Hmm, glad that it worked for you guys. I tried that both with lasys and the "14.6fixed" miners, didn't see an increase on my 7950s though.
I think that it might be a problem with win8.1 and the 14.4 drivers because I noticed that I actually lost about . 1Mh per card after "upgrading" from win8 to 8.1 and running 14.4 modded driver (I have six cards) and lazys miner like I had been.
I'm running Windows 7 with the 14.4 v3 mod drivers, lasybear's miner (sgminer_x11x13mod_03_06_2014.zip), and Pencha's BIN file.
I have 6 GPUs per machine and get 3.7 m/hash per card @ 1080/1500.
How much are you getting currently?
