1  Alternate cryptocurrencies / Altcoin Discussion / Two 6950 getting very low hashrates in Ubuntu 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?

try it with the flag -n

Like this?

cgminer -o 54.225.76.105:6327 -u 8bJvPBpSBvY6r9UzKVUzokUkJ2rRMpgL1F -p 8 -n

Crashes too...

Hi,

A friend of mine who was mining bitcoins 2 years ago has convinced me to start mining Bytecoins.
I want to mine for this pool, but nothing seems to work.

I first tried GUIminer, which I set up like this: https://i.imgur.com/58BUEo7.png
But I kept getting these errors:

Quote
2013-04-11 18:20:04: Listener for "Default": 54.225.76.105:6327 11/04/2013 18:20:04, Verification failed, check hardware! (0:0:Barts, e66901a7)

I got these errors with multiple pools.
Then updated my driver, but now GUIminer won't start up at all.

Okay then I thought, maybe try CGminer. This is what my StartMiner.bat looks like:

Quote
cgminer -o 54.225.76.105:6327 -u 8bJvPBpSBvY6r9UzKVUzokUkJ2rRMpgL1F -p 8

but when I run it (click on StartMiner.bat) it just crashes: CGminer has stopped working

So am I doing something very wrong or does every piece of software just hate me?
