any advice welcome...
Yes, please if you can.
Well I already can tel you how to build it, tell me if you also have poor performances:
This is for Debian, which I use. I will assume you already have the AMD SDK installed in /opt
$ apt-get install libcurl4-openssl-dev pkg-config libtool libncurses5-dev
$ git clone https://github.com/signatumd/gpuminer-source.git
$ git submodule init
$ git submodule update
$ cd submodules
$ git clone https://github.com/akheron/jansson.git
$ find . -name ".deps" -delete
$ cd ..
$ autoreconf -i
$ CFLAGS="-Os -Wall -march=native -I/opt/AMDAPPSDK-2.9-1/include" LDFLAGS="-L/opt/AMDAPPSDK-2.9-1/lib/x86_64" ./configure --disable-adl --disable-git-version
$ make clean
$ make
$ make install
At this point you'll have sgminer installed in /usr/local/bin and you can start it with:
/usr/local/bin/sgminer -k skunkhash -o stratum+tcp://sigt.pool.mn:8732 -u foo.bar -p baz -I 20,20,20
Of course you'll have to modify the values to match your worker and pool.
Please tell me what hashrate you get!
