Overclocking AMD 7950s in Ubuntu, only 1 appears affected

[ayoungtech]

Good morning everyone. Sorry if this is in the wrong section.

I'm currently mining Zcash using 3 7950s running 14.04.2 Ubuntu, with Claymore's v11.1 miner. The mining is working well. All three cards are recognized. Without overclocking, I get roughly 215H/s from each card.   After overclocking using aticonfig commands, GPU 0 will go up to 240H/s, but the other two will stay around 215H/s.   When I type "aticonfig --list-adapters", all three cards are listed.    Am I missing something? It doesn't seem like the other two cards are being overclocked.

Thanks!
