Title: Two 6950 getting very low hashrates in Ubuntu Post by: Jasp3r on December 17, 2013, 01:46:36 AM Hey guys,
My Windows 7 crashed as I think something on the harddrive became corrupted, I got around 840kH/s there. After the crash I installed Windows 8.1 but the AMD drivers suck so hard that I cannot get the mining to work so I tried dual booting Xubuntu. I followed this guide: http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-linux/ And this is what my mine_litecoins.sh looks like. #!/bin/sh export DISPLAY=:0 export GPU_MAX_ALLOC_PERCENT=100 export GPU_USE_SYNC_OBJECTS=1 cd /home/jasper/cgminer-2.11.4-x86_64-built ./cgminer --scrypt -u *not gonna tell you this* -p *not gonna tell you this either* -o stratum+tcp://doge.cryptopool.it:3322 -w 256 -I 18 -g 1 --thread-concurrency 8000 And for some reason I only get 300kH/s COMBINED. When I start it up for a split second it tells like 550kH/s per card which is impossible and then it goes back to ~150kH/s each. Anyone know what is wrong? |
