sure there is a difference, roughly 30% increase in hashrate. you have to update your drivers to 14.6 or ask someone to provide you with the kernel bin files compiled by sgminer on machine running 14.6 drivers. then you can use these kernel bins on mining rig with 13.12 drivers and get almost the same hashrate as with 14.6 drivers

I just did a fresh install with the 14.6 drivers and am still getting the same rates as before, even with a direct c&p your config.
I originally tried to just update but ran into problems hence the fresh install.

I even checked with
dmesg | grep fglrx | grep module
and it verified that I had fglrx 14.20.7 installed. (downloaded the 14.6beta driver right off of AMD's website)

Any ideas?

Edit: Additional details about my set up:
2 Sapphire 270x
Ubuntu 14.04 fresh install using unity desktop.
I'm focusing on x11 and x13 right now. x15 causes crashes no matter what I do. If this is all I can get nbd.

Delete your old .bin and restart.
My conf for a 270 with 14.6rc2 driver
2.6Mh on x11
2.0Mh on x13
1.6Mh on x15
8.2Mh on nist5
