Title: Xubuntu 12.10 mining rig with 2x7950 low hashrate Post by: tonightwefeast on April 28, 2013, 02:28:58 PM Hello there,
I wondered if anyone else had the same problem as me and if so how they went about fixing it. Basically when mining using 2x Sapphire 7950s on Xubuntu with CGminer I only get about 500 kh/s (LTC mining) between the two GPUs, if I disable one of them I still get 500 kh/s. The problem has been solved here : Code: https://bitcointalk.org/index.php?topic=178963.0 I'm unsure however about how to go install catalyst 12.8 as I just follow the guide on: Code: http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-linux Code: sudo apt-get install fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev And there is no mention of installing a specific catalyst let alone how to go about installing a different one. If anyone has any advice to offer that would be excellent, TWF Title: Re: Xubuntu 12.10 mining rig with 2x7950 low hashrate Post by: frozen on April 30, 2013, 02:20:13 PM The thread you linked where this problem was solved also provides a link to catalyst 12.8:
